Pros

Pros

“It was limited in that while yes, I built a pop up form, which was easy and user friendly, in which to capture leads, I didn't have a subscriber service already, nor was I interested in introducing an additional cost, so I back off of Optin.”

Beckie R.

Owner

“I love all the video tutorials they create for you, making it easy to repeat the process yourself.”

Yana H.

Product Marketing Manager

“It can be expensive compared to what you'll have to gain in return for your investments and secondly, for proper contact management, It's better to use MailChimp to handle contacts because optinMonster lacks a few functionalities that are essentially for handling managing subscribers.”

Cons

“I cancelled my subscription months ago and even had to get in touch with their team to cancel the direct debit which for some reason was set up twice, taking out a payment of £47+ every 2 weeks, turns out they are still taking the money and still haven't cancelled the direct debit on their end and are stil using and storing my bank details without permission”

Matthew S.

Director

“The biggest one is that it blows my mind the forms are not very mobile responsive.”

“I often have trouble customizing a display or getting it to display exactly when and where I want it.”
