Description

Grade your sending domain's email authentication and get the exact DNS records to fix it.

Since 2024 Gmail, Yahoo and Outlook filter or reject mail from domains without SPF, DKIM and a DMARC policy, and Shopify will not send from your own domain until DMARC exists. A3E Sender Check reads those records the way mailbox providers do, grades them A to F, and lists every problem with the record type, host and value to add at your domain host. Daily re-checks and email alerts tell you when a record breaks. It reads DNS only; nothing on your store or DNS is changed.
