Connect your AI agent and just say what you want. It runs cold emailing, email warmup, LinkedIn, WhatsApp and Instagram outreach, multichannel sequences, and email verification for you — over a 200M+ B2B lead database, from one workspace. Plans start at $14.99/month with a 7-day free trial. WarmySender is built for SDRs, founders, recruiters, lead generation agencies and growth teams who want outbound to run itself without putting a single account at risk. HOW IT WORKS 1. Connect your AI agent. Point Claude Desktop, Claude Code, ChatGPT, Grok Bot, OpenClaw, Cursor, Windsurf or Zed at warmysender.com/mcp with a key from Settings — each ships with a one-paste install snippet. Any other MCP client that speaks Streamable HTTP (Continue, Cline, Goose, custom agents) works too. Then plug in your mailboxes, LinkedIn, WhatsApp and Instagram accounts in the app — done in minutes. 2. Tell it what you want, in plain English. "Launch a cold email campaign to these leads, follow up on LinkedIn, and DM the ones who open." Your agent builds the sequences, verifies addresses, and enrolls prospects across every channel. 3. We keep every send safe. Peer-to-peer warmup builds your sending reputation with real threaded conversations, and pulls warmup mail back to the inbox automatically if it lands in spam. The scheduler paces every email, LinkedIn touch, WhatsApp message and Instagram DM inside safe daily limits and your ramp — no matter who's driving. The agent never sends a message, DM or invite itself, and no agent and no setting can raise a limit. Connecting and disconnecting accounts always stays in the app. 4. Watch the replies roll in. Every reply lands in one unified inbox across all channels. Ask your agent to pause cold prospects, follow up with warm ones, and route hot leads wherever you work. EVERY CHANNEL IN ONE PLATFORM Cold email — multi-step campaigns built, launched and paced for you, with merge fields, spintax, A-Z testing across 26 variants and mailbox rotation. Email warmup — A.H.D.E. (Authentic Human Deep Engagement): peer-to-peer threaded conversations up to 5 replies deep, always on, and unlimited on every plan. LinkedIn — connection requests, messages, InMails and post engagement, plus post publishing and scheduling, saved audiences, multi-account rotation and per-account proxy routing, all inside per-account caps and a gradual ramp. WhatsApp — message from your own number, on a gradual ramp up to 60 messages a day per number. Instagram — auto-follow, like, comment and personalized DMs across rotating accounts, capped daily and hourly. Multichannel sequences — a visual drag-and-drop builder with 8 conditional branch types, mixing email, LinkedIn, WhatsApp and Instagram steps in a single campaign. Email verification — Bounce Shield checks every address the moment you upload it, with honest flags for catch-all domains like Outlook and Yahoo, so you know what's deliverable before you send. 200M+ B2B lead database — search, filter and enroll prospects without leaving the workspace. Plus AI-powered subject lines, a real-time mailbox health view that flags problems before they cost you replies, analytics across email, LinkedIn and warmup, and multi-workspace and admin controls for agencies running outreach for many clients at once. Your outreach, on autopilot. ## WarmySender Reviews ### 1. WarmySender puts A lot of useful tools in one place **Rating:** 5.0/5.0 stars **Reviewed by:** Daron S. | Marketing Strategist , Marketing and Advertising, Small-Business (50 or fewer emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through a business email account **Source: Organic:** Organic review. This review was written entirely without invitation or incentive from G2, a seller, or an affiliate. **Reviewed Date:** September 25, 2026 **What do you like best about WarmySender?** What I like best is that WarmySender brings the pieces I need for outreach into one place: finding leads, verifying email addresses, warming up mailboxes, running campaigns, and managing replies. I’m still getting my campaigns set up, but it’s clear there’s a lot I can do with it. I also appreciate how the team communicates. Their emails are useful, they provide plenty of instructions, and the founder seems personally involved. That gives me confidence that they care about helping customers actually use the product. **What do you dislike about WarmySender?** I’m still getting my first campaigns set up, so I haven’t run into a major problem yet. My main challenge is the learning curve. WarmySender does a lot, and it can take time to understand how the sending limits, warmup, verification credits, and campaign settings fit together. The instructions are helpful, but a guided checklist showing what’s ready, what still needs attention, and what each limit means for a new campaign would make it easier to get started with confidence. **What problems is WarmySender solving and how is that benefiting you?