What the email & domain check reads
One free scan covers all six categories; this page puts Email & domain first.
- SPF and DMARCThe records that tell inboxes your emails are really from you.
- Your domain can receive emailAn MX record, so replies and receipts reach you.
- HTTPS everywhere, and wwwhttp:// moves visitors to https://, and both yourapp.com and www.yourapp.com work.
- RenewalsYour domain’s expiry date, your certificate’s renewal, and DNS that lets the certificate renew.
- Your own domainYour app runs on a domain you own, not only on a builder address.
Why it matters
Without SPF and DMARC, mail from a new domain often lands in spam. An expired domain or certificate takes the whole app offline at once.
Guides
Plain-English fixes with sources, from Pewterkit Guides.
- No SPF record found: add one SPF record for your domain
- No DMARC record found: add one at _dmarc, start with p=none
- Emails from a new domain going to spam: authenticate first, then build up slowly
- HTTP not redirecting to HTTPS: send every visitor to the HTTPS address
- www not working, but the domain without www does (or the other way around)
- Check when your SSL certificate expires, and whether renewal is working
