Bulk Email Validation

Utilities
POST /api/v1/email/validate/bulk Bearer

Bulk Email Validation API — the same deliverability check as Email Validation, for up to 100 addresses in a single billable call. Every entry in results has exactly the shape a single-address lookup returns, so one parser handles both endpoints. Duplicate addresses are collapsed before the lookup, and total_requested versus total_returned lets you detect a short response. Built for cleaning imported lists, validating CSV uploads and periodic re-verification of a mailing database.

What Bulk Email Validation Is Used For

List cleaning before a campaign

Validate up to 100 addresses in a single billable call before a send.

Imported data hygiene

Clean a purchased or migrated list before it enters your CRM.

One parser for both endpoints

Read entries in exactly the shape a single-address lookup returns.

Short response detection

Compare total_requested against total_returned to confirm nothing was silently dropped.

1

What it doesSaves your API key in this browser only using localStorage. Next time you open a docs page, the Try It panel is pre-filled automatically.

2

Auto-updatesIf you type a different key into any Try It field, the saved key is replaced instantly — only the most recent key is ever stored.

3

Uncheck to forgetUnchecking “Remember API Key” immediately deletes the stored key and clears the field. While unchecked, nothing is saved even if you type a new key.

4

Re-check to save againChecking the box again saves whatever key is currently in the Try It field.

⚠ Security note: Your key is stored only in your browser and is never sent to any server except as part of the actual API call you send. Do not use this feature on shared or public computers.
