From Marketo, under Admin > Integration > Salesforce, select to start Salesforce sync.
Log into your Salesforce account. This will initiate field mapping.

Select to Edit the relevant Marketo email.
From the email toolbar, select the Insert Token icon.
Select the token relating to the field name synced from Salesforce that contains the Calendly link.
Set a Default Value. Options such as a routing form or a round robin link may be ideal.
From the email toolbar, select the Edit HTML icon.
Locate the personalization token in your email, then add <a href=" before the token and "> Book time here. </a> after.
Replace "Book time here." with the text you want to be hyperlinked.
Save changes.
Preview the email to make sure your token and default is working as expected.
