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.
One scan. Three audits. Store Health checks your theme for security vulnerabilities, accessibility gaps, and SEO issues — then tells you exactly how to fix each one. Missing alt text? Flagged. No meta descriptions? Caught. Risky scripts? Detected. Every finding includes severity ratings and step-by-step fixes. Track your health score over time and watch it improve.
