A3E Sender Check launched on September 25, 2026. Shoplist is watching for its first storefront installs and tracking pricing in the meantime.
Get alerted on first storefront installs, review spikes, pricing changes, and listing edits.
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.
Every number on this page comes from public storefront scans and the public Shopify App Store listing. If Shoplist shows A3E Sender Check on a store, it is there.