** Before WarmySender, putting together a prospecting campaign meant piecing together separate tools for leads, email verification, warmup, sending, and follow-up. WarmySender gives me one place to manage that process, which makes it easier to build targeted campaigns and keep track of replies. I’m still setting up my first campaigns, so I don’t have honest numbers for time saved or new business yet. The immediate benefit is having a clearer process and the tools to check a list and prepare a sending mailbox before outreach begins. I’ll be able to judge the business results once the campaigns are running. ### 2. Real deliverability gains with smart auto-throttling **Rating:** 4.0/5.0 stars **Reviewed by:** Cyriac Z. | Founder, Small-Business (50 or fewer emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** This review contains authentic analysis and has been reviewed by our team **Source: Organic:** Organic review. This review was written entirely without invitation or incentive from G2, a seller, or an affiliate. **Reviewed Date:** September 18, 2026 **What do you like best about WarmySender?** The warmup engine actually works and reports real numbers, not vanity metrics. Across 6 mailboxes on 3 domains we're seeing over 97% inbox placement and a 0.2% bounce rate. What stood out most is the automatic throttling: when one mailbox's warmup mail started landing in spam, WarmySender cut its volume on its own to let reputation recover, instead of letting me find out the hard way through a real campaign. That's the kind of protection that's easy to undervalue until you've been burned by a domain going dark. The lifetime deal pricing also makes it a strong value for building real sending infrastructure rather than a one-off tool. **What do you dislike about WarmySender?** The lead database has a real gap between browsing and saving results: searching is free, but saving a lead consumes a reveal credit, and that distinction isn't obvious the first time you use it. Mailbox connection also assumes you're comfortable with your provider's 2FA and app-password flow, which added real time to onboarding, though that's more the email provider's process than WarmySender's own UI. **What problems is WarmySender solving and how is that benefiting you?** We needed to stand up cold-email infrastructure across multiple domains without burning our primary business domain's reputation. Before this, sending any real volume from a new domain was a guessing game with no visibility into placement. Now WarmySender's warmup lets us build sender history on fresh domains safely before pointing any real outreach at them, and the automatic reputation protection means we're not manually monitoring six mailboxes for spam drift every day. We went from one mailbox we were afraid to push volume on, to six mailboxes with measured, defensible deliverability data. ### 3. Effortless Email Warmup with Cost Savings **Rating:** 4.5/5.0 stars **Reviewed by:** Matias C. | CEO, Small-Business (50 or fewer emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through a business email account added to their profile **Source: Organic:** Organic review. This review was written entirely without invitation or incentive from G2, a seller, or an affiliate. **Reviewed Date:** September 06, 2026 **What do you like best about WarmySender?** I like how WarmySender solves the warm-up of emails really well and acts as a cheaper alternative to other services. I appreciate the good pricing, which makes it accessible. Additionally, I enjoy how the UX and overall experience within the app is designed. The specific features I value the most include the warm-up tool, email sending, and the email verifier. The initial setup was also really easy because I didn't have any other tools to connect it to. **What do you dislike about WarmySender?** I find that the deliverability of emails and the tracking of deliverability with WarmySender isn't always as accurate as expected. It's challenging to be 100% sure how many emails actually land in the inbox versus how many go to spam. This area could really use improvement. **What problems is WarmySender solving and how is that benefiting you?** WarmySender solves the email warm-up efficiently and offers an affordable alternative to other tools like Instantly. ### 4. All-in-One Cold Outreach with a Standout Lead Database **Rating:** 4.5/5.0 stars **Reviewed by:** Pranay S. | Founder, Small-Business (50 or fewer emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through Google One Tap using a business email account **Source: Organic:** Organic review. This review was written entirely without invitation or incentive from G2, a seller, or an affiliate. **Reviewed Date:** September 24, 2026 **What do you like best about WarmySender?** It covers the whole cold outreach process in one app: inbox campaigns, cold email, warm-up and a lead database. The lead database is what I've liked most so far. It's comprehensive, and the interface is very easy to use, so getting started was quick. **What do you dislike about WarmySender?** The cap of 33 per day on the Pro plan feels restrictive. It's also early days for me: I've watched the tutorial videos and started connecting my mailboxes, but I haven't run much volume yet, so I'll update this once I've used it more. **What problems is WarmySender solving and how is that benefiting you?** It replaces several separate tools for lead sourcing, warm-up and sending with one platform, which keeps my outreach setup simple and in one place. ### 5. Simple and Reliable Email Warm-Up Tool for Outreach **Rating:** 4.0/5.0 stars **Reviewed by:** Mukesh L. | Marketing Director, Creative Director, Small-Business (50 or fewer emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through a business email account **Source: Organic:** Organic review. This review was written entirely without invitation or incentive from G2, a seller, or an affiliate. **Reviewed Date:** September 15, 2026 **What do you like best about WarmySender?