Insert lead fields
Use merge fields such as {{first_name}}, {{last_name}}, and {{company_name}} where you want a lead value to appear.
Identify a recipient from a link
Add {{recipient_id}} to a link parameter when your destination needs to identify the lead, for example ?utm_content={{recipient_id}}. The value is a stable identifier, not the recipient's email address.
Add random alternatives
Write alternatives inside one set of braces, such as {Hi|Hello|Good day}. Each sent email chooses one option. End the block with |, as in {Hi|Hello|}, to also allow no text.
Use multiple blocks
Add as many random blocks as needed in a subject or email body. For example: {Hi|Hello} {{first_name}}, how are you {today|doing today}?
Preview and test
Use Preview template and send a test email before launch. The preview consistently shows the first option; sent messages choose their alternatives when they are prepared.
Personalize campaign email copy
Campaign copy can combine lead fields with simple random alternatives, helping each recipient receive a natural variation of the same message.
