Email to SHA256 for Ad Audiences

What this skill does

Takes a business email address and returns SHA256-hashed personal email addresses for that person using business_email_to_sha256. The hashes are privacy-safe identifiers you can upload directly to ad platforms that support customer match or custom audience workflows - Meta, Google, LinkedIn, TikTok, and most DSPs.

Use this when you have business emails from your CRM or outbound lists and want to reach the same people in paid channels.

Inputs

• Business email - single address or a list (processed one call per email)

When it activates

• "convert this business email to SHA256"
• "get hashed emails for [email]"
• "build a custom audience from these business emails"
• "hash these emails for Meta / Google"

Output

Emails processed:  X
Hashes returned:   X  (XX%)
Credits used:      ~XXX

Tips

• Not-found results are free - only matched emails are charged
• Output is formatted for direct upload: one hash per row, no plaintext exposure
• Starting from LinkedIn URLs instead? Use LinkedIn to SHA256
• Need device IDs for mobile targeting? Email to MAID needs a plaintext email, not a hash - resolve a personal email first, then run it
