After downloading the app, I couldn't login and kept receiving a "You are not authorized for this site" error. Support was unhelpful and it makes me doubt that this app will work at all.

It's one of The most Stupid App I has ever seen don't use it
don't use it don't use it
don't use it
don't use it

Canceling this app is a PAIN! They don't let you do that through the website. They charge u $49/mo and the results are not worth it. Think twice before you start paying them.

I can't find out how to cancel my subscription, reduced the speed of the site and many other annoying things on this app...

lets me add plug in but then redirects customers to sumo website. only good if you pay for the service.

I had such high hopes for this but haven't seen good results. I have a blog post that generates thousands of visitors a month. I wanted Sumo to capture email address and sadly, after two months ($79/month x 2= $158 later) I've only had 2 subscribers from that blog post. Not a good ROI. I had them configure the pop-ups twice and still no results. I was hoping to get my money back since they told me there was a money back guarantee, but my last 2 emails have gone unanswered. Maybe this review will get them to contact me?

This app may be useful in the free version. But SUMO charged me $200/month due to the size of our business. All they did was set up a pop up for our mailing list, and a pop up to help with abandoned carts.

When asked to work with us on a monthly basis to improve conversions and sales, they gave me some tips of things that I could "implement myself".

For that amount of money, I would expect many more features and more support from the "VIP" support.

I'm switching to Bold, because it can do much more than Sumo for half the cost.

SO MANY BUGS. I wanted to like it, but it was INCREDIBLY frustrating to use—I lost tons of work and three days later, I'm still not sure if it's set up correctly. Support is unhelpful (although it's not their fault the app is so horrible). Avoid this app.

Somehow we got tricked into a 300 a month plan with a 30 days money back guarantee. Yet the Shopify plans show the top plan at 79 a month. They will use the sales comment how much is it worth to you! Bad sales tactic to charge everyone different prices? Not very transparent, if you ask us. The guy on webcam matt made up some super large numbers for sales we should get back. Did not happen and was not happening. We saw this very fast and asked to cancel and get refunded about 20 times or so. We have yet to be refunded our 300 bucks. We were told we would be getting a custom service yet it all seemed generic. Nothing was even branded to our website. The service in its self is very simple and sure not worth 300 or more a month. We feel they are taking advantage and, making false promises. We told the guy on the webcam we had bad experiences with other apps and was worried about trusting again and he acted like with there company no problems would happen because of the 30 days promised refund. Ok, then matt were is the refund? At this point, we are not sure we will be doing business with any apps anymore as they do not keep there word or promises, heck they do not even stand by the plans they have listed on Shopify, they just make them up as they go along. Why are apps going down such a bad road? Why do this to hard working businesses? Really guys, why? Just be honest with people, treat them right and don't make up lies. If they refund us anytime soon will update this.

Its a scam... nothing is free. They will first go through you all the hardwork and right at the end, you will have only one choice - a 14-day Trial and a ridiculous amount of money per month.
It's a deception, they are NOT FREE
Shopify should look into this and force them to immediately remove the FREE tag so they can stop wasting other people's time.
