The difference
Leads have shown interest (filled in a quote form, for example) and cost pounds each. Data costs pence per record and needs your team to qualify it — but you get far more people to talk to.
When data wins
- You have a call centre or BPO with agents who can qualify.
- You need volume every day.
- You want control over targeting and cost.
Interest data: the middle ground
Some DataMembership filters capture interest — people who said they want solar or new windows and doors — giving you warmer data at data prices.
Questions
Are your records leads?
No — they are opted-in data records for your team to qualify.
