Many businesses discover that their legitimate email is quietly landing in the recipient's spam folder, or being silently rejected by mailbox providers, without any bounce back. The usual cause is not the content of the email, it is a missing or broken authentication setup at the DNS layer. When SPF, DKIM, and DMARC records are absent, incomplete, or inconsistent across your sending sources, mailbox providers cannot verify that the email is really from you, so they treat it as suspicious.

This addon is a one-time fix that audits your domain's current authentication posture and implements the correct SPF, DKIM, and DMARC records for every sending source you use. That includes Google Workspace, Microsoft 365, your transactional email service, your CRM, your marketing platform, and any website form that sends mail on your behalf. Where SPF is too long or conflicts exist, we consolidate the record so it stays within the 10 lookup limit that mailbox providers enforce.

We then verify delivery using Google Postmaster Tools, set up if not already present, so you can see the real domain reputation, spam rate, and authentication pass rate that Gmail is measuring on your mail. A test message from each sending source is used to confirm SPF, DKIM, and DMARC alignment before we close the ticket.

The work is done by an engineer who has handled email authentication across hundreds of business domains, not by an automated wizard. You get a short report listing every record we added or corrected, the sending sources we authenticated, and the DMARC policy level we set (typically p=none for monitoring first, so nothing legitimate gets blocked while records propagate).

Buy this if your emails land in promotions or spam, if recipients complain they are not receiving your mail, if your DMARC reports show authentication failures, or if you are preparing to send at higher volume and want to lock down authentication before that traffic starts.
