Resend
Sends app emails, such as confirmations and receipts, from your own domain.
What it is
Resend sends the emails your app triggers, such as sign-up confirmations, password resets and receipts, through a simple API. You verify your own domain with DNS records (SPF, DKIM and DMARC) so emails arrive from your address and avoid spam folders.
Good for
- Early apps: the free plan covers 3,000 emails a month
- Developers who want a straightforward email API
Watch out for
- The free plan also caps you at 100 emails a day, so a burst of sign-ups or resets can fail
- Domain verification needs DNS access, so plan it before launch
