## About Sendaro

Sendaro is a transactional email API for sending password resets, receipts, sign-in links and notifications from your own domain. You verify a domain by publishing DKIM, SPF and DMARC DNS records, create an API key, and send with one REST request or an SDK call. A message ID is returned right away.

## About Supabase

Supabase gives you a Postgres database plus the pieces most apps need around it: authentication, row-level security, file storage, edge functions and realtime subscriptions.

The pitch is that you get a managed backend without leaving SQL behind, and can self-host the same stack if you outgrow the hosted version.
