Monthly verifier seats feel simple until a quiet week still bills you. Here is how to think about pay-as-you-go email verification credits — and a free calculator to model your lists.
Seats vs packs
- Monthly seat / subscription: you pay for calendar time. Unused capacity often resets.
- PAYG credit pack: you prepay for verifications. With Verifly, credits never expire and there is no monthly seat.
If your GTM or recruiting volume is bursty (Clay weeks, campaign launches, ATS exports), packs usually win on effective cost.
What to model
- Emails per week (or per campaign).
- How many are already known-good vs need a live check.
- Whether you fail closed on disposable / role (still a verify call).
- Parallel tools: Clay HTTP column, n8n, Zapier, bulk CSV.
Open the calculator: Verifly credit calculator
Rough pack anchors (confirm on pricing)
- Starter: 5k credits / $10
- Higher tiers down to about $0.60 per 1k at the 1M pack
Always check current pricing before buying.
API shape (so automation is easy)
# real-time
curl -X GET "https://verifly.email/api/v1/verify?email=lead@example.com" \
-H "Authorization: Bearer vf_your_api_key"
Batch ≤100 via POST /api/v1/verify/batch. Async bulk for large cleans. AI agents can use the same credits through REST or /mcp.
