Adding a DKIM record

To create a DKIM record, you need to add a TXT record to your domain's DNS setup. The process of updating your DNS records may vary based on the DNS/ ESP or web hosting provider you have.

We've compiled a list of links to the documentation of popular providers in the table below. Please note, that this list is not exhaustive, and being included in this table is not an endorsement or recommendation of any particular company. If your provider is not listed, don't worry, you can still publish a DKIM record.
