Summary

Maileroo provides SMTP relay and Email API services for transactional and marketing email, with inbound routing and email testing tools. Sending features include sending streams, bounce and complaint handling, suppression handling and resending messages from logs. Inbound routing can apply custom expression rules, catch-all or wildcard matching, forward messages and send parsed JSON webhooks, with automatic retries, SPF and DKIM enforcement and spam checking. Testing includes SMTP and MX sinks, light and dark client previews, spam scoring, authentication and alignment checks, link and RBL checks, plus API and CI/CD access. Maileroo also offers click and open tracking, delivery event reporting, searchable activity, exports and real-time analytics. Listed integrations include SDKs for PHP, Laravel, Node.js, Python, .NET, Go and Java, as well as WordPress, WooCommerce, Zapier, Make and Pabbly. Security options include encrypted storage, two-factor authentication, passkeys, SAML SSO, scoped API keys, role-based permissions and IP restrictions. Monthly quotas and hourly sending limits apply; mail over the monthly quota is not sent until a reset or plan upgrade. A free plan is available; paid plans start at $10/mo.
