How to add or modify mailboxes for your team

Last updated: March 23, 2026

There are two main ways to get mailboxes set up for new team members or modify existing ones: purchasing new mailboxes or reassigning existing mailboxes.

Options for Adding Mailboxes

Option 1: Purchase New Mailboxes

New mailboxes cost $25 per month per mailbox. To purchase new mailboxes, contact your account manager or support team with:

  • First and last name of the sender

  • Primary email address for forwarding replies

  • Number of mailboxes needed

New mailboxes require a 3-week warming period before they can be used for sending emails.

Option 2: Reassign Existing Mailboxes

You can transfer existing warmed mailboxes from one team member to another. This process involves:

  • Canceling or reassigning all existing enrollments on those mailboxes

  • Temporarily disconnecting them from Unify

  • Changing the names and rewarming for 1 additional week

Domain and Mailbox Limits

We typically maintain 6-10 mailboxes per domain for optimal deliverability. If you need more mailboxes, we'll spin up additional domains for you automatically - you don't need to worry about purchasing new domains.

We require .com domains and don't create email aliases (like hello@company.com or team@company.com) to ensure maximum deliverability.

Forwarding Setup

All mailbox replies can be forwarded to:

  • The mailbox owner's primary email

  • Another team member

  • Multiple email addresses (requires additional coordination)

Forwarding settings are easy to change later and don't require rewarming.

Important Notes

  • Even if someone won't be actively using the mailboxes, they should still accept the Unify platform invitation to ensure proper sender name variables work correctly

  • Mailboxes can only be used within Unify - they cannot be used for manual sending or other email platforms

  • When team members leave, their mailboxes can be reassigned to new hires with just a 1-week rewarming period

To get started with adding or modifying mailboxes, contact your account manager or Unify support team with your specific requirements.
