MailSafeProInstall

Summary

Validate up to 100 email addresses synchronously, checking each for validity, deliverability, and risk, optionally performing SMTP verification and including batch statistics.

Inputs

• Emails (required) — Email addresses separated by comma, semicolon, or newline (maximum of 100). Inputs are parsed, normalized to lowercase, and validated against a standard email regex before being processed.
• Options — Configuration options including: whether to perform SMTP verification ('Check SMTP', default false); whether to return each validation result as a separate output item ('Return Individual Results', default true); whether to include batch statistics in the output ('Include Statistics', default true); and whether to continue processing if some emails are invalid ('Continue on Invalid', default true).

Output shape

a list of validation result objects, each representing an individual email's validation data, or a single object containing aggregated results and statistics if individual results are not split

If 'Return Individual Results' is true or unspecified, the node outputs each email validation result as a separate item, each including risk level, quality tier, deliverability status, recommendations, and timestamp. Batch statistics may be included per item when 'Include Statistics' is enabled. If 'Return Individual Results' is false, the node outputs a single JSON object containing the batch's total submitted addresses, count of unique emails processed, duplicates removed, an array of all validation results, and aggregated statistics. Validation supports up to 100 emails; exceeding this throws an error advising the use of asynchronous batch jobs for larger lists.
