OptinMonster is one of the best lead generation tools on the market and pretty much works immediately out of the box. You can quickly get a campaign up and running, integrated with the tools you're already using. I like the large number of templates and the many customization options. This makes OptinMonster easy for beginners and a great tool for advanced marketers as well. The simple Wordpress integration is also a time-saver.

What I like the most is that OptinMonster is easy to use on every website you own. It works both on Wordpress websites and any other website you own. Either you use the WordPress-plugin or you just add a piece of code to your site to display your campaigns. You also get a lot of ready-made templates that are already optimized for high conversions. After being around for so many years and learning from customer campaign data, OptinMonster knows what works and is constantly improving their templates. This way you don't need to start from scratch and know something will work. All you need to do is browse the templates, pick one, customize it a little bit and then publish your campaign.

There's not much I dislike about OptinMonster. There are different plans that you can take depending on your specific needs, but one thing I'd like to see changed is the page view limitation that comes with each plan. Once your campaign is displayed a certain number of times per month, you will need to upgrade to a higher plan if you reached your maximum.

Optinmonster makes it very easy to put beautiful forms on your website and pop them when, where, and how you need them on your websites. They integrate with email marketing software platforms easily, and there is always Zapier if they don't happen to be integrated with the platform you use. I have been a customer for 3+ years, and despite the fact that I can better design forms, I still prefer to use them for my customer optin information collection. The many different ways you can have a form display on your website keep me as a customer.

I started using Optinmonster because I couldn't design a good looking form and I couldn't get it to open / pop when I wanted it to. I needed something that looked better than what I could get from my email marketing software and I needed to make it appear when and how I wanted it to. This is easily accomplished with Optinmonster!

They don't update their form designs very often and if you want to have the same form used on different pages or in different ways (on click vs exit intent) then you have to design a new form and set it up for each individual interaction scenario you need.

The ability to capture email addresses via the tools OptinMonster provides is great but the UI could use a functionality upgrade.

Once you finally get it up and running, the ability to create pop ups and exit intents and top bars is great. It works as expected and it's nice to be able to a/b test.

The UI is terrible - editing a template requires clicking around aimlessly hoping you'll hit on whatever it is you need to be able to edit what you're trying to edit. There is no internal analytics - it relies on a connection with GA, so if you don't turn that on, you get no data on how it's performing.

So many useful features. It's one of the few pieces of software where I use about 80-90% of it's features.

Optin Monster is a great, low-cost alternative to capturing leads on your website. The free version has a lot of what the average startup will need. And the pro version does some incredible things like A/B testing automatically. What I like is how simple it is to set up the landing pages, opt-ins, and thank you pages. I gave it to my clients to play with, and they were up and running with the software!

I don't really have any complaints with Optin monster. It works, there's frequent updates that makes the software better, and the free version is a excellent taste for many startups. Maybe one thing I don't like is the free version has the optin monster logo... but it's a free version for a reason.

Very pleased with Optin Monster. The customer service is truly outstanding. One time I was struggling making a custom form and they actually had someone do custom CSS and HTML for me! Was awesome

You could teach this software to someone who has never used a form builder in their life before. It is simple and easy to use. While also being very effective,

What I wish this software had is the ability to upload files to the forms. So people could submit files for specific pages and what not.
