Updated over a week ago

To help ensure your emails reach your customers' inboxes, you can set up custom DKIM authentication for your domain, and add Marsello to your SPF record.

Internet Service Providers (ISPs), like Google, Yahoo, and Microsoft, use DKIM and SPF authentication as a way to scan incoming emails for spam or spoofed addresses. Emails that fail authentication are more likely to arrive in a spam or junk folder.


Before you get started

Here are some key details to note about custom domains before getting started:

  • Custom domain authentication is optional for Marsello retailers

  • To set up authentication, you need to change some account settings with your DNS provider. If you don't know who your DNS provider is, reach out to your hosting service.

  • If you don't have a custom email domain yet, here are some useful resources on how to do this:

  • If you already have an SPF record for your domain. You would just need to add our lookup at the end of the string, before the ~all mechanism, like so:
