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

• Validates New Subscribers Automatically
  Email addresses added via CSV import, embed form, or your archive page are automatically checked before being added to your audience.

• Runs Daily in the Background
  Validation occurs every 24 hours and targets only unvalidated emails.

• Improves List Health & Deliverability
  Helps prevent sending to mistyped or fake addresses, protecting your sender reputation and reducing 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
  Existing validated subscribers are not re-validated. Only new or unvalidated entries are checked.

Where to turn it on?

Organization-Level

When enabled at the organization level, Recipient Validation applies to all channels under your account. This is a good option if you want list protection across the board without managing settings individually per channel.

Channel-Level

You also have the flexibility to turn on Recipient Validation for a specific channel only. This is helpful if you want to test the feature on one channel first or only validate emails tied to certain newsletters.

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
