I handed an intern the initial creation, setup and use of the MailerCheck account and it was a breeze. The setup went smoothly and it only took a couple of hours to do everything until running the email verification.
I used this with my MailerLite account and it was effortless to work with. It definitely cleaned my list up, I saw a notable (positive) difference in my open rate after cleaning. Very straightforward process and billing.
I was introduced to MailerCheck by a friend of mine when I couldn't find a credible solution to help us verify our customer data. We're very conscious of our email marketing and sales email efforts and try to keep a tidy and up-to-date CRM. MailerCheck is a vital part of this process and it's been so easy to onboard and use their solution on a regular basis to ensure high accuracy of email delivery with our campaign.
