Love Monster Upsell. They always reply super quick and find answers to any questions if they don't know.

I had an issue with something showing on my website and the customer service was super quick, efficient and kind while helping fix this.

The support is amazingly fast and efficient ! I had an issue and was able to fix it within minutes ! Really recommended app and support.

Awesome features and great support via immediate online chat.

The app itself is solid and works well once it’s set up. Functionally, it does what it’s meant to do and can be a strong part of a checkout flow. We initially ran into trouble when preparing updates heading into 2026. An issue locked us out of making changes, and early support responses suggested the problem was on our side, even after testing across multiple devices. That was frustrating at the time. That said, after we posted our original review, the owner personally reached out and the experience completely turned around. They acknowledged the issue, made system upgrades, and walked us through the migration step by step. The level of personal attention, accountability, and follow-through was genuinely appreciated. As a business owner myself, I know things happen. What matters is how they’re handled. In this case, the issue was owned, resolved properly, and communicated clearly. Because of that, we’re updating this to a 5-star review. The app is solid, and when support shows up the way it ultimately did, it makes a real difference. Hopefully this becomes the standard experience moving forward.

Epic app with a brilliant dashboard to understand ROI. Easy interface to use and the customer service is next-level awesome.

absolutely loving this customer service team always so helpful and get the job done right away HIGHLY RECOMMEND!

Great app! Easy to set up and excellent support. Provides a very professional, branded addition to our customer's journey that made us $ from day one! Highly recommended.

Love this app and the founder Ty so much! If I could give 10 stars I would! I had a small issue with my dynamic checkout and Ty jumped in and fixed it right away. I love the ability to offer free gifts and other upsells at checkout. Definitely gets conversions and has increased my AOV massively!! Would highly recommend!

Excellent service, both times I've had questions or issues they were quick to solve it!

Très bonne application avec un support très réactif et compétant !

The app is absolutely fantastic. It's really simple to use and does everything you need it to do. We use the app for all sorts of upsell campaigns and it never fails. Their customer support is also extremely proactive and helpful. Highly recommend this app to anyone looking for a great upsell app.
