Adding a custom sending domain

Without a custom sending domain, your campaigns send from [email protected]. Adding your own domain (e.g. [email protected]) improves deliverability, brand consistency, and gets your name into recipients' inboxes instead of "via turtini.com".

How it works:
We register your domain with Resend (our email infrastructure), which returns a set of DNS records you need to add to your domain's DNS provider. Once those records are in place and verified, the domain becomes available as a sender in the campaign composer.

To add a domain:
1. Go to Builder → Emails → Sending Domains tab
2. Click "+ Add sending domain"
3. Enter the domain (e.g. youragency.com or send.youragency.com — a subdomain works fine and is often easier to configure)
4. Pick a default local-part for the sender address (e.g. "hello" gives you [email protected])
5. Click "Add domain" — the system shows you the DNS records that need to be added

DNS records you'll see:
• TXT record for SPF — authorizes our mail servers to send on your domain's behalf
• TXT record(s) for DKIM — cryptographic signature so receiving servers can verify the message wasn't tampered with
• TXT record for DMARC — tells receivers what to do with mail that fails SPF or DKIM
• Sometimes an MX record for bounce handling

Add those records in your DNS provider, then click "Verify". Resend re-checks DNS and updates the status to Verified (or back to Pending / Failed). Verification can take a few minutes after you add the records.

Once verified, the address appears in the composer's "From email" dropdown for every campaign in your org.
