About
SMTP Senpai is MailSenpai's EU-hosted SMTP relay and REST email API for password resets, order confirmations, notifications and website forms. Connect via SMTP on port 2525 or 587 with STARTTLS, the REST API, or a form endpoint for static sites. DKIM signing uses your verified sender domain, with SPF/DKIM/DMARC checks and automatic suppression of bounced addresses. The permanent free plan includes 5,000 emails per calendar month, up to 200 per day and 30 in the preceding hour, one verified sender domain and 7-day sending logs. No card or expiry. Paid annual plans start at EUR 12.90 per month plus VAT for 10,000 emails per month and 90-day logs. An email report is sent weekly on Monday. Official WordPress and Drupal plugins and open-source SDKs support integration. Written support is available in English and Italian. MailSenpai is the separate newsletter and email marketing platform.

About
Unitpost is an end-to-end customer communications platform.
You describe the workflow you want (a welcome series, shipping updates, a win-back campaign, etc.) and Unitpost builds it for you: ready to run across email, text, and WhatsApp.
Today we support transactional + marketing email with a hybrid template system (visual + code), contacts, segments, campaigns and automations. The foundation is built horizontally from day one: one contact model, one event system, one pricing model (shared sending balance), and every action works the same way in the UI, via API, and through our agent (Ask Unit).
We are not building another email tool. We are building the messaging layer that replaces the pile of tools teams currently stitch together and can be prompted for result, not manually built.
