Newsletter hosting QA
Newsletter Web Version Checker
Scan email HTML or a hosted archive page for view-in-browser links, archive links, canonical tags, and titles before send.
HTML
Paste the email HTML or the hosted web-version page. Scanning stays in this browser.
HTML is processed locally. Links are not fetched and nothing is uploaded.
MissingWeb version checks
Results are heuristic signals for launch QA, not a live crawl of the hosted page.
Focused SEO checks
SEO tools turn a specific page, tag, or file into concrete output you can copy, validate, or preview.
Quick workflow
- Enter the target URL, metadata, or rule set.
- Generate or validate the SEO output.
- Copy the result and test related robots, sitemap, canonical, or social tags.
Useful tip
Work in a sequence: metadata, canonical, robots, sitemap, then social preview and schema markup.
