Solved it myself! Anyway, adding another step where a function provides the line breaks and then using the automation to copy the function field instead of the multi-select field fixed it up right. Only took a couple weeks of looking at other folks’ posts and trial and error...

FYI: Airtable recognizes <br> as a line break when sending emails.

Weirdly, the Airtable Documentation just appears to be wrong in this case. It says rich text fields do not support URL hyperlinks, but they do? It’s working for me anyway.

The problem here was getting a line break and URL into a multiselect field that was being pulled into the email. 

1. I had to create a function for the multiselect to break it into a format with line breaks. 
2. I then had to create an automation to write that function field into a rich text field.
3. The rich text field can then be pasted into the email and that gets you line breaks and hyperlinks. 

Ultimately pretty easy to do, just took a lot of trial and error for me to finally see it work.

​@Sherman oh wow, you are completely right. I did not pay attention to the fact that the check emoji was not there for long text fields with rich text. It always worked for me too!
