What a rule does

A forwarding rule maps a localpart on your domain to a single destination email address: 
[email protected] → [email protected]
Mail to [email protected] is filtered, then re-sent to [email protected]. You can have many rules per domain (up to 200), and the same localpart can fan out to multiple destinations. Manage rules from Inbound → your domain → Forwarding in the Dashboard.

​
Adding rules

1

Open the Forwarding tab

Pick your forwarding domain in Inbound and switch to the Forwarding tab. If you don’t see it, the domain isn’t in forwarding mode. Change it on the Settings tab first.
2

Add an address

Under Forwarding rules, enter the localpart (e.g. support) and a destination (e.g. [email protected]), then Add rule. The destination has to be a bare email address, with no display names or quoted parts.
3

Verify the destination

The first time you send mail to a destination, the destination owner gets a confirmation email. Until they click the link, mail to that rule won’t be delivered. See Destination Verification.

​
Catch-all

A catch-all forwards every address on your domain that doesn’t match a specific rule. Without one, unmatched mail is rejected with 550. Add a catch-all from the Catch-all card on the Forwarding tab. You only need to provide a destination. Specific rules always take precedence over the catch-all, so [email protected] still hits its own rule even with a catch-all in place.

​
Plus-addressing

Plus-addressing matches automatically. A rule for support will also match: You don’t need a separate rule per suffix.

​
Pause, edit, delete

Each rule has three controls:
  • Pause / Resume: soft-disables a rule without deleting it. Paused rules behave as if they don’t exist (mail falls through to the catch-all or is rejected). Use this instead of deleting if you’ll re-enable later.
  • Edit: change the destination without losing the rule. The localpart is immutable; to rename, delete the rule and create a new one.
  • Delete: removes the rule. The destination row in your account stays around, so re-pointing another rule at the same address won’t trigger another verification email.

​
Limits

  • 200 rules per domain. The Forwarding tab shows a count / 200 badge that turns yellow at 180.
  • Localpart max 64 characters. Standard RFC 5321. Anything that’s a valid local-part is allowed except special characters that break SMTP routing.
  • Destinations must be bare addresses. [email protected], not Support Team <[email protected]>.
