Forward Zoho Mail (support@) to a Slack channel

Steps

1. 1

   Check your plan

   Zoho's forwarding page says new users who signed up on the Free plan don't get Email Forwarding, and adding outside members to a group needs a paid plan.

2. 2

   Add RelayMail as a forward

   In the Zoho Mail account that receives support@, go to Settings > Mail Accounts, select the address, and under Forwards enter the forwarding address from your RelayMail setup page (inbox-...@relay.relaymail.app). Leave "Delete original email copy after forwarding" unchecked to keep a copy in Zoho.

3. 3

   Enter the verification code

   Zoho emails a code to that address. RelayMail passes it on to the email on your Slack account. Back in Forwards, click the Verify icon, enter the code, click Confirm and save. Forwarding starts only after this.

4. 4

   Alias or group instead of a mailbox

   If support@ is an alias on someone's mailbox, use Settings > Filters > New Filter with a condition matching support@ and the "Forward to" action (verified the same way). If support@ is a group, add the RelayMail address as a member in the Admin Console and let everyone send to the group under Advanced Settings > Permissions.

5. 5

   Send a test email

   Email support@ from an outside account. When it arrives, RelayMail confirms forwarding by itself and the email appears in the channel as a thread; reply there and the sender gets your reply by email.

Confirming the forward

Zoho emails a verification code to every new forwarding address, and forwarding stays off until the code is entered (Resend sends a new one). Until forwarding is confirmed, RelayMail passes that email to the address on your Slack account. A group invites an outside member by email instead, and group mail reaches it only after the invite is accepted; that invite comes to you the same way. Replies you write in the Slack thread go out from noreply@relay.relaymail.app with Reply-To set to your support address, so the customer's answer comes back through the same forward into the same thread. To send replies as support@ itself, verify your domain in RelayMail (see the custom domain guide); that adds sending records for RelayMail and does not change where your inbound mail goes.

What to watch for

• Admins can turn forwarding off with a restriction (Admin Console > Restrictions > Configuring Email Forwarding). If the Forwards option is missing, ask the Zoho admin to check the restrictions on that user.
• If forwarding fails ten times in a row, Zoho switches it off automatically. Forwarding can't be turned on for POP accounts.
• Limits: a user can add up to 3 forwarding addresses and an admin up to 3 more. A filter can't forward to an address already listed under Forwards.
• For a group, the Permissions setting decides who can send to it; mail from anyone else is held for a moderator or bounced.
