Only verified recipients appear in the picker, which is what stops an internal thread reaching a typo.
- 1Whitelist a recipient, once
An admin adds
[email protected]on the Powers → Email page. Viably emails a verification link to that address, and after one click they are permanently whitelisted. - 2React with the envelope on any message
Viably opens a small picker showing the whitelisted recipients available. Choose one or several, then confirm.
- 3The thread is sent as a clean email
Viably formats the entire thread, including message text, replies, and image attachments, into a single email sent from your workspace's branded sender address.
- 4Or ask Via in chat
In @Via AI, say “email this thread to [email protected] and [email protected]”. Same delivery with no menus, which helps when you are already in a Via conversation.
Verify a recipient once
Verification protects your team from accidentally sending out internal threads to emails you did not intend, or to unverified addresses that might be typos like [email protected]. This also helps protect our domain reputation, so your emails arrive cleanly in the recipient's inbox. Each address must click a one-time link before it can receive any forwards.
- Pending addresses stay marked
pendinguntil the recipient verifies. - Verification links do not expire, and re-adding an address sends a fresh one.
- Admins can remove entries at any time from the dashboard.
Trust your whole company domain
If you want every employee at your org to receive forwards without per-address verification, email [email protected] and we will add your domain. After that, any address ending in @yourdomain.com is implicitly allowed.
Trusted domains are checked by Viably staff so a public mail provider such as gmail.com cannot be added by accident. There is no self-serve write path.
- Only members of a channel can forward from it, and Viably never reads private channels it has not been added to.
- Every forward is logged, so admins can audit who sent what and where.
- Images are uploaded to private storage and referenced through signed URLs that expire, while the email itself carries a permanent inline copy.
- Disable the power entirely from Powers → Email if you want to switch it off temporarily.
A pasted thread loses the attachments, the ordering, and who said what, and it takes minutes each time. One reaction sends the whole thing formatted, from your workspace's branded sender address, so it reads like something your company sent.
Only verified addresses. An admin adds the address, the recipient clicks a one-time link, and after that it is permanently available. This is what stops an internal thread reaching a typo like [email protected].
Ask Viably to trust your company domain and every address ending in it is allowed without per-address verification. Trusted domains are reviewed by staff so public mail providers cannot be added by accident.
Yes. The same verified addresses and trusted domains authorise copying somebody on a reply from the Contacts workspace, so configuring this once covers both.
Whitelist your first recipient from the Email power page, and forwarding a thread afterwards takes one reaction.
