The 18-Person Empire Powering the Internet
How MXToolbox dominates DNS tools with $1.6M revenue and 2.8M monthly visits
While SaaS companies chase unicorn valuations with 200+ person teams, MXToolbox operates a $1.6M revenue machine with just 18 employees. This isn't a startup—it's a precision instrument that has quietly become the internet's plumbing inspector.
"They're not building a platform—they're building a utility. And utilities are stickier than platforms."
The Unsexy Moat
MXToolbox doesn't chase shiny objects. Their 2.8M monthly visits come from sysadmins and developers who need answers, not features. With 49% direct traffic, they've achieved what most SaaS companies dream of: becoming a daily habit. The 40% organic search traffic proves their SEO moat around 'dns checker' (352K monthly searches) and 'mx lookup' is nearly unassailable.
The Efficiency Playbook
At $88K revenue per employee, MXToolbox outperforms most tech companies. This isn't by accident—it's a deliberate focus on automation over headcount. Their tech stack (jQuery, Bootstrap, PWA) isn't cutting-edge, but it's battle-tested. They've traded Silicon Valley's 'move fast and break things' for 'move slow and never break.'
The 16.6M backlinks tell the real story. MXToolbox has become the default reference for DNS troubleshooting. When Stack Overflow threads, GitHub repos, and corporate wikis link to a tool, they're not just building traffic—they're building infrastructure. This is network effects in its purest form.
- Dominates 'dns checker' with 352K monthly searches despite minimal brand marketing
- 49% direct traffic suggests users bookmark and return—rare for utility tools
- Trustpilot rating of 3.7/5 from 18 reviews indicates reliability over delight
- Built on 18 technologies but runs like a single-purpose appliance
The Anti-Startup Startup
MXToolbox proves that boring infrastructure beats flashy innovation when you solve real problems for real users

Very good website
Very good website. We look for info and helped always. I give 5/5
I was able to use their service
I was able to use their service, and while it was helpful it turned out that I couldn't use it for a domain I didn't own. I was able to get a refund no problem and their customer service was friendly. Reading these reviews... They'll give you a refund in 30 days, but it's NOT a free trial... Maybe these people didn't read the site... who knows. I've been using MxToolbox for years for their free tools and if I need their services I will DEFINITELY use them.
Fantastic Experiences with Mxtoolbox, especially Brian Crawford Mxtoolbox has been fantastic with our…Fa
Mxtoolbox has been fantastic with our company's on and off again email delivery situations. In particular, we have worked with Brian Crawford. He is incredibly knowledgeable, kind, and patient which is not always easy considering the stressful feelings that come from clients with email issues. With a careful and analytic approach, he comes up with solutions for the underlying issues. Very, very good!
I use this tool every single day
I use this tool every single day - sometimes more than once a day. It's my GO TO for finding out DNS, Nameservers, MX servers, TXT whatever - it does it all. Their free stuff works great but for a little more money. you can have them help you fix DMARC and SPF/DKIM etc - they're very very good at DNS (better than me? YES) and fixing issues with delivery!
