FlowMail

Works exactly as expected and haven't had to contact support so I guess thats a great thing!

Really useful app that allows you to send emails that are necessary for selling your products, without running into Shopify's restrictions on transactional emails. Dev team are very responsive and added a feature request in under 24 hours. Highly Recommend!

App works well, and the team is extremely responsive. I had an issue that was resolved within 5 minutes. When I had a separate question, they explained via email and also offered to have a call to walk me through the issue.

These guys are the best.
I thought the app was very useful when I was just tinkering with it myself.
Oleksandr from Flowmail helped me out and blew me away with what this app is capable of.
Great app and absolutely fantastic customer service.

The app works well and the team is very responsive – they resolved an issue I had almost immediately and are working on adding a new feature that I requested.
