Verifalia
verifalia.com · Email Verification
81
/ 100
Agent-Ready Verified
Verifalia exposes both a PAYG credit-pack ladder ($7.90/1k down to $4,890/10M) and a five-tier subscription matrix from Free through Ultimate $499/mo, with multi-currency pricing and quality-level pricing rules (Standard 1cr, High 2cr, Extreme 4cr) clearly stated. Open-source SDKs and developer docs are public. xpay could not verify a machine-readable pricing manifest or anonymous one-shot purchase.
#2
MailerCheck
mailercheck.com · Email Verification
81
/ 100
Agent-Ready Verified
MailerCheck runs a single-tier PAYG model at $0.01/credit (minimum 1,000 credits = $10) with explicit credit costs for verification (1cr), Email Insights (200cr) and Inbox Placement (200cr). Credits never expire. No sales-led tier exists at all. Docs and API reference are public. xpay could not verify a machine-readable pricing manifest or an anonymous one-shot Payment Link.
#3
ZeroBounce
zerobounce.net · Email Verification
78
/ 100
Approaching Agent-Ready
ZeroBounce exposes a slider-based PAYG pricing widget ($0.0138/credit at the 5,000-credit anchor) alongside a ZeroBounce ONE subscription discount and a freemium with 100 free monthly validations. Credits never expire and unknown results are free. Developer docs are open. xpay could not verify a machine-readable pricing manifest or an anonymous one-shot purchase.
#4
EmailListVerify
emaillistverify.com · Email Verification
78
/ 100
Approaching Agent-Ready
EmailListVerify publishes a PAYG ladder from $6.99/1k credits down to bulk monthly subscriptions at $0.00032/credit, with explicit per-credit cost on every row and an open API endpoint. Every tier shown is self-serve. Credits do not expire on PAYG. xpay could not verify a machine-readable pricing manifest or one-shot anonymous Payment Link.
#5
Kickbox
kickbox.com · Email Verification
77
/ 100
Approaching Agent-Ready
Kickbox publishes a fully volume-tiered PAYG ladder from 100 free verifications up to 1,000,000 for $2,999, with the $5 anchor at 500 verifications well under the low-minimum threshold. Unknown verification results are refunded. Self-serve checkout is universal across the volume table; only the >1M segment routes to sales. Public docs are open. xpay could not verify a pricing manifest or anonymous one-shot purchase Payment Link.
#6
Bouncer
usebouncer.com · Email Verification
76
/ 100
Approaching Agent-Ready
Bouncer publishes a transparent PAYG ladder (1k credits for $8 down to $0.002/credit at 1M), an optional monthly subscription, plus separately metered Deliverability Kit and Bouncer Shield products. Credits never expire and unknown results are free. Self-serve covers the entire pricing table. Docs are public. xpay could not verify a machine-readable pricing manifest or a one-shot anonymous Payment Link.
#7
Emailable
emailable.com · Email Verification
76
/ 100
Approaching Agent-Ready
Emailable publishes a PAYG+subscription slider from 5k credits ($38) up to 1M with credit-cost-per-feature mapping for Bulk, Verifier, API, Widget, Inbox Reports, and Blacklist Monitors. Credits never expire and 250 are granted on signup. The minimum 5k credit purchase puts the entry point above $20 but unit cost remains explicit. Self-serve across all volume tiers; Enterprise routes to sales above 1M.
#8
Mailgun Validate
mailgun.com · Email Verification
74
/ 100
Approaching Agent-Ready
Mailgun's pricing page exposes four send tiers (Free, Basic $15, Foundation $35, Scale $90) with explicit per-100 validation overage rates and per-1k email overage rates on each plan. Validations are sold either bundled (5k included on Scale) or as add-on against any subscription. xpay observed that the validation product is metered alongside the send subscription rather than as a standalone PAYG SKU, which is observed as a softer fit on the usage-based axis. Docs are open.
#9
NeverBounce
neverbounce.com · Email Verification
73
/ 100
Approaching Agent-Ready
NeverBounce headlines a true PAYG model at $0.008/credit (1,000 credits for $8) plus a $49/mo Growth subscription and a sales-led Enterprise plan. Per-credit semantics are explicit, credits expire 12 months post-purchase, and developer docs are public. xpay could not verify a /.well-known manifest or a one-shot anonymous purchase Payment Link.
#10

61
/ 100
Partially Agent-Ready
Abstract's email validation product publishes Free (100/mo), Starter, Standard, Professional, Enterprise tiers with monthly/annual toggles and a request-volume slider that exposes the implied per-call rate. Public docs and live demo widget are open. xpay observed quotas inside the subscription rather than a true PAYG meter, which is observed as a softer match on the usage-based axis.
