If you run Meta (Facebook/Instagram) ads, you can export your BCKSTG subscriber list as a hashed Custom Audience file, ready to upload directly into Meta Ads Manager to target your fans or find lookalike audiences.
Connect Meta Account (Soon) sends the hashed emails straight to an audience in your own ad account. If your account has it, you'll see it in the same place.
How it works:
- Go to Dashboard → Guest List → Tools
- Click Export for Meta Ads
- BCKSTG generates a CSV with your subscribers' email addresses hashed using SHA-256
- Download the file and upload it to Meta Ads Manager under Audiences → Custom Audience → Customer List
What is hashing?
Before the file is created, every email address is converted into a scrambled string using "an industry-standard process called SHA-256 hashing." The actual email addresses are never in the export, only the hashed versions. Meta's system can match these hashes to its own user database without either party seeing the raw emails.
Plan required:
Pro or Lifetime.
Notes:
- The export reflects your list at the moment you click Export, it's a snapshot, not a live sync
- With the file download, you upload the file yourself. BCKSTG only sends hashed emails to Meta when you connect your own ad account
- Your raw subscriber list is never shared with any third party
