01 · The context

Challenge

The insurer's 180k-record prospect database was three years old. Only 52% of records were accurate when spot-checked; direct dials were at 38% accuracy. Outbound was burning budget on dead numbers while DSGVO risk was compounding with every outdated call.

02 · The approach

Solution

Teleroids ran a full validation pass on the database (SMTP ping, number status, LinkedIn presence, Handelsregister check), retiring 31% of records and re-enriching another 24%. Two reps ran the cleaned list with new scripts pre-approved by the client's DSGVO officer. A continuous 30-day re-validation loop was built into the workflow.

03 · The outcome

Results

Dial-to-connect doubled. Rep productivity per hour rose 72% because they were no longer burning time on dead numbers. Cost per qualified lead fell 63%, lead-to-quote rate rose 52%, and zero DSGVO complaints were logged across 24,000 dials.
