# What is Database reactivation?

Database reactivation is a campaign that messages past customers who have not bought or booked in 6 to 18 months with a short, personal, non-promotional SMS or email, and lets AI handle the replies and bookings. The report calls it the highest direct-revenue automation for SMEs, typically lifting revenue 15–25% with zero ad spend, because most companies hold 1,000–10,000 forgotten contacts.

## What the message sounds like

'Hi Tamás, Péter from KlímaPro. I see we serviced your unit last May. We just opened the pre-season calendar; want me to pencil in the usual slot?' The AI segments contacts by history so every message references something real.

## FAQ

**Is this allowed under GDPR?**

For existing customers under legitimate interest, generally yes, with a clear opt-out. Any STOP reply blocks further messages automatically.
