Sending reminders about limited offers can be useful, especially when it is done in a polite and clear way. Some people simply forget, even if they were interested at first, so a friendly reminder can help them make a decision. The reminder should not sound like pressure. It should explain what is ending soon, why it might be helpful, and give them time to think. Too many reminders can annoy people, especially when it feels like the same message repeated again and again. A short reminder with a helpful example usually works better. How often do you think reminders should be sent when an offer is about to end?
