Can AI Make Sure Your Emails Get Delivered?

If your email marketing campaigns aren’t performing, the problem might not be your content; it could be that your emails aren’t even reaching inboxes. Great copy and beautiful design don’t matter if your messages end up in the spam folder. While you can troubleshoot deliverability on your own, it’s time-consuming and technical. That’s where Mailgenius comes in.

What Is Mailgenius and Why Use It?

Mailgenius is a deliverability testing tool built to help businesses improve inbox placement. It’s designed for anyone who sends bulk emails—marketers, agencies, small business owners, or even IT teams. Before you send a campaign, Mailgenius checks your email for potential red flags so you can fix them and avoid spam filters.

What Does Mailgenius Offer?

This tool goes beyond a basic spam check. It evaluates several technical and content-related factors that influence whether your emails make it to the inbox, including:

• Authentication checks (SPF, DKIM, DMARC) – Ensures your domain is properly set up to prevent spoofing and phishing.

• Reverse DNS and domain age checks – Verifies your IP reputation and domain credibility.

• HTML structure review – Flags issues like broken links or missing plain-text versions that might trigger spam filters.

By running these tests, Mailgenius helps strengthen your sender reputation and increase the chances that your emails land where they belong—in the inbox.

Are There Alternatives?

Mailgenius is a solid choice for quick, detailed email checks, but if you need more comprehensive solutions, consider these options:

• Woodpecker – Offers inbox warm-up, automation, and spam checks all in one platform.

• Mailreach – Specializes in improving inbox placement for cold email campaigns.

• Mailtrap – Great for testing transactional emails before they go live.

• InboxAlly – Helps boost reputation through engagement simulation, ideal for large senders.

• Warmy – Provides advanced warm-up and analytics for high-volume outreach.

Bottom Line

Mailgenius is a helpful tool if you want to quickly test your emails and fix deliverability issues. However, if you’re looking for an all-in-one solution with automation and inbox warm-up, a platform like Woodpecker or Warmy might be a better fit.
