I have three columns:

  1. Email
  2. Sent (Yes/No)
  3. Date (Sent)

I would like to add a fourth col to display the number of days since the email was sent (i.e. Current Date - Date Sent, displayed as Days). How can I write a formula for that?

Use DATETIME_DIFF():

Also, I think you could remove the Sent field, cause you already have that information in Date field: if it is filled, it is send.

I would just do:

TONOW({Date Sent})
