This article covers the SPF and DKIM authentication processes for SiteGround and how they are managed in Valimail. While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.

Note: Even though their website suggests that SiteGround supports SPF and DKIM alignment for a custom domain, we have yet to see SPF and DKIM aligned emails on a custom domain for SiteGround.

The best way to make sure is to ask their support directly to see if they actually support SPF and DKIM alignment for a custom domain.

By default DKIM should be enabled. To disable DKIM for your domain, go to Site Tools > Email > Authentication > DKIM > Deactivate. To regenerate the DKIM record you can Deactivate and then Activate it again.

Once you establish that SiteGround is an authorized sender for your domain, you will need to add the service in your Enabled Senders.