** WarmySender makes email warm-up relatively simple. Once the account is connected and configured, most of the activity can run automatically. I also find the reporting useful for keeping an eye on how the email accounts are performing instead of having to manually check everything. **What do you dislike about WarmySender?** The platform can feel a little overwhelming when you first start using it because there are quite a few settings and options. It would be useful to have more guidance around the recommended configuration for different types of outreach. **What problems is WarmySender solving and how is that benefiting you?** It helps us manage the email warm-up process for outreach accounts without having to handle the activity manually. This saves time and gives us a more consistent process when preparing accounts for outreach. ### 6. WarmySender: Easy to Use, Great Value, and Effective Email Warming **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) This reviewer's identity has been verified by our review moderation team. They have asked not to show their name, job title, or picture. **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through LinkedIn **Source: Organic:** Organic review. This review was written entirely without invitation or incentive from G2, a seller, or an affiliate. **Reviewed Date:** September 24, 2026 **What do you like best about WarmySender?** WarmySender is easy to use and offers very good value for money. I’ve been using it for more than five months, mainly for email warming, and it has worked well for my needs. **What do you dislike about WarmySender?** I’d like a bit more customization in the outreach campaigns, especially the ability to change or style the default “unsubscribe from this list” text. I’ve also noticed a few minor UI quirks occasionally, but overall they haven’t been a big issue. **What problems is WarmySender solving and how is that benefiting you?** WarmySender helps me keep my email accounts warmed up and ready for outreach without having to manage the process manually. After using it for more than five months, the warming has been reliable for what I need, and it saves me time compared with doing it myself. I also like having outreach tools in the same platform, since it lets me handle warming and run light campaigns in one place, all at a reasonable cost. ### 7. Highly Effective Email Warm-Up, Budget-Friendly **Rating:** 4.0/5.0 stars **Reviewed by:** Hash F. | CAESAR II Expert, Small-Business (50 or fewer emp.) **Validated Reviewer:** Validated through LinkedIn **Source: Organic:** Organic review. This review was written entirely without invitation or incentive from G2, a seller, or an affiliate. **Reviewed Date:** September 18, 2026 **What do you like best about WarmySender?** I use WarmySender for automated email warm-up and inbox deliverability management, ensuring cold outreach emails reliably hit the primary inbox rather than spam folders. The most valuable feature is the automated email warm-up engine, which actively pulls emails out of spam folders and helps train inbox providers to recognize my domain as trustworthy. I appreciate that it handles email warm-up, deliverability tracking, and cold outreach management all in one place. Additionally, WarmySender gives me the exact feature set I need, especially for robust deliverability and warm-up tracking, at a much better price point compared to Instantly. The initial setup was pretty smooth and straightforward, taking only a few minutes to connect mailboxes and kick off the warm-up process. Overall, I'd rate it 8 out of 10 as a solid, budget-friendly tool, though occasional billing quirks could be improved. **What do you dislike about WarmySender?** Billing hiccups and card renewals can sometimes be a bit fussy, and occasionally minor interface bugs pop up that require a quick reach-out to support. On the interface side, small glitches occasionally popup-like campaign alerts being a bit overly sensitive or dashboards taking a second to sync. To improve it, making the auto-renewal system smoother and fine-tuning the sensitivity on campaign pause triggers would make a huge difference. **What problems is WarmySender solving and how is that benefiting you?** WarmySender automates inbox warm-up and tracks domain health, keeping my cold emails out of spam and ensuring they land in primary inboxes. It saves me time and protects campaign deliverability effectively. ### 8. WarmySender: Seamless Cold Outreach and AI Assistance! **Rating:** 5.0/5.0 stars **Reviewed by:** Gary O. | Small-Business (50 or fewer emp.) **Validated Reviewer:** Validated through a business email account **Source: Organic:** Organic review. This review was written entirely without invitation or incentive from G2, a seller, or an affiliate. **Reviewed Date:** September 17, 2026 **What do you like best about WarmySender?** I appreciate the MCP feature in WarmySender that lets me operate mostly via the AI chat assistant. This approach aligns perfectly with my personal working style and I believe it's how people will work in the near future. The built-in email verification is like a subscription on its own, and the ease of use with the MCP is great. Quick and easy setup, along with the shared inbox, makes tracking simple. I love receiving daily scheduled updates in my AI assistant, which feels like having a team member who is consistently available. I prefer this workflow over others like Voila Norbert Email Sequences, especially with the MCP feature and email validation that made the transition worthwhile without any difficulties, thanks to the documentation and integration support. **What do you dislike about WarmySender?