Connect a branded support mailbox - Sippet AI

Goal

Connect a branded support mailbox so your org can handle inbound and outbound support email inside Sippet.

Before you start

Choose the domain and inbox you want to use.
Decide whether the mailbox should default to the organisation, a user, or an AI agent.

Step 1: add the mailbox

In Settings > Emails & SMTP:

enter the inbound domain
review the MX target and listener values
choose the listener and TLS settings that fit your mail flow

Step 2: add sender identities

For each required address:

create the local-part and display name
choose the owner type
select whether it should be the default outbound identity

Step 3: test support handling

confirm inbound messages arrive
confirm the correct sender identity is used on outbound replies
confirm email activity appears in the contact’s support context

What good looks like

your support team uses branded outbound email
inbound mail is centralized
AI-assisted and human-led email flows share the same mailbox foundation
