WarmySender is an all-in-one cold outreach platform that combines LinkedIn outreach & automation, cold email sending, email warmup, email verifier, 20M+ B2B leads, and deliverability tools in a single workspace. Built for SDRs, founders, recruiters, lead generation agencies, and growth teams, WarmySender helps you run multichannel campaigns across LinkedIn and email, protect your sender reputation, and consistently land in the inbox instead of the spam folder. At the core of the platform is a unified Campaigns Hub where you can design multichannel sequences that blend LinkedIn touches — connection requests, profile views, follow-ups, and messages — with personalized cold email steps. Prospects, Leads, and Audiences tools let you organize your target accounts, import lists, segment by intent, and keep your pipeline clean and actionable. Reusable Templates, conditional logic, and automated sending schedules make it easy to launch outbound campaigns in minutes and scale them safely across multiple senders. Deliverability is treated as a first-class feature, not an afterthought. WarmySender includes a built-in Email Warmup engine that gradually trains your domain and mailbox reputation by exchanging natural conversations across a private warmup network, improving inbox placement over time. The new built-in Email Verifier validates addresses before sending to reduce bounces, protect sender reputation, and boost inbox placement. A real-time Mailboxes health view flags issues the moment something threatens sending — blocked mailboxes, authentication problems, or reputation drops — so you can fix them before they cost you replies. The Analytics dashboard gives a clear view of overall health across Email, LinkedIn, Warmup, and Campaigns, with metrics like total sent, open rate, reply rate, and delivery rate tracked week over week. A unified Inbox centralizes replies from every channel and mailbox so your team can respond quickly without juggling tools. Multi-workspace and admin controls support agencies and teams managing outreach for many clients or brands at once. WarmySender integrates with the mailboxes and accounts you already use and LinkedIn, and is designed to scale from a solo founder sending a few personalized emails a day to agencies running thousands of multichannel touches across dozens of senders. If you rely on cold email and LinkedIn outreach tools to fill your pipeline, WarmySender is the deliverability-first outreach platform that helps you send smarter, protect your reputation, and turn conversations into revenue.
