You can connect more than one mailbox to Rox and select the account used for sequence sending. Each mailbox has its own connection and sending limits. A mailbox can be connected to only one Rox user at a time. You can connect accounts from both Gmail and Outlook. ### Connect an additional mailbox 1. Open **Sequences** and select a sequence. 2. Open **Settings**, then the **Mailbox** dropdown. 3. Select **Manage mailboxes**. 4. Choose the option to add a Gmail or Outlook account. 5. Review the restricted-domain and initial-sync options. Restricted domains control which emails are excluded from processing. The initial-sync period determines how far back Rox reads email during the first sync. 6. Complete the provider's authorization flow using the correct Google or Microsoft account. 7. Return to the sequence and select the mailbox you want to use. ### Choose a mailbox for each sequence Adding a mailbox does not automatically change existing sequences. Review the **Mailbox** selection in each sequence's **Settings**. In a shared sequence, collaborators use their own connected mailboxes. They do not share a single sending address. ### Configure sending limits Open your mailbox’s **Deliverability settings** to configure **Number of emails per day** and **Delay between email sends (seconds)**. Your daily limit applies across all sequences using that mailbox. If your administrator has configured a workspace maximum, you can set your limit up to that maximum. If your previous setting exceeds it, Rox lowers your limit and displays a notice. New mailboxes and mailboxes without a user-set limit use the workspace default. **Emails sent today** shows your sent, scheduled, and remaining email counts. Select **Save** after making changes. For administrator controls, see **Sequence Sending Limits**.
### Select a tracking domain If your organization has configured custom tracking domains, select the appropriate one in the mailbox's **Deliverability** settings. Use a tracking subdomain associated with the sending address's domain. For example, a mailbox at `jane@example.com` would use a configured tracking subdomain such as `track.example.com`. See **Custom Tracking Domains** for the administrator setup process. ### Disconnecting a mailbox Before disconnecting a mailbox, review the sequences and conversations that use it. Follow-ups to contacts already emailed from that mailbox can fail after disconnection and may require you to reconnect the original mailbox. Do not assume that choosing another mailbox moves an existing email conversation to that account. Review affected contacts and scheduled messages before continuing outreach. ### Troubleshooting | Issue | What to check | | ---------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------- | | The wrong account appears during connection | Confirm which Google or Microsoft account is signed in before authorizing. | | A mailbox is already connected to another user | Each mailbox can belong to only one Rox user at a time. Resolve the existing connection before connecting it to another user. | | A sequence uses the wrong sending address | Review its **Mailbox** selection. Adding an account does not update existing sequences. | | Follow-ups fail after disconnection | Reconnect the original mailbox and review the affected contacts. |
