Part 01 · Overview

Welcome

What it is, who it suits, its grades and the ten things to know first

2.6

GPA, above 34 of the 50 other email sending services we grade

Maileroo is an email delivery service that sends through an SMTP relay or a REST API, receives inbound mail and routes it to webhooks, and includes a sandbox for testing messages before they ship. Plans are priced by outbound volume, from a free tier of 3,000 emails a month up to 1 million, and every plan includes the same sending, receiving and testing features. Its pages say its servers sit in Germany, the Netherlands, Finland and France.

To get you started, here are 9 things to know about Maileroo, taken from its own pages and our grades.

You verify a sending domain with DNS records and wire up SMTP credentials or an API key before the first email goes out.

Maileroo is an SMTP relay and email API that also handles inbound mail and test inboxes, from $10 a month for 25,000 emails. The free plan has 3,000 outbound emails, but a dedicated IP starts at $72 a month and the price climbs fast after that.

Who Maileroo is for

  • Fits if you want to send and receive mail through one account
  • Works for developers who want test inboxes next to their sending

Who it is not for

  • Skip it if you need a dedicated IP below $72 a month, as lower plans use shared IPs
  • Tight if you stay free, with inbound capped at 1,000 and test emails at 100 a month
  • Watch out: prices on the page are monthly and no yearly option is shown
  • Watch out: Maileroo Verify is separate, at $0.03 per successful check plus the channel fee

Good to know

Good for

  • Developers who want SMTP and an API from one provider at a low monthly price
  • Teams that also need inbound email parsing and a place to test messages
  • Senders who prefer infrastructure hosted in Europe

Worth knowing

  • A dedicated IP starts at the Pro plan ($72 a month); lower plans send from shared IPs.
  • Prices on the page are monthly; no yearly billing option is shown.
  • The free plan caps inbound email at 1,000 a month and test emails at 100.
  • Maileroo Verify, a separate one-time-code service, costs $0.03 per successful verification plus the channel fee, billed from a prepaid balance.

Keep it, or make your own?

Whether this is something you could build for yourself with an AI app builder, and what you would give up.

Keep it

To replace Maileroo you would be making mail servers with a good name among inbox providers. That is not a weekend's work, with an AI app builder or without one.

It is one of the better ones too: its GPA of 2.6 is higher than 34 of the 50 other email sending services we grade. It costs $120 a year.

What you could not

  • Mail servers with a good name among inbox providers.
  • It plugs into other products, WordPress among them, and has an API.
  • The depth: we grade its features B, which means it covers the whole job.

What this rests on. Maileroo’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
