Vectis Mail vs Mailcow vs iRedMail vs Mail-in-a-Box — what's different?
All four are self-hosted email platforms targeting different operators.

Vectis Mail vs SendGrid vs Postmark — are these even comparable?
On the API surface, yes: sending API, inbound webhooks, analytics, domain-scoped keys all match. On the operational model, no. SendGrid and Postmark are managed SaaS billed per email; Vectis Mail is self-hosted on your own VPS, billed flat ($0 Starter / $29 USD Pro per tenant per month, unlimited volume). Cost crossover with Postmark sits around 30K emails/month. Vectis Mail also includes full IMAP/POP3 mailbox hosting; SendGrid and Postmark do not.
