Encourages upgrading to a paid or higher plan. Real examples from SaaS brands, captured from actual signups.
Upgrade prompts ask free or lower-tier users to move to a paid or higher plan. The best ones are triggered by a real moment of need, like hitting a limit or using a feature often.
"You have used 90% of your free sends" converts because the need is already real. Calendar-based upgrade pushes rarely do.
List the two or three paid features that matter for what the user is doing, not the whole pricing page.
Mention monthly billing, a guarantee or how easy it is to downgrade.
