Set up authenticated email sending
Configure a custom sending domain and approved sender for production workflow email.
Open Account β Email Sending, complete the business profile, and add the domain you will use. Add the displayed DNS records at your DNS provider, then recheck verification.
After DNS verification, the domain may require separate Revup approval. Add and verify the sender mailbox, choose a default sender, and confirm the page shows the route as ready.
Send a test Flow email and review From, Reply-To, branding, links, unsubscribe, and delivery. Custom-domain sending can be unavailable when billing is inactive, DNS changes, approval is pending, or a provider hold applies.
