When sending an email with the Gmail pack, you may sometimes notice that the newlines get removed in the final message. This is annoying (it happened in my Email Campaign Template). Turns out there is a really simple fix.
See this doc:
Short answer
Create a column with this formula:
MyText.Format('{1}{2}', _bold(' '))
This will convert it to rich text, then email the contents of that column and the newlines will show up like normal.
