Differences Between HML Merge Fields and PML Variable Tags in Account Engagement

Formatting

• With HML, modifiers are not necessary for merge fields contained entirely in links, and so are not supported. For example, this doesn’t require a #url modifier:

www.pardot.com/｛{Recipient.FirstName}｝

• HML doesn’t use address line tags like %%address_one%%. Instead, HML combines any data you may have for address lines 1, 2 into a single street address merge field, which applies to account addresses, billing addresses, and shipping addresses:

｛{Recipient.Account.BillingStreet}｝

• There’s only one HML signature merge field and it will render depending on if an email is HTML or plain-text. PML has separate tags for the HTML and plain-text versions of an email.

Limitations

• There’s a limit of 200 HML merge fields and 10 pieces of dynamic content in an email or email template. If you’re upgrading an asset that exceeds these limits, we’ll ask you to remove some PML tags before we can convert it to HML.
