On the Email Users page, click the trash icon in the mailbox's Actions column and confirm with Delete. To delete several, tick them and click "Delete (N)" in the selection bar. Deletion runs in the background: the row disappears right away and the mailbox stops accepting logins shortly after. Messages stored in the mailbox are deleted with it. Warming on the mailbox stops and its charge ends from the next billing cycle. Pre-warmed marketplace mailboxes can't be deleted one by one.
When to delete
- The mailbox was for a campaign that's over.
- Someone left and you want the slot back.
- You're retiring a domain's mailboxes before deleting the domain.
If you only need a different address on the same domain, use Replace Usernames instead, which deletes and recreates in one step. If you only want to change the name recipients see, edit the display name.
What deletion doesn't do
- It doesn't delete the domain. The domain and its other mailboxes are untouched.
- It doesn't cancel your subscription. You're still billed for your plan.
- It doesn't reduce purchased mailbox credits. Lower those in Settings → Subscription if you no longer need them.
Alternatives to deletion
- Stop warming only: disable warming on the Warming page. The mailbox stays, the warming charge ends from the next cycle.
- Keep it idle: an unused mailbox costs nothing extra beyond its plan slot. Just remove it from your sending tool.

Frequently asked questions
Can I recover a deleted mailbox?
Winnr keeps a record of every deleted mailbox, including its address and password, so support can usually recreate it. The messages that were in it can't be recovered. Email support@winnr.app.
What about the messages in the mailbox?
They're deleted with the mailbox. If you need anything, copy it out with a mail client connected over IMAP before deleting.
Does deleting a mailbox free up a plan slot?
Yes. It no longer counts against your plan's mailbox limit, and you can create a new one in its place.
If I bought extra mailbox credits, does deleting reduce my bill?
Not automatically. Credits you bought stay on your subscription until you lower them in Settings → Subscription.
What if the mailbox has warming on?
Warming stops when the mailbox is deleted and the mailbox drops out of your warming charge from the next billing cycle. The current cycle isn't refunded automatically, but you can ask support for your most recent month back (see the [refund policy](/help/billing/refunds.html)).
Why can't I delete a pre-warmed mailbox?
Pre-warmed mailboxes are managed as a set with their domain. To remove them, cancel the pre-warmed domain. To change their addresses instead, use [Replace Usernames](/help/mailboxes/replace-usernames.html). Bulk deletes skip pre-warmed mailboxes and tell you how many were skipped.
Can the Winnr Agent delete mailboxes?
Yes. Ask the Winnr Agent in the chat panel. It lists exactly what will be deleted and waits for you to click Confirm.
