The automated DNS settings are great since our domains last 2 or 3 times longer, which addresses domains burnout. I have 80 active mailboxes that send about 17-20 emails each, totaling around 30,000 emails a month, and our placement rates are strong, close to 95% on testing. It's also nice that they push updates often, showing that they are actively improving things instead of just leaving it as is.

Our reply rate is around 3-5% in a competitive B2B SaaS niche, and the API integration with Instantly was seamless, connecting mailboxes with just one click. I also appreciate the savings on domain registration, which is just $12 for a .com, and there’s no need to stress over manually writing MX and SPF records. The initial setup was pretty smooth as well. **What do you dislike about maildoso?** There were a couple of delays with activating new workspace accounts. The site said 2 hours but it actually took until the end of the day. Their response rate needs to be improved. **What problems is maildoso solving and how is that benefiting you?** I use Maildoso for cold outreach, sending campaigns with links without hurting deliverability.

The transition of moving 120 mailboxes was smooth, with no breakage. What stands out to me is not having to manually set up DNS for every domain, as it's automated, saving a lot of time. This automation allows us to spin up new domains faster. Additionally, the pricing is noticeably cheaper than our previous provider, and the initial setup was straightforward. **What do you dislike about maildoso?** Support can sometimes make you nervous.

It allows me to add links like Calendly or Loom to the first email without worrying about landing in the spam folder, providing more confidence when sending campaigns. The IP reputation is very high quality compared to what you get elsewhere, effectively stopping the 'spam folder' trap. The initial setup was pretty well, and overall, I'm extremely likely to recommend maildoso to a friend or colleague. **What do you dislike about maildoso?** I wish there was an audit log to see what my other team members changed. Maybe just more visibility into how the tracking is performing would be nice, like simple stats. **What problems is maildoso solving and how is that benefiting you?** I use maildoso to send campaigns with links like Calendly or Loom without worrying about spam.

Effortless Deliverability for Agencies **Rating:** 5.0/5.0 stars **Reviewed by:** Fredrick C. | Vice President of Technology, Management Consulting, Mid-Market (51-1000 emp.) **Reviewed Date:** April 22, 2026 **What do you like best about maildoso?** I appreciate that with Maildoso, I no longer need a dedicated technical person to maintain our email servers as everything runs on autopilot. We switched to their combo package (SMTP + GW), and it really helped with deliverability; most emails actually land now, around 90-95% from what we see. It's very convenient to buy domains directly in the dashboard, and the initial setup was straightforward, which made the transition smooth. **What do you dislike about maildoso?** Some of my domains got blacklisted after the first campaign, but they replaced them for me with new ones. I think the main thing would be better prevention or early warnings, like some kind of alert if a domain is at risk before it actually gets blacklisted. **What problems is maildoso solving and how is that benefiting you?** Maildoso automates our email outreach, eliminates the need for a dedicated tech person, and significantly improves email deliverability (90-95%). It's convenient to buy domains directly from the dashboard. ### 7.

It allowed us to double our outbound volume this quarter without doubling our infrastructure spend, solving the scaling costs issue. We are sending nearly 45k emails a month across 150 boxes, and the uptime is solid without any mass suspensions. The cost is predictable, averaging about $2 per mailbox, which makes planning a lot easier as scaling up doesn't come with surprises. The initial setup was pretty straightforward. **What do you dislike about maildoso?** There's no mobile app. I'd like to be able to check domain health while I'm away from my computer. It's mostly about quick access. Sometimes you just want to check the domain or mailbox health when you're not at your desk. **What problems is maildoso solving and how is that benefiting you?** I use Maildoso to double our outbound email volume without increasing our infrastructure costs. The uptime is solid, and costs per mailbox are predictable, making scaling easier without financial surprises. ### 8.

The initial setup was pretty smooth, and that's definitely a plus for me. **What do you dislike about maildoso?** I had an issue connecting via Bluemail. I eventually found the answer in the docs myself. **What problems is maildoso solving and how is that benefiting you?** I use maildoso for cold outreach, which helps diversify risk by not being dependent on just one provider like Google.

