"Quality" is argued about endlessly. Contact rate is not. A lead you cannot reach has no quality at all, and whether the mobile was verified before delivery is the single biggest driver of whether you reach it.
SMS verification means the prospect received a code on the mobile they entered and typed it back before the enquiry was released. It proves the number is real, live and in their hand. It does not prove intent or creditworthiness; qualification questions do that.
Email verification proves an inbox exists. "Phone verified" can mean anything from an SMS code to a pattern check on the digits; ask which. Unverified means the form was submitted and nothing was checked.
A share of dead numbers, typos and fakes, paid for at full price, discovered one voicemail at a time.
Drop-off: some prospects abandon the form at the code step. Providers who verify accept fewer leads to deliver reachable ones.
Contact rate: the share of leads where you reach a person. Ask every provider for theirs and how it is measured. Ours is published: 72.5%.
Slow follow-up. A verified enquiry called the next morning still converts worse than one called within the hour.
Every enquiry across business loans, asset finance, commercial finance and ATO tax debt is SMS-verified before delivery, then reviewed against the stated criteria for that flow. Enquiries that fail either step never reach a broker. Each one is sold once. Read how that compares with the shared model in exclusive vs shared leads.
