Improved
New merge tag syntax with curly braces
21 days ago
Merge tags now use curly braces: write {firstname}, {company}, or any field key wrapped in {…} in your subject line, pre-header, or email body. The editor's merge tag picker inserts the new syntax automatically.
The old %%fieldname%% syntax is deprecated but still supported — existing campaigns and templates keep working unchanged. For anything new, use the curly brace form.