** If I could change one thing - I would polish the UI. **What problems is WarmySender solving and how is that benefiting you?** WarmySender solves the challenge and expense of cold outreach across multiple tools, offering built-in email verification and ease of use through MCP and AI assistant integration. It makes tracking and getting updates seamless with a shared inbox and feels like a daily reporting team member. ### 9. Promising, but too many bugs and errors **Rating:** 1.0/5.0 stars **Reviewed by:** Nat G. | Founder of iGlowly | Full-Stack Dev, Small-Business (50 or fewer emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through LinkedIn **Source: Organic:** Organic review. This review was written entirely without invitation or incentive from G2, a seller, or an affiliate. **Reviewed Date:** June 25, 2026 **What do you like best about WarmySender?** Warming looks good and fully functional. The product has potential, but for cold outreach, reliability is essential, and I couldn't use and trust it enough for my campaigns. **What do you dislike about WarmySender?** I really wanted to like WarmySender because the idea behind the product is great, but I experienced too many bugs to rely on it for production outreach. In the end, I lost around 1.5 days of my campaign because of technical issues. Campaign creation would sometimes fail with a "cannot create campaign" error, and when it did, my work was lost. I was later told drafts were auto-saved, but that wasn't my experience. Campaigns also showed as "Running" while sending zero emails, sometimes for hours and once for an entire day. Since there was no clear indication that sending had stopped, I only realized it later. I also had several Gmail mailboxes randomly disconnect, along with SMTP timeout errors that suggested my credentials were invalid. Support later explained that the issue wasn't on my side. Auto correction didnt work, so I removed them from my account. The biggest problem was the inbox synchronization. Replies from interested prospects didn't appear in the unified inbox, so I had to check all of my Gmail accounts manually. I only discovered several leads days later because of this. ANd this is a real damage. They fixed it later, but not sure if it does work now, as I left them finally. Bounce detection also didn't work correctly at first, so I had to update bounced contacts manually. To be fair, support was responsive and genuinely tried to help. They fixed several issues during our conversations and were always polite. Unfortunately, new problems kept appearing, and after losing valuable outreach time, I decided to move to another platform. **What problems is WarmySender solving and how is that benefiting you?** I warmed up 9 inboxes, then used them for the email campaigns. ### 10. Comprehensive Outreach Solution with Intuitive Setup **Rating:** 5.0/5.0 stars **Reviewed by:** Usama S. | CEO, Small-Business (50 or fewer emp.) **Validated Reviewer:** Validated through a business email account added to their profile **Source: Organic:** Organic review. This review was written entirely without invitation or incentive from G2, a seller, or an affiliate. **Reviewed Date:** September 04, 2026 At G2, we prefer fresh reviews and we like to follow up with reviewers. They may not have updated their review text, but have updated their review. **What do you like best about WarmySender?** I really like using WarmySender for my development agency's lead generation campaigns. The email warm-up and deliverability are very strong, which is crucial for our outreach. What I find most valuable is having everything in one place—email, LinkedIn, Instagram, and WhatsApp. It integrates smoothly, allowing us to start with email and gradually reach out to the same lead across different platforms, which I noticed improves our closing rate. The price is fair, and having all these features in one tool saves us from juggling multiple tools. Plus, the initial setup was very easy, making it a hassle-free switch from the previous tools I used like Instantly. **What do you dislike about WarmySender?** I think WarmySender could improve its lead data. It seems like they have the same data as Apollo, which has been used by many companies already. I would like to see data on new leads or businesses that aren't publicly available yet because their emails aren't always exposed on the internet. **What problems is WarmySender solving and how is that benefiting you?** I use WarmySender for multi-channel outreach, integrating email, LinkedIn, Instagram, and WhatsApp to improve our lead generation campaign. Its strong email deliverability enhances our communication effectiveness, and consolidating these tools saves costs compared to using multiple platforms. ### 11. Affordable Cold Email Help, But the Workflow and CSV Uploads Feel Cumbersome **Rating:** 3.5/5.0 stars **Reviewed by:** Paul M. | Owner, Small-Business (50 or fewer emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through a business email account added to their profile **Source: Organic:** Organic review. This review was written entirely without invitation or incentive from G2, a seller, or an affiliate. **Reviewed Date:** September 26, 2026 **What do you like best about WarmySender?