Features

Everything your
emails need

🔥
Smart Warmup Engine
Our algorithm mirrors human email behavior — real opens, real replies, real rescues from spam. Gmail and Outlook cannot tell the difference.
📡
Full SMTP Hosting
We become your email provider. Point your MX records to us and send through our warmed, reputed IP infrastructure. No more shared servers.
🛡️
SPF · DKIM · DMARC
Authentication configured automatically on setup. Every email you send is cryptographically signed and verifiable by receiving servers.
📊
Reputation Dashboard
Track your sender score, inbox placement rate, spam rate, and bounce rate in real time. Know exactly where you stand before you send.
🏢
Agency Mode
Manage unlimited client domains from one dashboard. Separate reputation tracking per domain. One bill, not per-mailbox pricing that bleeds your margins.
⚡
IMAP Access
Full IMAP access for hosted mailboxes. Use any email client — Apple Mail, Thunderbird, Outlook — with your MailBurn hosted domain.
Pricing

Simple. No surprises.

Flat monthly pricing. No per-mailbox fees. No usage limits that punish growth.
