• The unique identifier type cannot be changed after a subscriber has been added to your campaign

Selecting a Unique Identifier Type

Verifying the Unique Identifier

After selecting a unique identifier, you will want to consider enabling the verification method. Subscriber verification is important for security reasons to ensure only real people are signing up for your campaign. These are your options:

Verification Options	Verification Behavior
Require Verification	The subscriber will be considered verified and added to your campaign only when the unique identifier is confirmed.
Require Primary and Secondary Verification	The subscriber will need to first confirm the primary verification method and then the secondary verification method (the subscriber will be considered verified and added to your campaign only when both are confirmed).
Disable Verification	No verification method will be triggered, the subscriber will be added without any verification (unique identifier is still a required field)

If you choose to verify the unique identifier. Please read additional material on your selection:

• Email Verification: Sending the confirmation email

• Phone Number Verification: Sending an SMS message

• Crypto Wallet Address Verification: Connecting crypto wallets
