> Email verification API with Pre-Send Decisions: every address gets a confidence score and reason codes instead of a bare valid/invalid label, so uncertain results — like a catch-all domain — are reported honestly instead of rounded up to "valid".

Work-email accounts receive 1,000 free verification credits every month. Public-email accounts receive 100 free credits once. No card required. Subscription and pay-as-you-go credits never expire. Catch-all evidence follows the normal pass for eligible addresses and is included in standard verification on every plan, with no additional credit charge.

## Docs

- [Bounceless — Email verification with Pre-Send Decisions](https://www.bounceless.io/): Verify, validate and clean email lists at scale with one API. Power AI sales agents with deliverable email data.
- [FAQ](https://www.bounceless.io/company/faq): Answers on Pre-Send Decision, catch-all handling, reason codes, free credits, and how to reach Bounceless support.

## Features

- [Bulk Email Verification API](https://www.bounceless.io/features/bulk-verification): Verify entire lists asynchronously: upload a CSV or call the bulk endpoint, poll or get a webhook when the job finishes, and export confidence and reason codes per row.
- [Catch-All Detection](https://www.bounceless.io/features/catch-all-detection): Catch-all domains accept every address at SMTP time, so verification cannot confirm a specific mailbox. Bounceless surfaces that as low confidence, not a false valid.
- [Email Verification API & Dashboard](https://www.bounceless.io/features/email-verification): Verify email addresses with confidence scores, reason codes, and a Pre-Send Decision, not a bare valid/invalid label. API and dashboard, same contract.
- [Email List Cleaning & Email Scrubbing](https://www.bounceless.io/features/list-hygiene): Clean your email list before a campaign. Upload a CSV, review invalid and uncertain addresses, and export the contacts you choose to keep with Bounceless.

## Company
