Clicking Snooze hides the popup immediately and remembers, in your browser, not to show it again for 3 days — even if the underlying condition is still true. Snoozing is entirely local to the browser you're using; it doesn't tell Sprwt's servers anything.

Two of the eight popups — Verify your sender email and the Stripe missing-information popup — don't have a Snooze button at all. They simply re-check and can reappear once a day for as long as the underlying issue remains unresolved.
