Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureOrder confirmations and shipping updates are landing in spam or not arriving. Gmail, Yahoo and Outlook reject mail from domains without proper SPF, DKIM and DMARC records — one broken record is enough to lose the sale. A3E Sender Check reads your sending domain's DNS the way mailbox providers do, grades it A to F, and shows each problem with the exact record to add (type, host, value) to copy to your domain host.
SiteSaviour monitors key public storefront pages—without adding theme code. It checks home, cart, search, product, collection, policy, and custom URLs for HTTP errors, redirects, slow initial responses, missing expected text, incomplete HTML, insecure active resources, and notable page or script-host changes.
