How to describe Spaw, the facts that stay true, and the logo files. For directories, listings, articles, and anyone writing about the email verification API.

Everything on this page may be quoted as is. If a fact here disagrees with an older mention elsewhere, this page is the current one.

## One-line description

Spaw is an email verification API: one key, one credit balance, and a verdict that names its reasons and its data sources.

## Short description

Spaw verifies email addresses without sending mail. Every lookup checks RFC syntax, live DNS and MX records, SPF and DMARC, open disposable and role lists, provider username rules, and runs an SMTP mailbox handshake that never transmits a message. Verdicts are deliverable, risky, or undeliverable, each with a machine-readable reason and a 0 to 100 risk score built from published weights. Every account gets 10 free lookups a month with no card; you pay 1 credit per answered lookup and nothing for undeliverable results.

## Long description

Spaw (spaw.co) is an email verification API launched in 2026. It answers one question per address: will mail to it arrive, and how much should you trust that answer? A lookup runs the whole pipeline every time: syntax parsing after stripping display names and stray characters, live MX resolution with null-MX, implicit-MX and unresolvable-MX handling, SPF and DMARC records, the open disposable-provider and role-address lists, provider-specific username rules, a curated typo-squat map, domain registration age from RDAP, and an SMTP mailbox handshake that ends before any message is transmitted. The response carries 27 named fields, the datasets and versions each answer came from, and a risk score that is a published sum of weights rather than a black box.

Spaw bills for answers only. A deliverable or risky verdict costs 1 credit; undeliverable verdicts, invalid input, rejected requests, and repeats within 7 days cost nothing. Every account receives 10 free credits a month, and credit packs are one-time purchases that never expire. The same engine is available through a REST API with an OpenAPI 3.1 document, a dashboard with bulk uploads, a browser form widget with domain-locked publishable keys, a bounce feedback loop, scheduled list monitors, and an MCP server for AI agents. Phone validation and IP intelligence are in development.

## Naming

Write "Spaw", capital S, no article: "Spaw verifies…", not "the Spaw". The domain is spaw.co. Do not describe Spaw as a proxy service, a mail sender, or a data broker; it does none of those things and never sends mail on anyone's behalf.

## Logo files
