It took their support team 12 days and several exchanges including a call with a sales rep to give my question a final answer.
Their free plan is extremely limited, it imports random shipments and doesn't let you test anything properly. Yet they expect you to pay 99$ to use an app you weren't able to test.
We're going to use Aftership, who have fast support and a lot of features.

Wonderment is now our go-to Shopify app, an absolute essential for any store. Thousands of shipments later, and we've yet to receive a single customer support ticket for order updates, thanks to Wonderment's proactive triggers.

Special kudos to Sivan for going above and beyond during our integration. Her expertise ensured a seamless and tailored success. Wonderment's features, combined with Sivan's exceptional support, make it a five-star, must-have solution for any Shopify store!

We've had an incredible experience with Wonderment. not only has it drastically improved our customer experience with transactional and post-purchase messaging, but it drives revenue and helps us "brand" previously unbranded experiences. Plus, it's awesome to have all of the flows in Klaviyo (Wonderment team 100% built them out for us and all we had to do was give feedback and a green light).

Speaking on behalf of Rejuvia and 1-800-D2C, can't reccommend the wonderment platform and team enough!
