I've been using a custom email domain for my professional correspondence, but after my domain got transferred from Google Domains to Squarespace last year, I started experiencing issues. Recently, my emails have been getting blocked due to DMARC failures, and I haven't changed any of my DNS records. Can anyone explain what might be causing this issue and how DMARC works?

DMARC plays a crucial role in how mail servers handle emails that don't align with your SPF and DKIM records. If your emails aren't properly authenticated, they can end up being marked as spam or rejected altogether. It’s essential to implement these protocols gradually to ensure smooth operation.
DMARC is basically a protocol built on top of SPF and DKIM to enhance email security. It ensures not just that SPF checks out or that DKIM verifies, but also that both are aligned with the domain you're sending from. Many free email providers are now requiring senders to have DMARC set up to combat spam and impersonation. If you haven't configured DMARC for your domain, your emails could get blocked. It's definitely worth looking into setting it up.”,
You might want to check your DMARC record to see if it's correctly configured. A good site for that is mxtoolbox.com. Also, sending a test email to yourself and checking the headers can reveal a lot about what's going wrong.
For those who aren't tech-savvy, you can send an email to Gmail, then click the three dots next to reply to choose 'Show original'. This will display the SPF, DKIM, and DMARC results at the top!
Exactly! Also, make sure you get SPF and DKIM set up properly before turning on DMARC.
