You can set up a personal email address (address@yourdomain.com) with all paid Jimdo Dolphin plans.
Requirements
If you've connected your own domain to your Dolphin website, you can use one of the following methods to set up your email address.
Forwarding address
A forwarding address, also called alias, is a pure forwarding of incoming emails. This email address does not have its own inbox, but will simply forward the messages on to a real email account.
Also, you won’t be able to answer from a forwarding address.
Google G Suite
Alternatively, you can use Google’s paid service G Suite to set up your email address with your domain.
