SMTP Relay & Email API
Two ways in. Drop our SMTP credentials into any app, or call the Email API directly. Both take minutes, both just work.
Go from poor delivery to an inbox-hitting powerhouse by making the switch from SMTP.com to Maileroo. The best thing about this whole process? It is free and no credit card is required.
Maileroo includes everything in the plan. No add-ons to buy, pricing that stays affordable as you scale, and a dashboard you won't fight. Most users go from sign-up to sending in minutes.
Everyone else charges $30 to $80 a month for isolation from other senders' spam. Warmup schedule included, no sales call, no minimum volume.
Our /24 blocks are registered to Maileroo at RIPE, not leased from a host. Your dedicated IP has no history you inherit, and it stays with us wherever we run. View our RIPE org record
Over 35 mailbox providers, including Microsoft, Yahoo, Orange, Vodafone, GMX, WEB.DE and Fastmail, treat CSA senders as known rather than guessing.
SAML for your identity provider, roles per teammate, and API keys scoped to a single sending domain. Bring the whole team in without sharing one login.
Hard bounces, complaints and unsubscribes land in one suppression list, enforced at send time across every domain. Queryable and exportable over the API.
Every open, click, delivery and failure, plus the raw SMTP conversation. 14 days of retention, exportable to CSV or straight over the API whenever you want it.
Password resets can't wait. Neither can order confirmations, receipts, or anything else your users are staring at a blank inbox for. Our API is built for speed, takes minutes to wire up, and tracks every message from the moment you hand it over to the moment it lands.
We have training tools ready for everyone to read, and this can be your guide to using Maileroo. Our expert-vetted team is always ready to help out in case of any technical problems.
Our dashboard is simple. We make sure you'll be able to navigate Maileroo's dashboard with ease. We know how valuable every email is to your business. So, we make sure our SMTP services align with what you need.
Switch over to us, like the former SMTP.com users.
Hit a deliverability problem and you'll be talking to someone who has debugged it before. No tiered ticket queues, no bot asking you to restate the question. Live chat or email, answered by the people who actually run the platform.
Email delivery gets strange fast. A domain that worked yesterday, a Microsoft block with no explanation, a DKIM signature that validates everywhere except one provider. We deal with the same things you do.
Reviews are below if you'd rather hear it from customers than from us.
Send with confidence, track every message as it moves, and tune your performance. One platform, built developer-first. And deliverability? We fine-tune it obsessively behind the scenes, so your emails land where they should.

Two ways in. Drop our SMTP credentials into any app, or call the Email API directly. Both take minutes, both just work.

Sent, delivered, opened, clicked: watch every event the moment it happens. When something breaks, the logs tell you why.

Open rates, click rates, bounces, complaints. The numbers you need to sharpen your sending, all in one dashboard.

Push bounces, opens, clicks, and deliveries straight into your application the instant they happen. Your app stays in sync without polling.

Put tracking links on your own domain. Better brand consistency, better deliverability. SSL is provisioned for you, and setup takes one click.

We're a small team, which means when you write in, you're talking to someone who works on the product. Startups, agencies, and growing businesses stay with Maileroo because the support is real, the pricing is honest, and the infrastructure holds up.
"I love it as an SMTP service for transactional emails. The app is fast, easy to understand and fully featured, but not overwhelming, and email delivery is super fast and reliable. Just perfect! Every time I needed to request a feature or inquire about something with the team, they responded quickly and satisfactorily, both in their Discord channel and via email."

"I have been a Maileroo customer for almost 2 years now and I am very satisfied: Sending emails is super fast and reliable. The support is great and fast (usually within 1 hour). The interface is functional yet easy to use. You pay much less at Maileroo than at other providers without compromising on quality. In short, a great company to work with as an agency!"

"Using Maileroo for half a year now. Api and its documentation is simple, straightforward and just works. What truly makes the difference is the fast, personal support. Support is always quick to respond and to find a solution. Requests or suggestions are taken seriously and often translated into practical improvements. That level of personal involvement and service is rare and makes Maileroo a solution I can confidently recommend. Experience with mailgun, mailjet, sendgrid, resend and Maileroo takes the cake."
