Please be aware that we levy a one-time $15 per domain fee when replacing domains. This amount goes toward registering the new domain once the old one(s) is deleted.
You can buy and register new domains on this page https://app.maildoso.com/billing/packages-addons (select only the domain slider)
IF you are here for SURBL blacklisting, you do not need to replace your domain at all, click below or go to the SURBL article for more information on why!
Note: replacing a domain ($15) is different from transferring a domain out to your own registrar — see Transferring your domains out of Maildoso.
