Custom domain email for agents and apps, via API
Add your domain, get the full MX/SPF/DKIM/DMARC record set, verify, and start creating addresses programmatically. ThreadCamp manages DKIM and DMARC alignment so mail from your agents lands.
Add a domain in one call
POST /v1/domains returns every DNS record you need - MX for receiving, SPF and a pair of DKIM CNAMEs for signing, and a DMARC policy. Place them at your DNS host and call verify.
One address, or a thousand
Once verified, mint inboxes on the domain via POST /v1/inboxes. Each is a real, addressable mailbox with threads, messages and forwarding - not just a sending identity.
Deliverability handled
We align SPF and DKIM automatically and forward with SRS so SPF survives the hop. No AWS console, no raw DNS spelunking.
This is part of ThreadCamp, the email API for AI agents: programmatic inboxes, Resend-compatible sending and forwarding Routes behind one key.

Questions
Can I use my own domain for agent email?
Yes. Add it via POST /v1/domains, place the returned MX/SPF/DKIM/DMARC records, verify, then create inboxes on it. Sending and receiving both work on custom domains from the Pro tier.
Does ThreadCamp set up DKIM and DMARC for me?
It returns the exact records and manages alignment. You place the records once; we handle signing and SRS on forwards so SPF/DMARC pass.
