How does personalization work?
Personalization happens within Campaign Monitor via custom fields. Our integration allows you to map Salesforce data to Campaign Monitor custom fields. Most customers use our import wizard in-built field mapping feature to add subscribers and map to custom fields.
If you use one of our other features to add Salesforce Contacts or Leads to Campaign Monitor, you can use the field mapping feature. Once the data is added to Campaign Monitor, you can use custom fields to personalize your emails. This article from our friends at Campaign Monitor shows how.
