How to add or manage mailboxes in Unify
Last updated: February 23, 2026
Mailboxes in Unify are used for sending outbound emails and are essential for your email campaigns. Here's how to add, manage, and understand mailbox pricing.
Adding New Mailboxes
To add new mailboxes to your account:
Contact your account manager or support team to request additional mailboxes
Specify how many mailboxes you need and which team members they should be assigned to
New mailboxes require a 3-week warming period before they can be used for sending
Mailbox Pricing
Additional mailboxes cost $25 per mailbox per month. This pricing applies to new Gmail-managed mailboxes, which offer better deliverability than legacy Unify-managed mailboxes.
Reassigning Existing Mailboxes
If you want to change the name on existing mailboxes instead of purchasing new ones:
This process takes 1-2 weeks to complete
All existing enrollments on those mailboxes must be cancelled or reassigned
Mailboxes will be temporarily disconnected from Unify during the transition
An additional 1 week of warming is required after the name change
Viewing Your Current Mailboxes
You can view all your current mailboxes in Unify by going to Settings > Deliverability > Mailboxes.
Email Volume Guidelines
Each mailbox can send approximately 25 emails per day, so:
8 mailboxes = ~4,000 emails per month
20 mailboxes = ~10,000 emails per month
60 mailboxes = ~1,500 emails per day
Domain Recommendations
For optimal deliverability, Unify recommends a maximum of 5 mailboxes per domain to prevent being flagged as spam. If you need more mailboxes, consider setting up additional domains.
Note: Gmail-managed mailboxes (with Gmail logo) offer 4-8x better deliverability compared to legacy Unify-managed mailboxes and are the recommended option for new setups.
