Here is a number that should change how you think about repeat purchases.

45 days.

That is the window. After someone buys from you, you have approximately 45 days to get them to buy again before their likelihood drops off a cliff.

Most boutiques? They wait 60, 90, sometimes 120 days before sending a meaningful follow-up. By then, the customer has moved on.

The data is clear. First-time buyers with personalized post-purchase communication have 45% higher second-purchase rates. Not 5%. Not 10%. Forty-five percent.

So what should you do in those 45 days?

Day 1: The Thank You

Not a receipt. A genuine thank you. Set the tone. Make them feel good about their purchase.

Day 7: The Check-In

How is the product working out? Any questions? This builds trust and opens dialogue.

Day 14: The Education

Show them how to get the most from their purchase. Style tips, care instructions, unexpected uses.

Day 30: The Soft Offer

Not a discount. An invitation. Early access to something new. A complementary product suggestion.

Day 45: The Ask

If they have not bought again, now is the time for a gentle nudge. A small incentive. A reason to come back.

Miss this window and you are starting from zero. Again.

The best part? This entire sequence can be automated.
