Extremely customizable — from tenant to template! The ability to run mock notifications is great! Yes!

I like that SuprSend has a nice UI. The integration is really nice and technical support on Slack has been really useful. It's great to have help available in the Slack channel to sort things out. They fix issues quickly when things aren't working properly. The translation integration is really nice because we can automatically send and fully transfer things to our users without much overhead. It's easy to work with, and I also think the SDK made the setup pretty easy, especially for phone user registration. The documentation is good as well, and it works well with other tools like Phrase for notification setup.

Easy to use platform for managing all of our communications. Low on cost. Responsive team. Easy intuitive integrations. Quick development time for requested features. They have been quite helpful on many fronts including helps in debuggin and responding to external incidents.
