# Multiple Mailboxes

Rox supports connecting multiple email accounts so you can send sequences from more than one mailbox, useful for managing separate sending identities, warming up new domains, or distributing volume across addresses.

### Adding a Second Mailbox

Once your first mailbox is connected, you can add additional mailboxes from the same Settings tab.

1. Go to Sequences → Select a Sequence (or create a new one) → Settings → click the dropdown next to Mailbox.
2. Select “Manage mailboxes”.
3. The mailbox modal shows your currently connected accounts plus options to add Gmail or Outlook.
4. Add any additional requirements around restricted domains (emails not to be pulled into Rox to process) and initial sync days (time range from which to pull in emails for initial processing).
5. Click through the authentication process.
6. Select the mailbox you want to use in your sequence!

Note that multiple users cannot add the same mailbox to their Rox account. Each mailbox can only be added to one user’s Rox account at a time. Additionally, each mailbox you add goes through the same OAuth flow, so make sure you’re signed into the correct Google or Microsoft account before authorizing.<br>

### Managing Mailboxes Across Sequences

Each sequence sends from the mailbox selected in its Settings. Adding a second mailbox doesn’t automatically apply it to existing sequences. You’ll need to update each sequence’s Settings to switch or add a sending address.

### FAQ

**Can I connect both Gmail and Outlook at the same time?**

Yes. You can connect multiple accounts from either provider.

**What happens if I disconnect a mailbox mid-sequence?**

Sequences configured to send using that mailbox will automatically fallback to using your primary mailbox instead. Any contacts in that sequence which have already received emails from your disconnected mailbox will fail to send subsequent emails. You must reconnect the mailbox to recover.

**Can different reps use different mailboxes within the same shared sequence?**

Each collaborator sends from their own connected mailbox. They’re not sharing a single sending address.

**Where do I set my daily send limits per mailbox?**

Via "Manage Mailboxes" from a certain sequence's Settings tab → Deliverability. Limits apply at the mailbox level.

**What is the best practice with custom tracking domains and multiple mailboxes?**

For optimal domain protection, your tracking domain should match the domain of any email address you connect. For example, if your admin has set up both [`trk.acme.org`](http://trk.acme.org) and [`trk.acme-corp.org`](http://trk.acme-corp.org) , and you are integrating your email [`jane@acme-corp.org`](mailto:jane@acme-corp.org), you should configure [`trk.acme-corp.org`](http://trk.acme-corp.org) as its tracking domain from Deliverability settings.
