I love the ease of the pop-up form, and that would get 5 stars. Unfortunately, what makes this app problematic is how it imports all your customers from Shopify... it imports even the ones who have UNchecked to not receive marketing emails. There's no way to track that in Sumo. So I'm left having to manually manage this, manually deleting customers from Sumo who don't want marketing emails, and as I grow, this is going to become unmanageable.

I've been using this app for years, it has a lot of good points (simple to use, AB testing, integrations etc) BUT... it slows shopify down SO BADLY. Just do a GTmetrix review for your site if you install. It's crazy. Once they fix this I am happy to edit this review, it's such a shame as I do like this software (besides the fact that it is on the more expensive side)


If it weren't so unstable and unresponsive it would be a really promising app. But it blows my mind just how unreliable it can be. You just get the feeling it was rushed.


The mobile site for this is SO. FRUSTRATING. Also, if you could please develop a mobile app, everyone's life would be easier.

So far, (1 day into use) super simple to use and amazingly streamlined. Wish the cost per month was cheaper. will re evaluate rating as i use it more.

From where I am it looks like this will help in more ways than one, it looks like an email boom!!

Seems useful so far. I'm sure it will make collecting emails much easier for me.

I would like to see how it works first before I do A Review.


Program with really good potential. But you need to work a little bit more in the interface and dashboard. Sometimes is kind of slow too.

Maybe I gonna a try it later again.
