Unknown means the receiving mail server would not give a definitive answer on this attempt, usually greylisting or a temporary block. We report that honestly instead of guessing, never charge for it, and Re-run unknowns stays free until they resolve.
Webhook Signing Secret
Use this secret to verify webhook signatures. EVA signs each
payload with HMAC-SHA256 and sends the signature in the X-EVA-Signature header.

Buy Credit Packs
One flat rate: $1.20 per 1,000 at every size. Credits never expire and are used when your monthly quota is exhausted.
Pay with USDT on Polygon or BNB Chain for near-zero network fees (under $0.30). TRC-20 (TRON) also works, but transfers from a personal wallet cost $3–6 in network fees — if you use TRON, withdrawing directly from an exchange (≈$1 fee) is much cheaper.
