Start with customers who already know the business.

Retention is usually an operating issue first

Customers rarely experience a business as separate departments. A missed hand-off, unclear update or unresolved issue can outweigh a strong sales conversation. Map the points where the customer waits, repeats information or has to chase, then assign ownership for each next action.

Reactivation needs a real reason

Use what you already know about the previous work to identify a sensible follow-up: a renewal window, a changed requirement, a complementary service or a useful review. A generic 'we miss you' message gives the customer little reason to reply.

• Segment customers by what they bought and when.
• Check whether the previous outcome and any open issue are recorded.
• Offer one relevant next step and make declining easy.
• Record the response so the same customer is not repeatedly contacted without context.
