SPF/DKIM/DMARC
We always recommend verifying your domain when using EmailOctopus. If you've already verified your domain, then SPF/DKIM will already be set up.
If you send over 5,000 emails per day, you'll want to set up DMARC.
We're providing the record required here to all customers who haven't yet got this in place, and any new customers verifying their domain will be provided this during their domain set up.
