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.

• Live SPF, DKIM and DMARC check of your sending domain, graded A to F
• Every problem comes with the exact DNS record to add, with copy buttons
• Daily automatic re-check with an email alert when a record breaks

From 27 September 2026, EU Directive 2024/825 bans generic environmental claims such as eco-friendly, green or sustainable, carbon neutral claims based on offsetting, and home-made eco labels in anything sold to EU consumers. Green Claims Checker reads your product titles, descriptions, SEO text, product types and tags in nine EU languages, flags each restricted claim by severity, and explains why it is a problem, how to reword it and which part of the law applies.

• Checks titles, descriptions, SEO text, product types and tags
• Each finding says why it breaks the rules, how to reword it, which clause
• Nine languages: English, German, French, Spanish, Italian, Dutch and more
• Works with Sidekick: ask which products to fix, or check new copy first
• Catches offset-based carbon neutral claims, vague eco claims, home-made labels
