Free Email Spam Score Checker

How a Spam Score Checker Works

A spam score checker reviews your email message and looks for common signals that may reduce inbox placement. These signals include suspicious wording, overly promotional phrasing, missing balance between text and structure, risky formatting patterns, and content elements that trigger filtering systems like SpamAssassin and Barracuda.

This tool analyzes your subject line, from name, and email body against 15+ known spam triggers. It does not send your email — everything is processed instantly in the browser session. The goal is to identify issues before a campaign is sent, so you can fix them and improve your deliverability.

Spam Score vs. Email Validation — What's the Difference?

These are two separate problems that both affect whether your email reaches the inbox:

• Spam Score checks your content — the words, links, and formatting in your email. A high spam score means your email looks like spam to filters.
• Email Validation checks your recipient list — whether the email addresses actually exist. Sending to invalid addresses causes hard bounces that destroy your sender reputation.

You need both. Clean content + a clean list = maximum inbox placement. Validate your email list with Floy →

What to Do If Your Emails Keep Landing in Spam

If your spam score is low but emails still go to the spam folder, the problem is likely your domain or list quality:

• Check SPF, DKIM, and DMARC. Missing email authentication records are the #1 reason legitimate emails go to spam. Learn how to check your spam score →
• Validate your list. Sending to invalid addresses generates bounces that tank your domain reputation. Fix high bounce rates →
• Watch for catch-all domains. These accept your email but may silently discard it. Understand catch-all email risks →
• Warm up new domains. Don't send 5,000 emails on day one. Start with 20–50/day and increase gradually.
