Customer support is always unbelievably quick
When reporting problems to MailOptin support, I've found their turnaround time for fixing bugs and then releasing updates is fantastic. They are always brief, polite and professional in their messages.

Made cool things happen!
This simple but effective plugin helped me tie together my email systems and subscriber lists via wordpress in a way that allowed me to communicate with subscribers on a very occasional basis without having to maintain expensive mailer subscriptions like sendgrid or mailchimp. thanks. Great help.

Great solution to an annoying problem
I've been struggling with pop-ups, trying to get them to behave in a manner that is not oppressive to the website visitor. This one finally does that. It has the ability to show itself once and then remain silent for 30 days. Excellent.

Outstanding.
After trying IceGram and being tremendously disappointed, I decided to try MailOptIn. My stack includes WP Mail SMTP, MailOptIn, MailJet, and WP Forms. The implementation has been flawless and I love the ability to customize my forms and newsletters with such ease, and with zero issues. Well done MailOptIn.

Outstanding Customer Service!
One of the customer service reps contacted me and offered to create a free campaign for me! I just told him what I wanted, and he did all the work for me. And he did a great job!
