Analyze the actual email
Scan receives the real message you send, including headers, authentication verdicts, links, HTML, and sending information instead of analyzing only pasted copy.
Deliverability scan
Run a real pre-send deliverability check
Send the exact email you plan to launch to a one-time Scan address and get a practical report covering authentication, sending infrastructure, blacklist signals, content, links, and other deliverability risks.
What CheckInbox Scan helps you verify
Scan analyzes a real received email sample and turns technical deliverability signals into a readable pre-send report.
SPF, DKIM and DMARC in one report
Review received-message authentication evidence, alignment, visible From identity, and available SPF, DKIM, and DMARC verdicts in one place.
Sender infrastructure diagnostics
Inspect sender IP, MX and A records, PTR and reverse DNS, forward-confirmed PTR, technical sender identity, and other infrastructure signals.
IP and domain blacklist signals
Check both IP and domain blacklist layers while avoiding false hard failures from resolver-limited or inconclusive responses.
Content, HTML and link analysis
Review subject quality, aggressive wording, capitalization, HTML-to-text balance, images, tracking pixels, links, shorteners, forms, and attachments.
Readable actions, not raw diagnostics
Get a practical score, delivery-critical status cards, findings, and recommendations designed to help operators understand what to fix first.
How to run a Scan
For the most representative result, test the final email through the same sender, domain, and sending platform you plan to use in production.
1
Generate a Scan address
Open Scan and create a one-time address for the email you want to analyze.
2
Prepare the exact campaign email
Keep the real From identity, subject, HTML, links, images, tracking, and other elements that will be present in the production campaign.
3
Send it through your real ESP
Use the same sending platform, domain, and infrastructure as the real campaign so authentication and infrastructure checks reflect the actual sending path.
4
Wait for automatic analysis
CheckInbox receives the message and automatically builds the deliverability report from the captured email sample.
5
Review critical checks first
Start with From alignment, SPF, DKIM, DMARC, IP and domain blacklists, reverse DNS, and unsubscribe signals before moving to deeper findings and recommendations.
Recommended usage
- Test the final campaign version, not an early draft. If you materially change links, HTML, sender, tracking, or domain setup, run Scan again.
- Always use the real sending path. A test sent manually from a personal mailbox does not represent a campaign sent through a different ESP or domain.
- Fix authentication and infrastructure problems before focusing on smaller cosmetic content changes.
- Use Scan together with Check: Scan helps explain what may be technically wrong, while Check shows where the email actually lands across monitoring inboxes.
Important to know
Scan is a practical pre-send diagnostic, not a guarantee of inbox placement. A technically healthy email can still land differently for real recipients because mailbox providers also consider sender and domain reputation, engagement history, sending volume, list quality, infrastructure consistency, and provider-specific filtering. Use Scan to identify fixable risks, then use Check to measure actual placement.
