How to Use an Email Spam Checker to Keep Your Emails Out of Spam

An email spam checker is a tool that scans your outgoing emails for characteristics that might cause spam filters to block or divert them to recipients’ spam folders. It checks factors like subject lines, content, links, and technical settings such as SPF and DKIM authentication. Using an email spam checker helps small businesses ensure their emails reach prospects and customers reliably.

Why this comes up / what goes wrong

Small business owners often rely on email to communicate quotes, promotions, and follow-ups. However, if emails end up in spam folders, leads and customers may never see them, causing lost sales and wasted effort. Common causes include overly promotional language, broken links, missing authentication records, or sending emails to outdated lists. Without checking, businesses may not realize their emails are blocked or filtered.

Step-by-step

1. Choose a reputable email spam checker tool. Search online for free or paid tools that analyze email content and technical setup.

1. Prepare your email draft. Include your subject line, body text, links, and attachments as you intend to send it.

1. Enter your email content into the spam checker. Some tools let you paste the text or upload the email file.

1. Review the spam score and detailed report. Check for flagged issues like spammy words, broken links, or missing SPF/DKIM records.

1. Fix the issues identified. Rewrite subject lines, remove suspicious links, or update your domain’s email authentication settings.

1. Test again until your email scores well. A lower spam score means better chances of reaching the inbox.

1. Send a test email to different email providers (Gmail, Outlook, Yahoo). Confirm it lands in the inbox, not spam.

1. Monitor your email campaign’s open and reply rates. Adjust content and frequency based on results.

1. Use email automation and sequences to maintain timely follow-up. Automated follow-ups help keep prospects engaged without manual effort. See email automation and sequences for more.

Example (fictional figures)

A two-location dental practice in Columbus, Ohio, plans a promotional email about teeth whitening to 1,000 patients on 07/01/2026.

• They draft the email and run it through a spam checker.
• The spam score is 8/10, flagged for excessive exclamation marks and missing SPF record.
• They revise the subject line from "Get Bright Teeth Now!!!" to "Schedule Your Teeth Whitening Today".
• Their IT manager adds SPF and DKIM records to their domain.
• They retest the email and get a spam score of 2/10.
• They send the email and achieve a 25% open rate and 5% appointment bookings.

Calculation of expected appointments:

1,000 × 25% = 250 (opened emails)

250 × 5% = 12.5 ≈ 13 (appointments booked)

Common mistakes

• Ignoring technical email authentication (SPF, DKIM). Prevent by setting these records correctly in your domain DNS.
• Using spammy language or excessive punctuation. Prevent by writing clear, professional subject lines and content.
• Not testing emails before bulk sending. Prevent by always running emails through a spam checker and sending test emails.
• Sending to outdated or unverified email lists. Prevent by regularly cleaning your email list.
• Not monitoring email performance. Prevent by tracking open and reply rates to adjust strategy.
• Failing to automate follow-ups. Prevent by using sequences to maintain contact without delays. See email automation and sequences.
