A customer database is a digital or paper file that contains... Customer information Who interacted with your project, whether:

City or location

Select offers by region

The type of products he is interested in

Personalize content, products and offers

Purchase history

Knowing his habits and anticipating his next need

Date of last interaction

Determine when to reconnect

Second: Why is the database considered a powerful marketing tool?

1. Repeat sales at a lower cost

Instead of spending money to attract a new customer, you can simply Reconnect with a former client At almost no cost.

2. Build an ongoing relationship

When you address a customer by name and understand their needs, they feel that you care about them, which increases their loyalty and trust in you.

3. Provide personalized offers

• Offer a small gift for signing up, such as a 10% discount.

✅ advice: Make data collection quick and easy, and don't make the customer feel like you're intruding on them.
