Like most specialized hosts, GridPane doesn't support email. For those of you migrating to GP from a shared hosting environment, you may need to transfer your emails from your shared account to a dedicated email provider such as GSuite, Outlook or MXRoute. Luckily there's a great, free tool that makes this quick and easy. Check out the video below for a full walkthrough.
