Sumo does a great job and it fits my needs really well. The only thing I would improve is the visibility bullet point in a campaign, the settings are a bit confusing and a description about the Smart Mode would be helpful.

The Rave Spot

The free version is very basic but my issue turned out to be something separate and their response was very helpful.

Reform Sport

super helpful support guys solved my problem without me complaining over and over. Took the time and initiative to solve it when I had given up.

No1 Rosemary Water

Great app for our promotions and super helpful support team have been on hand to help us get set up!

Lyger Technology

Great resource. I needed something to organize my subscribers. But I couldn't find where or how I could send out new emails.


It has been great working with Sumo. The team has been very efficient and helpful and we see great results!


Our email growth rate has been steady week after week. It's definitely helped increase our subscriber count. I'm not so confident our overall conversion rates increased as high as they promised, but the list growth is important enough for us to justify the continual use.

pretty user friendly,reasonable ability to customise - some terms could be a little bit more user friendly for novices. eg GET vs POST

Shire Post Mint

The staff was very helpful in putting the ad together. Once I was onboarded, the support was much less involved. The two pop ups that they put together are working very well, but I'm not sure that the extremely high subscription price is worth it in the long run. I felt railroaded into the contract price and I wish they were more up front about the cost. The service people were sweet and helpful.

EDIT: After writing this review, the Sumo team reached out and continue to routinely check up and see if there are any more strategies that we can try together. I have seen an increase in conversion rates and subscribes. The price is rather high for a very small business, but for stores with high volume, this is a must-have. I still wish they were more up front about the total cost.

The Dadness Shop

Sumo provides an excellent service!! Only leaving 4 stars instead of 5 because I remember a time not so long ago when there were more customization options with the free plan -- especially w/ the popups -- (sigh). But yes, I'd recommend it (and do) to anyone!!
