SaaS Upgrade Prompt Email Examples
Sent when a user on a free or lower tier hits a limit, or looks like they are about to. The best of these are triggered by real usage and name the exact constraint the person just ran into, which makes them read as help rather than sales. Compare how products handle the hard wall versus the soft nudge, and how many mention price at all in the first email.
