How to Use Mail Genius to Improve Email Deliverability & Avoid Spam

Getting your emails into your audience’s inbox—and not the dreaded spam folder—is a challenge many business owners and marketers face. No matter how great your content is, it won’t matter if your emails never get seen.

That’s where Mail Genius comes in. This free email testing tool evaluates your emails, identifies potential spam triggers, and provides actionable insights to improve deliverability. Instead of guessing why your emails aren’t reaching inboxes, Mail Genius scans your emails and gives you a clear report on what’s working and what needs fixing.

In this guide, we’ll walk through how to use Mail Genius, understand your email score, and make adjustments to boost your email deliverability.

Why Email Deliverability Matters

If your emails are landing in spam folders, it can hurt your open rates, decrease engagement, and negatively impact your sender reputation. Many factors determine whether an email makes it to an inbox, including:

  • Email content – Certain words and phrases can trigger spam filters.
  • Links & URLs – Too many links (or certain flagged URLs) can hurt deliverability.
  • Sender reputation – Your domain and IP address history play a role in whether emails get blocked.

Instead of manually troubleshooting these issues, Mail Genius does the work for you by scanning your emails and generating a deliverability score along with a detailed breakdown of potential issues.

Step 1: Visit Mail Genius & Test Your Email

To get started, head over to mailgenius.com. The website is straightforward and designed for one main purpose: testing your email deliverability.

On the homepage, you’ll see a test email address generated by Mail Genius. Copy this email address and use it to send a test email from your email marketing platform, CRM, or personal email account—whichever platform you are experiencing deliverability issues with.

For accurate results, send the same email you would typically send to your audience. Avoid modifying the subject line, content, or links, as Mail Genius needs to analyze your actual email structure.

Step 2: Analyze Your Email Score

Once you’ve sent the email, return to Mail Genius and check the box confirming that you’re not a robot. Then, click “See Your Score.”

Mail Genius will generate a deliverability score out of 100, providing a quick assessment of how well your email is likely to perform in terms of reaching inboxes. However, don’t focus solely on the number—what really matters is the detailed breakdown of factors affecting your deliverability.

Step 3: Review the Spam & Deliverability Report

The Mail Genius report highlights key elements that could be hurting your email deliverability. Some common factors include:

  • Too many links – Emails overloaded with links may trigger spam filters.
  • Blacklisted URLs – If your email contains a flagged or suspicious link, Mail Genius will notify you.
  • Spam-triggering words – Certain phrases (like “free money” or “guaranteed win”) may increase the chances of getting flagged as spam.
  • Missing authentication records – Issues with SPF, DKIM, or DMARC settings can impact sender reputation.

Each section of the report provides an explanation of why a specific factor is affecting deliverability and offers actionable steps to fix it. By clicking on each issue, you’ll see detailed guidance on how to resolve the problem.

Step 4: Make Adjustments & Retest Your Email

Once you’ve identified problem areas in your email, the next step is to fix those issues. Here are some common adjustments you might need to make:

  • Reduce the number of links – Too many links in your email can make it look suspicious to spam filters.
  • Avoid spammy language – Rewriting sections of your email to remove words or phrases that commonly trigger spam filters can help.
  • Check your domain authentication – Ensure that SPF, DKIM, and DMARC records are properly configured.
  • Use a verified email-sending domain – Avoid sending emails from free email services (like Gmail or Yahoo) if possible—use a custom domain instead.

After making changes, resend the email to the Mail Genius test email address and review your updated score. If necessary, repeat the process until you achieve a satisfactory deliverability rating.

Is Mail Genius Free?

Yes, Mail Genius offers a free tool for testing email deliverability. However, they also provide a paid subscription with additional features. While the free version is great for basic testing, the paid plan may offer more advanced insights and tracking tools for those who need deeper analysis.

At the time of writing, we do not currently use Mail Genius’ paid plan, but if you’re interested in learning more, visit app.mailgenius.com/pricing for details.
