MailBoxLayer presents a REST JSON email validation and verification API with syntax, typo, SMTP, and disposable filtering on mailboxlayer.com — a developer-facing check endpoint rather than a revenue-ops export policy tool.
Feature-by-feature, sourced
Every Mailboxlayer row below links to the public source it came from, or says "Not publicly disclosed" instead of guessing. One point per round: a tie means both products cover it, rounds without public information score nothing, and any price rounds in the Pricing band below count toward the same score.

What we won’t guess
Pricing, honestly
Beyond the table
Mailboxlayer and Bounceless both validate email, but Mailboxlayer sells an embeddable API while Bounceless sells verification policy on owned list export.

What about the maiboxlayer slug?
maiboxlayer is a legacy typo slug. Canonical spelling is mailboxlayer — see /compare/maiboxlayer for legacy routing context. Re-check the cited first-party URL before treating any row as current — we bind only claims from checked pages, not inferred feature depth.
Does Mailboxlayer ship Pre-Send Decision?
Checked pages describe validation API output — not a unified send, review, or suppress export column like Bounceless. Re-check the cited first-party URL before treating any row as current — we bind only claims from checked pages, not inferred feature depth.
Why are exact prices undisclosed in prose?
Pricing tiers are stale-sensitive. Bind numeric rows only after same-day review. Re-check the cited first-party URL before treating any row as current — we bind only claims from checked pages, not inferred feature depth.
When might Mailboxlayer win?
When a developer-oriented validation API at point of entry is sufficient without bulk send-policy export. Re-check the cited first-party URL before treating any row as current — we bind only claims from checked pages, not inferred feature depth.
