What is Mailgenius and who is it for?
Mailgenius is a mail tester that checks your email deliverability and spam score.
Mailgenius is built for anyone sending marketing or transactional email who wants to make sure their messages land in inboxes and not spam folders.
That includes email marketers, small business owners, web developers, and agencies who manage client campaigns. It’s also helpful for IT teams or deliverability specialists who want to troubleshoot authentication or content issues before their emails go live.
Top Mailgenius features
Mailgenius comes with a solid feature set to help you stay out of the spam folder.
- SPF, DKIM and DMARC checks: Mailgenius tests your domain’s email authentication settings to confirm that SPF, DKIM, and DMARC records are correctly configured and aligned to prevent spoofing.
- Reverse DNS checks: This inbox placement test verifies that your sending IP address maps back to your domain name, which helps build trust with receiving mail servers.
- Domain age checks: Mailgenius checks how old your domain is, since newer domains are more likely to be flagged as suspicious by spam filters.
- HTML body best practice recommendations: The tool reviews your email’s HTML structure and flags issues like missing text versions, broken links, or excessive code that could trigger spam filters.
Mailgenius pricing
There are four plans available.
The Newbie plan is $8 per month, which gives you 10 monthly test credits and an AI deliverability consultant.
The Standard plan is $20 per month, and it unlocks 30 test credits, an official MailGenius, and the AI deliverability consultant.
The Genius plan is $39 per month, which gets you unlimited test credits per month and the ability to test your competitors’ emails. The Automatic plan is $79 monthly and it gives you just that, automated email testing.
