How the Workflow Functions:

1. Airtable Node: Automatically extracts all email records from your designated table that require validation

2. Mailcheck Node: Processes each email address through sophisticated validation algorithms to determine validity, checking syntax, domain existence, and mail server configuration

3. Set Node: Formats the validation results into a standardized structure for consistent database updates

4. Airtable Update Node: Automatically writes validation results back to your original table, updating the 'Valid' field for each record

The entire process runs autonomously on your schedule - daily, weekly, or before major campaigns, ensuring your email database remains consistently clean and reliable.
