Dear {First_Name},
Thank you for dining with us at {Restaurant_Name}!
I hope you enjoyed the food, the atmosphere, and the service. We’d love you to come back to visit us soon, and that’s why I’d like to make you a special offer:
Choose from our mouth-watering and sinful {list dessert options here}.
Why would I give away free desserts?
Well, the answer is quite simple: I know from experience that if I can get you to come back here a second time, you’ll keep dining with us over and over again.
So giving away a free dessert is a small price to pay to earn your loyalty!
I hope to see you soon.
Bon Appetité,
{Your name}
