I found this in the Mailerlite integrations and it only took a few minutes to set up and run. I purchased this service once to clean a years-old subscriber list up, but plan on using it at least once a year with my current lists moving forward. Pros I used this in conjunction with my MailerLite account and it was effortless to work with as an integration. It definitely did clean my list up, as I saw a notable (positive) difference in my open rate after cleaning. Simple to integrate and very straightforward process and billing. Cons There honestly wasn't anything I found to be a hassle or troublesome. Review Source KB Katie B. Brand Manager Real Estate Used the software for: 2+ years ### "A must-have if you do any email marketing" April 4, 2024 5.0 Pros Mailercheck is so easy to use. The tool smoothly integrates into my Mailerlite email marketing tool. I love having a way to “clean” emails so I keep our domain reputation clean and clear making sure emails get delivered correctly in people’s inbox. Cons The only thing I would say is you gamble a little bit with the “catch-all” category as you don’t know if you are good to send or not. That is to be expected though. Review Source MB Margaret B. Executive Director Non-Profit Organization Management Used the software for: 1-2 years ### "Seamlessly Keeps Our Email List Clean" August 18, 2022 4.0 Pros Integrates easily with Mailerlite and allows us to check each each new email when added to the system so that our list is always clean. Cons We had a few issues where checking a large list timed out, however, tech support responded quickly and solved our issue. Very pleased with the outcome. Review Source LGP Luis G. P. Owner Marketing and Advertising Used the software for: 6-12 months ### "Works great for me" March 30, 2024 5.0 Works great, tested almost every feature. Pros Mailercheck has a nice credit system so I don't have to subscribe monthly to a service I might or might not use. The list cleaning system is great. It tells you syntax errors on the fly, also identifies possible catch all emails. The results are very well presented and are downloadable so you can categorize the results and act accordingly. Cons So far everything they have been aces with me. Sometimes the validation takes some minutes but I understand that has to do with DNS queries being performed or some sort of background check on the mail server. Review Source DC Divaldo C. CEO Consumer Services Used the software for: 6-12 months ### "Best email verification tool" January 7, 2023 5.0 I systematically send emails and some time ago I started to receive bouncbacks, I needed to check the list that I have had for a long time. Pros What I like the most is the fact that it works on credit and there is no need to pay monthly or associate a credit card. It's also quite simple to use that the first time you can already get an idea of the key features to have a validated email list. Cons I have no points to declare at this moment Review Source TB Ted B. Admin Non-Profit Organization Management Used the software for: Less than 6 months ### "New user satisfied" July 1, 2021 5.0 So far, using the sister MailerLite for campaigns has enhanced the delivery of email to our target audience. Pros The mail checking tool allows us to clean up as well as review our contact list. Cons I have not been using it long enough to make a coment.

It quickly checks all emails and then uploads the checked and approved ones straight to the account. Cons It is a little bit confusing at first but after trying it out you get the hang of it quickly Reason for choosing MailerCheck Integrates with Mailerlite Review Source MR Mohamed R.
