Description

SMTP Senpai, offered by MailSenpai, serves as the SMTP relay for emails generated by your applications, websites, and tools, handling everything from sign-ups and password resets to order confirmations, notifications, and contact forms. You can connect using standard SMTP (port 2525 with STARTTLS), a REST API that provides JSON responses, or a dedicated form endpoint suitable for web forms, even on static sites. All outgoing emails are DKIM-signed using your own domain, for which we supply the necessary DNS records and verify them on your behalf. Automatically, we suppress bounced addresses, maintain a 90-day log of all sent emails, and provide you with a comprehensive weekly report. Rather than suspending your account upon exceeding a certain threshold, we issue a warning and guide you on what needs to be addressed. Our servers and data operations are based in the EU, and we offer support in both Italian and English through tickets and email. Try us out with a 14-day free trial that requires a card for registration (you can cancel anytime), and then continue with plans starting at €12.90 per month for up to 10,000 emails on an annual subscription. This service ensures reliable email delivery while offering flexibility and support for your communication needs.
