Mailgun Validate
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.

Observational summary written by xpay from the signals captured on 2026-05-04. Not a review of the product — only of its current pricing posture for agent buyers.- Pricing is publicly visible on an indexable page — agents can read tiers without scraping past auth.
- Per-unit billing is published, so an agent can budget for a single task before committing.
- API documentation is reachable without a login — discovery and integration can happen in one session.
- Per-unit rate is concrete enough that an agent can model expected spend before issuing a request.
- A free tier exists, lowering the bar for an agent builder to prototype before committing budget.
- Some tiers are sales-led; the highest-capacity surfaces are not self-serve.
- PPU requires account creation and an issued API key; a fully unauthenticated agent purchase is not yet supported.
- No /.well-known/ai-pricing.json or equivalent machine-readable pricing manifest is published — agents must rely on HTML scraping.
How Mailgun Validate could lift its score
Mailgun Validate lands at Verified. Two missing points: (1) publish /.well-known/ai-pricing.json mapping the validation per-100 rate; (2) front a Stripe Payment Link for a one-shot validation credit pack so an unauthenticated agent can purchase without subscribing to a send tier first.
