You can use an existing domain, or register a new one. Pigeon currently only supports new email domains, but we will be enabling email migration from your existing mail host or mail server very soon.
Pigeon currently supports AWS EC2. We will be adding Digital Ocean, Google Cloud, and Linode in Q1 2017. With many more hosting options to come!
Pigeon will launch and configure a custom mail server for you, and all you'll have to do is update a few DNS records. We will walk you through every step.
Once it's all done, we will show you how to connect your new mail server to the desktop and/or mobile mail client of your choosing with IMAP. And that's it!
