Score your message for spam signals before you hit send
Spam filters judge your message in seconds. SpamCipher reads the email you are about to send, scores the content signals filters react to, and flags what might hold you back, so you can fix problems while you can still change them.
Check your message
See what filters see, before they see it
Filters do not work off a fixed list of banned words. They weigh patterns, reputation, and how people engage. SpamCipher reads your message for the content signals that tip those decisions, and shows you what to fix.
- Paste or upload your email. Drop in the subject, body, and links, or upload the full message, and SpamCipher reads it.
- We score the content. Each part of the message is checked against the signals filters react to, with nothing sent to anyone.
- Fix the flags and recheck. Get a clear list of issues with plain advice, make your edits, and run it again.
- Text and image balance: flags image-only emails with little text
- Link quality: spots shorteners, mismatched and low-reputation domains
- Missing alt text: catches images with no fallback wording
- Subject line patterns: flags all-caps and misleading phrasing
- Authentication and from-address: the signals that matter most for trust

Sending a campaign you never checked?
It is not too late to look. If you have a message ready to go that you have not scored, run it through SpamCipher first. You will see exactly which content signals are working for you and which ones could hold the message back.
You fix what stands out, keep your subject and layout honest, and send knowing the content is not quietly working against you.
Want to check every message automatically? Use the API
Score the content of every message before it leaves your system. The SpamCipher API reads a single email and returns its content score in moments.
Wire it into your sending platform, campaign tool, or workflow, with a clean response your team can act on or block on.
Pre-send scoring keeps weak content from ever reaching your audience, without anyone checking by hand.
Explore the APIHow to get the most from your content score
A low score is a good sign, but it is not the whole story. Authentication and sender reputation carry more weight than any single phrase, so set up your from-address and records properly first, then treat the content flags as the finishing pass that keeps your message clear and honest.
Make the check a habit, not a last-minute step. Score each campaign before it goes out, watch which patterns keep getting flagged, and your messages, your layout, and your standing with the inbox all move in the right direction.
