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.
Built for developers who want an all-in-one email platform that is easier to use, flexible enough to scale, and easier on the wallet. Switch to Maileroo and save up to 60% on your monthly email costs.
Tired of email platforms that feel like a pretty wrapper around AWS SES? Maileroo is built by people who live and breathe email. We run our own infrastructure, keep setup clear, and give you hands-on support whenever you need it. Created by developers for developers, Maileroo makes integration feel straightforward.
Plans start at $10 a month. We hold that price by running our own hardware instead of reselling AWS, so there is no middleman markup as your volume climbs.
Pass 250,000 emails a month and a dedicated IP is included, not upsold. Your reputation stays out of the shared pool and inbox placement holds steady.
Deliveries, opens, clicks, and bounces land in the log the moment they happen, searchable for 14 days. When something breaks, the event trail shows you why.
Drop in the SMTP credentials or call the API. Most apps send a first email in about five minutes, and the docs assume you have a backlog, not a free afternoon.
SMTP relay, REST API, inbound routing, webhooks, analytics, and suppression management live in one dashboard. You get a single view of every email without stitching separate tools together.
Restrict SMTP access by IP or domain and scope each credential to what it needs. The controls are built in, so tightening security never means a migration.
Pricing starts at $10 a month and stays flat as volume grows. Support is staffed by engineers who have shipped production email and read your logs before they reply.
Resend is a developer-first email API. Maileroo keeps email simple and affordable as you grow: send over SMTP or API, route inbound, run campaigns, track delivery, all from one place. When something breaks, a person answers.
Where Maileroo stands out. Sending, inbound routing, and campaigns on one platform, not three vendors stitched together. Plans start at $10/month against Resend's $20, with a free dedicated IP from 250k emails up. And we run our own network, so there's no big-tech cloud underneath.
Where Resend may fit better. If application email is all you need, its API and SDKs handle that cleanly. Teams already building with React Email will feel at home there too.
More capability, less complexity, and support that sticks around after you sign 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."
