# Will your email land in spam?

A free tool from Keres AI. Paste your subject and body. We’ll score the content for spam-filter risk and tell you exactly what to fix — all in your browser, nothing uploaded.

An **email spam score** estimates how likely your message is to be filtered, based on content signals — trigger words, ALL-CAPS, excessive links and punctuation, and promotional tone. This checker analyzes your copy and returns a score out of 100 with specific, fixable issues.

## What does a spam score measure?

Spam filters weigh many signals: who sent the message (authentication and domain reputation), how recipients have treated your past mail, and what the message itself contains. This tool scores only the last part, the words and formatting you can change before you hit send, so a clean score here does not guarantee the inbox if your domain is not authenticated.

## Which content patterns raise the score?

- **Pressure words** such as “act now”, “guaranteed” or “risk-free”, especially in the subject line.
- **Shouting:** long runs of capital letters and repeated exclamation marks.
- **Link-heavy bodies:** several links or link shorteners in a short message.
- **Money and urgency together:** prices, “free” and deadlines stacked in a short message.

## What should I check besides the content?

Run your sending domain through the [deliverability checker](https://www.keresai.com/tools/deliverability-checker) for SPF, DKIM and DMARC, warm new inboxes gradually (see [inbox warm-up](https://www.keresai.com/glossary/inbox-warmup)), and keep cold outreach on a separate domain. [Sol](https://www.keresai.com/agents/outbound) does this set-up before it sends anything.

## Spam-score checker FAQ

### What is an email spam score?

A spam score estimates how likely a message is to be filtered as spam based on its content — trigger words, formatting, links, and tone. This tool analyzes your subject and body and flags the patterns that hurt placement.

### Does a good spam score guarantee the inbox?

No. Content is only part of deliverability — authentication (SPF, DKIM, DMARC), sender reputation, and warmup matter just as much. Use this alongside the deliverability checker for a full picture.

### How do I lower my spam score?

Remove trigger phrases and ALL-CAPS, cut exclamation marks and extra links, keep the subject 30–50 characters, and write in plain, specific, personalized language instead of promotional copy.

### Is my email content sent anywhere?

No. This checker runs entirely in your browser — nothing you paste is uploaded or stored.
