Programmatic email forwarding with SRS
Catch-all and alias Routes that forward to any external address, webhook or inbox - created by API, unlimited domains, with SRS rewrite so SPF and DMARC survive the forward.
Catch-all and alias Routes
Forward *@your-domain to a mailbox, or route alias@your-domain to a webhook. Define it once via POST /v1/routes.
SRS keeps deliverability
Forwarding naturally breaks SPF. ThreadCamp rewrites the envelope sender (SRS) so the forwarded message still passes SPF and DMARC alignment at the destination.
Forward to code, not just mailboxes
Route to a webhook to trigger an agent, or into a ThreadCamp inbox to give an agent a thread to reply on.
This is part of ThreadCamp, the email API for AI agents: programmatic inboxes, Resend-compatible sending and forwarding Routes behind one key.

Questions
How does email forwarding work with SPF and DKIM?
A naive forward fails SPF because the forwarding server isn't authorised for the original domain. ThreadCamp applies SRS - rewriting the envelope sender to a domain it controls - so SPF passes and DMARC stays aligned.
Can I forward a whole domain (catch-all)?
Yes. Create a Route with match '*@your-domain.com' and an action of forward, webhook, inbox or split.
Give your agent an inbox in the next minute.
