Letterhead's Recipient Validation

Recipient Validation is a built-in feature that helps ensure your subscriber list stays clean by verifying the validity of new email addresses.

✅ What It Does

Once enabled, Recipient Validation runs automatically as a daily background process.

Here’s how it works:

• Automatically Validates New Subscribers
  Any email addresses added via import or through your archive page will be automatically checked and validated before being added to your audience list.

• Runs Daily
  The validation process runs every 24 hours and only targets subscribers that haven’t already been validated.

• Reduces Risk & Maintains List Health
  This helps prevent sending to invalid or mistyped addresses, which can harm your sender reputation and increase bounce rates.

🚫 What It Doesn’t Do

• Custom Signup Pages Are Not Supported
  Validation does not apply to email addresses submitted through custom-built signup forms.

• No Re-Validation of Existing Subscribers
  Once a subscriber is validated, they are not re-validated in future runs. Only new, unvalidated entries are checked.

💡 Why Use It?

Enabling Recipient Validation helps:

• Improve your email deliverability

• Protect your sender reputation

• Avoid sending to invalid or fake addresses

• Reduce bounce-related suppression and email delivery issues
