Beefree's email builder is white labeled by many ESPs, an example everyone from AppSumo will be familiar with is Acumbamail.
Acumbamail's email builder is just Beefree.
Same with Braze, Iterable, Customer.io, Blueshift, Bloomreach, Ongage... etc etc.
We will now have every feature you want in an email builder and every edge case for responsive design should be covered across all devices and apps.
This is one of our most important updates we've made so far and and I think everyone will be extremely happy to see this one.
