Customer Reviews
Consistent, reliable service
I've been a Mailboxlayer customer for over a year now, mainly using their JSON API for real-time verification in a few apps. This last transaction for an annual subscription was as smooth as all the previous ones. The service is consistently reliable, catches most of the spam and typo issues, and the uptime is solid. That's why I keep coming back; it just works without fuss.
Email verification is a lifesaver
I can't believe how much easier my life is now with Mailboxlayer's Real-time Email Verification API! Integrating it was super straightforward, and it caught so many bogus emails right away. My bounce rates have dropped significantly. This service is incredible! I'm definitely subscribing again next year and recommending it to all my developer friends.
Good value, minor issue
I opted for a monthly subscription plan to use the Real-time Email Verification API and was generally pleased with the accuracy and speed. It significantly reduced our invalid sign-ups. Integration was fairly well documented, though I had a small hiccup setting up the MX Record Lookup initially – the examples could be a bit clearer for non-experts. Value for money is good, especially compared to others I've tried. Customer service responded within a day when I had that integration question, which was fine. Overall, a solid tool.
Worked pretty well
I needed to clean up an old email list for a project, so I gave Mailboxlayer's Bulk Email Verification a shot. It was easy enough to upload my list, and the results came back faster than I expected. It caught a bunch of disposable emails, which was neat. Pretty good overall experience, nothing to complain about.
Quick email check
Used Mailboxlayer for a quick syntax check. It worked. API was fast. Simple integration. Got what I needed. Satisfied with the service.

Is Mailboxlayer actually good? Seen some mixed reviews compared to ZeroBounce, trying to decide which to go with for a new project.
Hey, thinking of signing up. Do they have any deals going on right now for new users?
What happens if I go over my monthly API calls? Does it just stop working or do they charge extra?
Are their paid plans worth it over the free tier? Like how much better is the accuracy, specifically for catching temporary emails?