** It was low-cost and has been able to help me with cold emails, as well as warming up my inbox. **What do you dislike about WarmySender?** It feels a bit cumbersome, with a lot of extra places I have to go just to get things done. Also, when I upload a CSV, it has to include the exact number per day to verify emails, rather than letting me upload one long list that it can keep pulling from each day to verify new emails. **What problems is WarmySender solving and how is that benefiting you?** Cold email sending process. ### 12. Intuitive Interface and Automated Warmup **Rating:** 4.0/5.0 stars **Reviewed by:** Christophe H. | Founder, Small-Business (50 or fewer emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** This review contains authentic analysis and has been reviewed by our team **Source: Organic:** Organic review. This review was written entirely without invitation or incentive from G2, a seller, or an affiliate. **Reviewed Date:** September 04, 2026 **What do you like best about WarmySender?** The interface is intuitive, and having automated domain warmup combined with an integrated leads database saves both time and setup costs. It keeps the cold outreach workflow simple and centralized without juggling multiple tools. **What do you dislike about WarmySender?** As an evolving tool, more deep analytics and granular reporting options over time would be great additions, but the core features work as expected. **What problems is WarmySender solving and how is that benefiting you?** It simplifies outbound infrastructure setup for new projects, ensuring good deliverability from day one while eliminating the need for separate warmup and data scraping subscriptions. ### 13. Great Mailbox Warmup and Clean UI **Rating:** 4.0/5.0 stars **Reviewed by:** Suraj K. | Digital Marketer, Small-Business (50 or fewer emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through LinkedIn **Source: Organic:** Organic review.

They are also accounting for user reviews and improving the platform, so that's a plus. **What do you dislike about WarmySender?** On the basic plan, they currently offer 1,000 leads, but it’s spread out over 30 days, and any unused portion doesn’t carry forward. **What problems is WarmySender solving and how is that benefiting you?** Prospecting, mailbox warm-up, and outreach across multiple channels for prospecting and acquisition. ### 14. Warmy Sender: Simple, Easy to Use, and Gets the Job Done **Rating:** 5.0/5.0 stars **Reviewed by:** Emod V. | Director of Marketing, Small-Business (50 or fewer emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through LinkedIn **Source: Organic:** Organic review.

It's cost-effective, saving me money while performing effectively. ### 16. Unbeatable Multichannel Outreach with Easy Setup **Rating:** 5.0/5.0 stars **Reviewed by:** Altaf M. | Media Success Manager, Small-Business (50 or fewer emp.) **Validated Reviewer:** Validated through LinkedIn **Source: Organic:** Organic review. This review was written entirely without invitation or incentive from G2, a seller, or an affiliate. **Reviewed Date:** March 30, 2026 **What do you like best about WarmySender?** I have used WarmySender, and it helped me to warm up my email and run a successful campaign. The LinkedIn outreach feature is fantastic and the part I like the most. I got connected with many professionals, which helped get good business. The pricing is unbeatable with these duo features. The Email and LinkedIn warmup and outreach wasn't available under one tool until I found this. The campaign creation and account linking process is super easy—just add the audiences and you're good. The ratio of sending connection requests feels natural, like a real human is doing the job. The multichannel warmup under one tool and the pricing plans attracted me. A non-professional can set up a campaign in easy steps. It's super easy to set up with unbeatable pricing plans. **What do you dislike about WarmySender?** The campaign creation flow should be improved and the stats after the campaign launch should be upgraded to showcase the real numbers. **What problems is WarmySender solving and how is that benefiting you?** I use WarmySender to warm up my emails and run successful campaigns. It combines Email and LinkedIn warmup tools, making outreach easy and effective. The pricing is unbeatable, and it helped me connect with professionals and grow my business. ### 17.

This review was written entirely without invitation or incentive from G2, a seller, or an affiliate. **Reviewed Date:** April 27, 2026 **What do you like best about WarmySender?** I like WarmySender's pricing because it's very affordable; you can get a lot of things for about $9 per month. This is great because many competitors are quite expensive, offering more or less the same features. It allows me to try it without breaking the bank. Additionally, I find the setup quite easy; you just need to sign up, which makes moving forward simple. Overall, with the pricing they have offered, it's a good deal, and they are pushing out regular updates. **What do you dislike about WarmySender?** Actually, the UI UX is still new. We can definitely improve that one as well. **What problems is WarmySender solving and how is that benefiting you?** I use WarmySender to get leads and send out cold emails to my prospects. ### 20.

The improved deliverability is amazing, helping my business grow. ### 21.
