In their own words
Bounceless
Bounceless verifies and cleans email lists, returning confidence levels, reason codes, and a Pre-Send Decision to send, review, or suppress each address. Its checks cover syntax, domain and MX posture, and mailbox signals when the receiving server permits them. Catch-all addresses receive reduced confidence because the service cannot confirm a particular mailbox; Gmail and similar major webmail providers are marked uncertain rather than safe to send. Users can upload a CSV through the web workspace or use the API, then export results. The REST API and event webhooks use the same result format, as do its MCP server and agent skills. Bounceless does not offer native app integrations; it describes CSV export, bulk verification, and re-import workflows for email platforms. A base check costs 1 credit, fresh deep catch-all resolution costs 5, and cached resolution costs 3; unknown results are not billed. Platforms are web and API. A free plan includes 1,000 credits monthly; paid plans start at $19/mo, and one-time credit packs are also listed.
Email Verifier API
Email Verifier API checks email addresses in real time to help reduce bounces and protect sender reputation. Its verification engine runs 16 checks, including syntax, SMTP, MX and DNS validation, spam trap detection, disposable and role account checks, and catch-all detection. Users can also upload CSV spreadsheets to clean lists.
The REST API accepts GET or POST requests and returns JSON by default, with XML available using an xml parameter. Each check uses one credit, but only definitive Passed and Failed results are billed; unknown catch-all results are not charged. The browser tool allows five daily checks without an account, and a new account receives 100 free credits without a credit card. Purchased credits do not expire, and the pricing page says purchases do not renew automatically. One-time packs include 1,000 credits for $9.95, paid once and 1,000,000 credits for $2,499.95, paid once. The service lists guides for C#, Go, Java, Node.js, PHP, Python, Ruby and Swift, and says submitted email addresses are purged after checking.
