OptinMonster Reviews in September 2026: User Ratings, Pros & Cons

Great Product and Great Service

What do you like best? The analytics and customization for each campaign are so great. What do you dislike? Not a great setup for agencies. I am trying to work with 5-10 clients and there is not an agency portal for getting that set-up easily. Recommendations to others considering the product: I would recommend anyone considering running pop-ups on their site to consider Optin Monster. Extremely easy to set up and pretty intuitive to build out. What problems are you ...

I have been trying to create a website…

I have been trying to create a website for my company for the last 5 years and I didn't know how to start increasing online traffic and earn money in the process until I discovered Optinmonster! My hope is to use this tool to be able to reach my targeted audience with greater success than I would otherwise.

By Far The Best and Most Robust Plugin Technology for WordPress

What do you like best? I have been building websites for decades and have tried countless popup type plugins over the years. And I testify that OptinMonster is by far the best tool in its class. Their backend toolset is robust, simple to use, and works just as it claims. We've only been using it for a handful of months and can't say enough about the power behind it and how it helped us increase lead generation and onsite conversion for our customers. Their support is exceptional. I ...

Easily implement & test on-site popups

What do you like best? Built in A/B testing functionality allows for simple conversion tests. What do you dislike? I do not have a technical background, so I find it somewhat difficult to manipulate the design to get it to look exactly how I want it to. I wish there was a sort of drag-and-drop functionality. What problems are you solving with the product? What benefits have you realized? We are able to trigger on-site popups as well as popups on our external third-party ...

The worst popup platform ever.

The worst popup platform ever.Time delay don't even work. So many problems, and bad customer service.So many better alternatives.

Easy to use tool for marketing lead generation

What do you like best? The customization possibilities are very wide. You can customize the look and feel of your popups, forms and optins in many ways through colors, fonts, css and much more. Furthermore, the embedding process is very easy. It's integration with Hubspot helps us combine our lead acquisition efforts with our lead nurturing strategies by funnelling every lead into the correct nurturing path. It also helps us categorizing the lead in terms of interest, language and ...

Terrible company. Customer loyalty gets you nothing, but cancel and they'll offer you the world.

Great product. TERRIBLE customer service.We were an early user of OptinMonster, so when they changed all their plans and increased prices they kept us on a Legacy plan. However, we had a blunder and missed our annual renewal reminders as the notification email account was no longer active. As soon as we realised our account was suspended we logged in and tried to renew, however it wouldn't let us renew our previous Legacy plan. It was making us renew for double the cost with 3 websites ...

Spent five hours attempting to…

Spent five hours attempting to integrate Optinmonster and to no avail. Customer service appears to be incompetent. Suggested I call back in the morning. BEWARE!

Features & Instructions are Great!

Their features are very good. Furthermore, instructions on how to use any features are very easy to follow.

OptinMonster is a great service

What do you like best? Easy to use interface, colorful, click and drag. Good help center documentation, easy to understand instructions. What do you dislike? I wish there was a simple way to export analytics of a campaign to PDF so I can share with clients that don't have access to the interface. What problems are you solving with the product? What benefits have you realized? We use OIM so users on our platform can promote deals. Good conversation rates, nice looking pop-ups.
