# Campaigns: emailing past customers

> Email a promotion or news to a chosen group of past customers.

**Campaigns** sends one email to a group of your customers, such as a low-season offer or news.

Make a segment first. A segment is a saved group of customers. Press **New segment**, name it, and choose who is in it: **Tags — any of these**, **Dives, at least**, **Spent, at least**, **Not heard from in (days)** or **Last dive before**. Press **Count** to see how many you may write to, then **Save segment**.

Write: Open the segment and write a **Subject** and **Message**, with a blank line between paragraphs, and send.

An email only goes to customers who agreed to marketing or who have a real past booking with you, and never to anyone who unsubscribed. Bookings brought in by an import don't count as past bookings. Every campaign email has an unsubscribe link.
