Customer engagement via onsite messaging was a challenge until i found JustUno. The tight Shopify and Klaviyo integration are huge bonuses when compared to lightweight "pop up" apps. One of the big concerns we have around other "pop up apps" is site speed slowing and where our data is going. No issues with site speed when using JustUno and the JustUno website and documentation is clear and transparent. With Just Uno you can also have targeted customer messaging in your checkout - which is a big plus for us. The JustUno rule engine is second to none, meaning, configuration of customer journey messaging and promotional campaign messaging is no longer a headache for us to manage. Setting up display triggers and rules is a drag and drop process - very easy and intuitive. The Team at JustUno and their support (Stephanie & Zach) are fantastic (thank you to both of you for helping us). App installation and JustUno campaign setup is easy to do as well. Creating and configuring mobile and desktop messaging is also easy to do given the extensive template library within Just Uno. If your looking for a single site messaging solution that works extremely well with your email marketing provider then look no further.

Our ability to keep site speed at top-notch is one of the best value adds from our platform - your brand has successfully built on-brand promotions with rich media and seen no effect on load-time. SEO win! 🏆 We will pass along your kudos to Stephanie and Zach and are glad your Justuno Plus strategists are helping you squeeze the full value out of our CRO suite.

Great for what I needed it for. Advertising banner sales, events etc. Easy to use. Some times the mobile view is a little tricky

Thanks for your feedback! We're glad you're leveraging different display types for sales and events. If you're finding the mobile view a bit tricky, we'd suggest you use our library of pre-built templates. There you can find a mobile-friendly template to start from, then can easily customize the branding and sync up the integration with your provider, if needed. These also have our best-practice mobile targeting rules already set for you, so you don't have to worry about customizing anything there.

Should you ever need any additional support in getting your promotions designed "just right" feel free to reach out and someone on our team will take care of you. Thanks for being a Justuno customer!

This app has helped us convert and retarget new and existing customers. What we love most is the amount of support and resources we receive, especially being a very small company with limited bandwidth. Our strategist, Miranda Galindo has been such a huge help and asset to us. From coming up with different marketing strategies and ideas to being readily available to any questions we have - she has been such a pleasure to work with. She is also always willing to jump on a call to help walk through any questions or promo build-outs. Very happy with Justuno!

We've been on JustUno for quite awhile, but with our recent NYT feature we had to get serious, and quick. Took a leap and jumped into Justuno professional and it's been phenomenal. We may have just gotten lucky because Miranda G. understood our need to execute quickly and has done exactly that for us and more! The learning and high level thinking we've been able to do as a team has been a gamechanger for us. Highly recommend!
