About SMTP Senpai
SMTP Senpai is the SMTP relay by MailSenpai for the emails your apps, websites and tools send: sign-ups, password resets, order confirmations, notifications and contact forms.
Connect it via standard SMTP (port 2525, STARTTLS), a REST API with JSON responses, or a form endpoint for website forms, including static sites.
Emails are signed with DKIM on your own domain: we provide the DNS records and check them for you. Bounced addresses are suppressed automatically, every email stays in a 90-day sending log and you get a weekly report.
We don't suspend your account because a threshold was exceeded: you get a warning and we tell you what to fix.
Servers and data in the EU. Human support in Italian and English, by ticket and email.
14-day trial at €0 (card required, cancel anytime), then from €12.90/month for 10,000 emails on the annual plan.
