Migrate from Resend to PostStack

Why switch from Resend?

• Paid plans start at €5/month. Resend has no paid tier below $20
• Save up to 72% on your bill at the entry tier and around 21% at higher volumes
• IMAP and POP3 mailboxes, DMARC aggregate reports, and a visual email builder, none of which Resend ships
• EU data residency in Helsinki, Finland, not US data centers
• API-compatible SDKs and migration guides that let most teams cut over in under an hour
