Overview
Maileroo is an email delivery service with an SMTP relay, a REST API with official SDKs, inbound routing, a template engine and an email verification API. It says it owns its IP space and vets each sender, and it publishes live time-to-inbox and delivery-rate figures on its home page.
The free plan is larger than most: 3,000 outbound and 1,000 inbound emails a month with all features. Paid plans start at $10 a month for 25,000 emails ($0.40 per 1,000) and fall to $0.25 per 1,000 at higher volumes. Plans of 250,000 emails or more include a dedicated IP at no extra charge.
Every plan includes click and open tracking, custom tracking domains, webhooks, blacklist monitoring, a mail-tester score checker and 14 days of full message retention. When you reach your monthly limit, a 12% buffer applies and then extra emails are dropped rather than billed, so watch the reminders.
