There is no other Shopify app that checks email authentication the way MailMedic does, so the honest comparison is with the manual route: MXToolbox, a DMARC analyser and Shopify's own help pages. That route works. It also takes an hour, requires you to know what “v=spf1 include:shops.shopify.com” means, and tells you nothing about whether your Shopify sender domain is aligned. Here is what MailMedic does instead.
| MailMedic | Manual check with MXToolbox / DMARC analysers | |
|---|---|---|
| Price | Free for one domain · Pro $1.99/mo for more domains | Free web tools (paid tiers for monitoring) |
| Free | Full check of one domain, plain-language fixes | Individual record lookups |
| What is checked | SPF, DKIM, DMARC, Shopify sender alignment, MX, in one report | One record per lookup; you interpret the result |
| Fixes | Exact DNS record to add, per provider, copy-paste | Generic guidance, not Shopify-specific |
| Monitoring | Weekly re-checks with alerts (Pro) | Paid tiers on some tools |
| Access | Read-only: never touches DNS or the store | Public DNS only |

No. It only reads public records and Shopify's sender configuration. You make the change at your domain provider, with the record MailMedic gives you.
Shopify-managed domains are usually configured automatically. Run the free check anyway; it takes ten seconds and confirms it.
The check is cheap to run. Pro exists for agencies and multi-store owners who want several domains monitored.
Free for one domain. Read-only, nothing to break.
