We have taken all of our in-app emails out of SendGrid, and use Knowtify instead. But they use SendGrid, so Knowtify is just a layer between us and SendGrid.
Founder & CEO - Peerlyst, Inc.
We use our own product, Knowtify. We use it for all our customer email needs - from our product emails to our onboarding and retention emails as well as our general announcements and newsletters. We have all of our customer touch points here so we can track them all in one place.
