"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."

FAQ

FAQ For Agencies

Yes. Enterprise customers can connect their organisation's SAML system, so people in their organisation sign in to Maileroo through their existing identity provider.

You can use the Domain option to create isolated SMTP credentials or an API key for each client domain. The more versatile option is Applications: attach the domains you need, control which aliases can send, restrict which domains it can send to, set IP restrictions, and get dedicated SMTP and API credentials per application. That is the better fit for advanced setups that need more control and flexibility.

Paid plans include unlimited domains, so you can add every client domain you manage without hitting a cap or moving them onto separate accounts.

You get 14 days of email logs with advanced filtering, so you can search across every client domain and application and find the message you need without jumping between accounts.
