One audit
1 pasted email
Use a single pasted message to run a broad pre-send audit without wiring a full send flow.
Free email audit
Free email audit tool for deliverability, HTML, and link checks
Run a free email audit before you send. Paste HTML or plain text to audit broken links, missing images, client compatibility, spelling, and HTML structure in one pre-send workflow. Use it as a fast email audit and HTML QA starting point, then pair it with sender-health monitoring when deliverability questions matter.
Run a free email audit
Paste one message and review the launch verdict
HTML produces the fullest result because link, image, compatibility, and HTML checks can all run together. Plain text still works when you want a fast content and link review.
Best fit
Use this before conversion-critical sends
This page is built for teams that need one practical answer before launch: does the message look ready, or are there defects worth fixing first?
- Audit onboarding, reset, billing, and campaign messages before send
- Catch broken links, missing images, and weak HTML before customers do
- Give marketing ops, lifecycle teams, and engineering one shared QA verdict
Upgrade path
Move from one-shot audits to repeatable workflows
The product workflow adds persistent audits, rendering checks, dedicated probe addresses, and operational ownership instead of relying on pasted one-off reviews.
- Create repeatable audits for recurring template streams
- Track drift after template refactors or ESP changes
- Escalate regressions with clearer ownership and history

Why this matters
A strong email audit should combine message quality signals, not scatter them
Searchers looking for an email audit tool usually want more than a narrow checker. They need one place to review link integrity, content quality, HTML validity, and client support before a customer-facing message ships.
Links
CTA safety
Verify that the URLs customers click are not broken, misrouted, or obviously risky.
Images
Asset readiness
Detect missing or broken images that damage trust and reduce response rates.
HTML
Markup quality
Catch structural problems that degrade rendering and create QA uncertainty.
Copy
Spelling review
Surface obvious content-quality issues before stakeholders or customers find them after send.
Operational use
Best used as the fast pre-send gate before deeper deliverability review
This free email audit helps teams decide whether the message itself is ready. Pair it with sender-domain checks when the underlying SPF, DKIM, DMARC, or inbox-placement posture also needs review.
Lifecycle email
Audit onboarding, activation, and retention flows before they quietly degrade the conversion path.
Transactional email
Use it before shipping password reset, receipts, and account alerts where broken links create immediate support load.
Campaign QA
Run the audit before scheduled campaigns, then use campaign probes for continuous QA across recurring send programs.

Open toolFAQ
What does this email audit tool check?
This free email audit combines broken-link checks, broken-image checks, spelling review, HTML validation, and email-client compatibility signals in one run. It is designed to answer the practical launch question: is this message ready to send?
How is this different from a campaign probe?
The public email audit is the broadest one-shot pre-send checklist on the site. Campaign probe is the follow-on workflow when you want a dedicated address, repeat runs, and ongoing QA for recurring campaigns or lifecycle streams.
Is this only for marketing campaigns?
No. Teams use email audits for onboarding, password reset, billing, receipts, alerts, and any other message where broken links, weak HTML, or compatibility regressions create customer risk.
Can this replace deliverability monitoring?
No. An email audit helps you review the message itself before send. Sender-domain posture still needs separate SPF, DKIM, DMARC, and domain health checks when delivery reliability matters.
