Stick to standard formatting and safe HTML: Bold, italics, headings, lists, tables, images, and links.
Avoid pasting content directly from other email builders or word processors:
These often inject custom tags, tracking markup, or editor specific attributes that are not on the whitelist, for example Grammarly markup.
Only use
http,https, ormailtolinks.Do not add scripts, embedded objects or iframes, or interactive
onclickstyle behaviour.
