How to Check Your Email Spam Score Before You Hit Send

You cleaned your list. No bounces. No catch-all risks. But your emails still land in the spam folder. Why? Because your spam score is too high.

Spam filters don't just check your email list — they scan your content, links, sender domain, and authentication before deciding: inbox or spam. Here's how to check your score and fix it before your next campaign.

1. What Is an Email Spam Score?

A spam score is a rating that predicts whether your email will be flagged as spam. It's calculated by spam filters (SpamAssassin, Barracuda, etc.) based on dozens of signals:

📝

Content Analysis

Spammy words ("FREE", "ACT NOW", "100%"), excessive caps, too many links, suspicious attachments, and broken HTML.
🔐

Authentication Check

Does your domain have SPF, DKIM, and DMARC configured? Missing records are a massive red flag for inbox providers.
🏠

Domain & IP Reputation

Has your sending domain or IP been blacklisted? Have previous campaigns from this domain generated spam complaints?
👥

Engagement Signals

Do people open and reply to your emails? Low engagement + high deletion rate = spam folder.

2. Spam Score Ranges Explained

Different tools use different scales, but here's what the numbers generally mean:

0–3

✅ Safe — Will likely reach the inbox

Your content and authentication look clean. No major red flags.

4–6

⚠️ Risky — May land in spam at some providers

Some triggers detected. Fix the issues before sending to a large list.

🛑 Danger — Almost certainly going to spam

Major red flags. Do not send. Fix content and authentication first.

3. The Big 3: SPF, DKIM, DMARC

The #1 reason legitimate emails go to spam is missing or broken email authentication. These three DNS records tell inbox providers that you are who you say you are:

Record	What It Does	Without It
SPF	Lists which IP addresses are allowed to send emails from your domain	Spam filters can't verify the sender → spam
DKIM	Adds a digital signature to your emails so providers know they weren't tampered with	No proof the email is authentic → spam
DMARC	Tells providers what to do if SPF or DKIM fails (reject, quarantine, or allow)	No policy = providers make their own decision → often spam

If you use Google Workspace, Outlook, or a cold email tool (like Lemlist or Instantly), they usually set up SPF and DKIM for you during onboarding. But always verify — one typo in your DNS record breaks everything.

4. How to Check Your Spam Score

Follow this checklist before every campaign:

1️⃣
Run your email through a spam checker. Paste your subject line and body into a tool like Floy's Spam Score Checker. It scans for content triggers and gives you a score in seconds.
2️⃣
Verify SPF, DKIM, and DMARC. Send a test email to mail-tester.com (free) or check your DNS records manually. Fix any failures.
3️⃣
Check domain and IP blacklists. Use a blacklist checker to see if your sending domain or IP has been flagged. If you're blacklisted, fix the root cause first.
4️⃣
Validate your email list. Even with a perfect spam score, sending to invalid addresses generates bounces that destroy your reputation. Validate your list first.
5️⃣
Send a test to a seed list. Mail a small batch across Gmail, Outlook, and Yahoo. Check if it lands in the inbox or spam before sending to your full list.

5. Common Spam Triggers to Avoid

Clean up these common mistakes and watch your spam score drop:

Trigger	Bad Example	Fix
Spammy words	"FREE", "GUARANTEED", "NO OBLIGATION"	Use natural language. Avoid all caps.
Excessive links	7+ links in a short email	Maximum 1–2 links per cold email.
Link shorteners	bit.ly, tinyurl.com	Use your full domain URL instead.
Misleading subject	"Re: Your inquiry" (when there was none)	Be honest. Use clear, relevant subjects.
Attachments	PDFs, ZIPs in cold emails	Host files online and link to them.
Missing unsubscribe	No way to opt out	Always include a visible unsubscribe link.
Image-heavy email	One big image, no text	Balance text and images (80/20 ratio).

6. Frequently Asked Questions

What is a good email spam score?

On most scoring systems (like SpamAssassin), a score of 0–3 is safe. Anything above 5 is risky. Some enterprise spam filters have stricter thresholds, so aim for the lowest score possible — ideally 0–1.

Why are my emails going to spam even with a low spam score?

Content is only one factor. If your domain or IP is blacklisted, your SPF/DKIM/DMARC is broken, or your engagement rate is low (people delete your emails without opening), inbox providers may still route you to spam — regardless of your content score.

Does my sending volume affect my spam score?

Yes. Sudden spikes in sending volume are a major red flag. If you normally send 50 emails/day and suddenly send 5,000, providers will be suspicious. Warm up new domains and inboxes gradually — start with 20–50 emails/day and increase by 10–20% per day.

How often should I check my spam score?

Before every new campaign, especially if you've changed your email template, subject line, or sending domain. It takes 30 seconds and can save you from a destroyed sender reputation.

Can I check my spam score for free?

Yes. Floy offers a free spam score checker that analyzes your email content and flags spam triggers. No sign-up required for basic checks. Try it now →
