The power of Mailrun

Send 20,000+
emails per month

With our Growth plan, send 5 emails per day per inbox. Over 200 inboxes, and projecting 22 business days/month, that's more than 20,000 emails per month.

Fewer inboxes
per domain

Rather than connecting 99, 50, or 49 Azure inboxes per domain, we use just 10. By sending less volume per domain, Mailrun inboxes perform better and stay healthier longer.

Frequently Asked Questions

The Mailrun difference

If you have a question that isn't listed below, please reach out to us.

No, but we do offer flexible month-to-month pricing terms. If you're not satisfied for any reason, you can always cancel.

We will never charge an implementation or initiation fee.

Other providers know how incredibly effective Azure’s sending IP pools are—and they’ve used that as an opportunity to extract massive margins from hundreds of users.

In fact, many require you to schedule a sales call, only to make you wait days before pitching a four-figure initiation fee just for the privilege of using their service.

We’ll never do that. With Mailrun, just sign up, subscribe, and get your inboxes within hours.

No, we register domains for you, point the DNS records to Cloudflare, spin up email address permutations, and generate your CSVs. We've automated all of this from A-Z.

Other Azure email providers deploy anywhere from 49 to 99 inboxes per domain. As powerful as Azure is, we challenged ourselves to take it even further. When it comes to email deliverability, less is always more. While we can send just as many emails per inbox as other providers, the load on the domain is 80% to 90% lower than our competitors. That means Mailrun infrastructure performs better and stays healthier for longer. We're the only Azure email provider offering a setup this decentralized.

We think Microsoft Azure provides the best hard product in the game with respect to deliverability. Since it relies on Microsoft's enterprise-grade IPs, our infrastructure is even able to penetrate secure email gateways (SEGs) like Barracuda, Mimecast, etc.

Since we've automated domain registration and inbox creation, this is technically possible. And while other Azure providers tout this as a benefit unique to them, we discourage this practice. Domain age and email warmup still matter, so we recommend warming up your domains for at least two weeks.

I'm totally impressed by the Mailrun team. The inboxes are best in class, and their C-level is approachable for deep-dive support, even on the weekends!

Chris Keith

CEO, Hirexe

My experience with mailrun.ai has been really great so far. From even before I bought the mailboxes, Brian advised me on which package to choose then after I placed the order the support was amazing and I had the mailboxes on warm-up literally after 10 hours or so of purchasing. Then Brian was available to answer all of my questions to do with Smartlead specific settings. 10/10

Stef Moretti

Owner, Growth Agency

Mailrun has the best mailboxes I've used. They're built for performance and scale without issues, whether you're running 10 or 1,000. Their support team is also incredibly responsive when you need them.
