About the A3E Sender Check
A3E Sender Check helps you verify and fix email authentication for your sending domain. The app checks your SPF, DKIM and DMARC records just like Gmail, Yahoo and Outlook do, then grades them A to F so you know exactly where you stand.
Since 2024, major mailbox providers filter or reject emails from domains without proper authentication. Shopify won't even send from your domain until DMARC is set up correctly. This app reads your DNS records and shows every problem it finds, giving you the exact record type, host and value to add at your domain host.
Each issue comes with copy buttons to make fixes easier. The app runs daily automatic re-checks and sends email alerts when a record breaks, so you can fix problems before they affect email delivery. It only reads DNS records and doesn't change anything on your store or domain.
Launched: September 25, 2026
