#Connect Resend (BYOK)
Out of the box, notifications go through our shared sender, which sends up to 10 instant emails a day per account (the rest arrive in your daily digest). Add your own Resend API key and every notification goes through your Resend account instead: no daily cap from us, and it comes from your own domain.
- In Resend, go to Domains, add the domain you want to send from and add the DNS records it shows you. Wait until it says Verified.
- Go to API Keys → Create API Key. Choose Sending access (you can limit it to that one domain) and copy the key. It starts with
re_and Resend only shows it once. - In sendm8, open Account → Email, paste the key and click Save. We check it works straight away.
- Pick the From address, for example
forms@yourstudio.com, then send yourself a test.
Keys are encrypted before they’re stored and are never shown in full again: you’ll only see something like re_••••4f2a. To remove one, delete it in sendm8, and revoke it in Resend too for good measure.
