Payment evidence: current spend or explicit intent

ProblemAfter B2B teams scale up cold email outreach, surging send volume causes deliverability to drop significantly. They lack unified control over domain reputation, sender configuration, and recipient list health.

People affectedGrowth, SDR teams, and independent sellers shifting from small-batch to large-scale B2B cold email.

What this evidence does not show yet

To reach Payment-backed we still need:

1 more independent post(s) — we have 4
a first-hand payment statement — either someone naming what they already pay, or 1 more statement(s) with a specific amount they would pay (we have 1)
renewed mentions — the recent trend is below the promotion bar

Scoring summary

Evidence confidence = strength × evidence volume × source diversity × payment × competition × trend × 10. Counts use independent content items; only first-hand pain, current spend, explicit willingness to pay and concrete feature requests affect the score. Repeated posts by one author are discounted. Scoring and status changes follow deterministic rules.

“Payment-backed” means first-hand payment evidence exists in the record. It does not mean the business is worth building. “Fading” is a recency tag shown alongside any evidence level, not a lower level. Read the full methodology.