Effortless Scaling with Maildoso's Reliable Setup **Rating:** 5.0/5.0 stars **Reviewed by:** Yulia K. | Chief Business Development Officer at Stfalcon, Manufacturing, Mid-Market (51-1000 emp.) **Reviewed Date:** April 13, 2026 **What do you like best about maildoso?** I use Maildoso for running cold email outreach at scale, and I really like that I can manage multiple mailboxes and keep everything authenticated, which allows me to send campaigns without dealing with setup issues each time. The setup feels like reliable infrastructure that keeps our operations moving smoothly. One feature I appreciate is the ability to bring our domains and connect them, making scaling a lot easier without being locked into anything. The setup is fast too, as I managed to get 40 accounts live and authenticated in under 10 minutes.

Cost-Effective Scaling with Effortless Integration **Rating:** 5.0/5.0 stars **Reviewed by:** Michael B. | Founder/CEO, Program Development, Mid-Market (51-1000 emp.) **Reviewed Date:** March 25, 2026 **What do you like best about maildoso?** I really appreciate that Maildoso is built for scale. We run about 400 mailboxes through it, and the cost savings we get compared to Google Workspace or Microsoft 365 are huge. The one-click integration with our sequencer made getting started very easy. The SMTP setup makes it easy to handle large volumes without things breaking, so I don't have to worry too much about managing individual mailboxes. **What do you dislike about maildoso?** There's no built-in warm-up tool anymore, so you have to rely on an external service for that. It's not a huge issue, but it does add one more step to manage. It would be better if they added a simple built-in warm-up feature again, even something basic. Right now, switching between tools makes the process a bit fragmented. **What problems is maildoso solving and how is that benefiting you?** I use Maildoso to lower costs and scale email outreach. Managing 400 mailboxes, I send 50k-70k emails monthly without budget increases. The SMTP setup simplifies large volumes, with one-click integration easing the startup process. - [View maildoso pricing details and edition comparison](https://www.g2.com/products/maildoso/reviews/maildoso-review-10404518?query=SPF&via=Bojan§ion=pricing&secure%5Bexpires_at%5D=2026-05-13+14%3A08%3A03+-0500&secure%5Bsession_id%5D=bdb1e2f8-a969-4850-a600-ad619f979b87&secure%5Btoken%5D=dd593ac78470a21f6e0a6174c8c0d2cb03e19851fe22b5e03fb2ed64292ab2a1&format=llm_user) ## maildoso Integrations - [Corporate Finance Institute](https://www.g2.com/products/corporate-finance-institute/reviews) - [Instantly](https://www.g2.com/products/instantly/reviews) - [lemlist](https://www.g2.com/products/lemlist/reviews) - [Microsoft Outlook](https://www.g2.com/products/microsoft-outlook/reviews) - [Smartlead](https://www.g2.com/products/smartlead/reviews) ## maildoso Features **Email Marketing** - Email and Mobile Preview - Manage Email Lists - High-Volume Sending - Building and Personalizing Emails - Sending Outbound Emails - Manage Email Deliverability - Automated Email Responses - Multi-user Account - Surveys **Reporting & Analytics** - A/B Testing - Basic Reporting **Generative AI** - AI Text Generation - AI Text Summarization **Agentic AI - Email Marketing** - Autonomous Task Execution - Autonomous Task Execution - Multi-step Planning - Cross-system Integration - Cross-system Integration **Integration** - Data Import & Export Tools - Integration APIs - Breadth of Partner Applications - CRM Integration - Social Media Integration - E-Commerce Integration ## Top maildoso Alternatives - [Instantly](https://www.g2.com/products/instantly/reviews) - 4.8/5.0 (4,075 reviews) - [Mailforge](https://www.g2.com/products/salesforge-mailforge/reviews) - 4.7/5.0 (85 reviews) - [Smartlead](https://www.g2.com/products/smartlead/reviews) - 4.5/5.0 (324 reviews)
