1: dynamic tags you can specify in json like the pre placed holder provided. This is used for the builder interactions.
Since you’ll be using your own sending service you’ll need to :findandreplace and specify your tags and the value to be replaced by.
2: they get stored based on your unlayer plan check their pricing (or free plan) for info on storage length etc.
You can save the returned value by doing :savedtoS3
3: you can clear the groups contents or better yet IMO is when initializing the builder do it based off a blank template ID created in your unlayer dash so every load is fresh.
If you need more in-depth help send me a message and we can schedule an consultation on it.
Things we use the builder for:
save and edit email templates
send custom emails
allow users to create proposals with signature boxes
load custom elements
allow users to build simple 1 page websites/landing pages
allow users to create email blasts
Much more! At a core level it just exports HTML/CSS/JS based on the builder. JSON to reload into the builder.
