Final answer:
To ensure that your Send Sample Email resolves with tokens correctly, you must select a pre-existing lead with populated tokens, as the data for the tokens is drawn from the corresponding fields in the lead record. Sending the email to a 'Send to' box only or approving the email status will not populate the tokens effectively without a lead record.
Step-by-step explanation:
To ensure that your Send Sample Email resolves with tokens correctly, you must B. Select a pre-existing lead with populated token. This implies that your tokens, placeholders for dynamic content that will be replaced with actual data when the email is sent, need a source from which to pull this data. In most email marketing or campaign management systems, tokens are filled with information from your lead or contact records. Therefore, having a lead record with already populated fields is essential for the tokens to resolve with actual values when you send a test or sample email.
If you send an email using the "Send to" box only, without a lead, there will be no data to fill the tokens with, and they will remain unresolved. Setting the email to Approved status is usually a step needed before sending finalized emails, not test emails, while checking the tokens checkbox may not be relevant unless it pertains to a specific system's method of indicating which tokens to use or test.
