For everyone looking to take part in the public beta, you can enroll your portal(s) through the Product Updates section by searching for “Dnd Areas.”
The newest update allows the use of custom modules in the coded template as well. Which is very helpful to create more complete templates. Previously in the beta, you could only use default HubSpot modules. Which wasn’t enough for our clients that have more complex email designs.
We have been using this beta for two of our clients since it first became available. So far this beta has worked very well for enabling complex designs that require hybrid coding and made it possible to support web fonts for those ESP clients that will show them.
