Yes.
If you want to replace a mailbox, you may delete it and recreate it using the Add More Email Accounts option at the bottom of the Maildoso dashboard. After doing so, the new mailbox should be warmed up for at least 10 to 14 days.
Note: deleted mailboxes are not freed instantly, so recreating one with the exact same name right away can return an "already exists" error — wait a little, or contact support to clear the old one first.
If you want to replace a domain, a one-time fee of $12 per domain applies. Please contact support for assistance with domain replacement.
The in-app "delete & replace" gives an error
If replacing a domain from the dashboard (for example swapping a blacklisted domain using domain credits) throws an error and won't complete, this is a known issue with that flow — it's not something you've done wrong. Contact support with the domain(s) you want to replace and we'll action the replacement from our side. A short Loom or screenshot of the error helps us sort it out faster.
Downsizing your plan removes mailboxes automatically
When you downsize or downgrade your plan, the system removes mailboxes automatically to match the lower count. Right now you cannot choose which mailboxes or domain are kept, so a downsize can delete the ones you wanted and keep others. After a downsize you may also be unable to re-add the same domain from the dashboard (and you can't edit DNS yourself — we manage it).
If a downsize removed the wrong mailboxes or domain, contact support right away. We can often restore recently deleted mailboxes and re-enable the domain from the backend. Don't repurchase or recreate them blindly first — reach out and we'll sort it out.
