Subject line
[NAME]'s free trial of Slack Pro ends in 7 days
What it is doing
A single-column trial reminder that leads with the deadline as the headline, then two dated lines on what happens next: upgrade and pay nothing until the trial ends, or do nothing and return to the free plan with no card needed. A locked-file illustration and a short list of what the team loses sit above one button.
Worth stealing
It answers the two questions a trial user has, what happens if I pay and what happens if I don't, before it asks for anything.
