A3E Sender Check

Gmail, Yahoo and Outlook send mail to spam, or reject it, when the sending domain has no SPF, DKIM or DMARC record. That can include your order confirmations. A3E Sender Check reads those DNS records the way mailbox providers do, grades them A to F, and lists each problem with the record type, host and value to add at your domain host. On the Pro plan it re-checks daily and emails you when a record breaks. It only reads public DNS; nothing in your store or your DNS is changed.
