<b>The pre-send scrub stack that saves your reject rate</b>

Forex buyers reject on duplicates, recycled numbers, and dead emails. Scrubbing before delivery beats arguing after.

<b>What this is:</b> A layered check between lead capture and delivery: dedup, email deliverability, phone line-type, and IP/geo sanity.

<b>Best for:</b> Anyone delivering raw leads to a desk that pays on validity, not just submission.

<b>The layers, in order:</b>
— Internal dedup first (hash email+phone) — free, kills the most common reject
— Email check (ZeroBounce or Kickbox) to drop hard-bounces before they count
— Phone line-type to flag VOIP the call center will bin
— IP-to-GEO match so a 'UK' lead from an Indian datacenter IP gets caught

<b>Cons to watch:</b>
— Each layer adds latency; real-time ping-post buyers time out around 1–2s
— Over-scrubbing kills marginal-but-real leads and your fill rate
— Email validators disagree; one vendor's 'risky' is another's 'valid'

<b>Who should skip this:</b> If your buyer scrubs on intake and tells you why each lead failed, mirror their rules exactly instead of stacking your own — duplicate logic just shrinks volume.

Verdict: Scrub to their rules, not yours.
