I Tested These 6 MXToolBox Alternatives to Boost Email Deliverability

MxToolbox is a popular tool for checking DNS, blacklists, and basic domain health.

But, many users reported issues that cannot be ignored:

• Slow or unhelpful customer support, especially for billing and cancellations
• High pricing for advanced features like inbox placement testing and multi-domain monitoring
• Inaccurate results in DKIM and SPF checks, requiring cross-verification
• Very limited free tier, as it allows only basic lookups
• Outdated UI and occasional glitches are slowing workflows

I’ve tested MxToolbox alongside other tools, and while it works for simple checks, it falls short for serious deliverability monitoring and campaign-driven outreach.

So, if you’re looking for MxToolbox alternatives that provide inbox placement insights, spam analysis, authentication checks, and actionable recommendations, you’re in the right place.

In this blog, I’m going to share the best alternatives to MXToolBox, which helps you protect your sender reputation and run campaigns in a better way.

1. Inbox Radar by Saleshandy

The first tool in our list is Inbox Radar by Saleshandy.

Why? I’ve three reasons:

• Inbox placement monitoring – goes beyond basic email authentication.
• Affordable – cost-effective plans for small and large teams.
• All-in-one AI-assisted platform – manage cold emails, deliverability, and insights without switching tools.

Inbox Radar shows where your emails land, explains why, and provides the tools to fix it, all in one place. It sends test emails to actual inboxes and tracks placement.

What you can do with Inbox Radar:

You get three types of tests.

• Recurring tests to automatically check inbox placement on a set schedule.

• External tests to check emails sent from outside Saleshandy.

Each test provides a detailed report on email delivery for the inbox, spam, and promotions. The report also shows you spam triggers, DNS/authentication (SPF, DKIM, DMARC), blacklist status, and content analysis. 

What do I like about these reports? You can even share your reports with your team through a public link.
