Reducing your bounce rate in Pardot

Written for B2B teams running Salesforce-native marketing automation.

Pardot
Their stated thresholdSalesforce's guidance for Account Engagement points at bounce rates under 2%, with deliverability support for accounts running their own sending domains.
What happens if you cross itSupport is contractual and consultative. A list quality problem becomes a conversation with your account team rather than an automated restriction.
Where the bounce data livesThe email report for the send, and the prospect's activity history for the individual bounce. List email reports separate hard and soft bounces.
How bounces are classifiedPardot marks a prospect undeliverable after a hard bounce and after repeated soft bounces, and the prospect record carries the history so the reason is visible on the record sales is looking at.

Bringing the rate down

Each step is an action inside Pardot, in the order worth taking them.

  1. Segment prospects by the bounce on their record

    A dynamic list on mailability status gives you the set. Adding the prospect source shows where they came from.

  2. Check whether the address came from Salesforce or a form

    Pardot prospects arrive from forms, imports and the Salesforce sync. A sales-entered address in the CRM is a different problem from a form fill.

  3. Talk to sales before deleting anything

    Prospect records map to leads and contacts that sales owns. Deleting a record because marketing cannot mail it is rarely the right call.

  4. Add validation to Pardot forms

    Form handlers and Pardot forms accept format-valid addresses. A check at submission stops the junk becoming a prospect and a CRM record at once.

  5. Store the verdict as a custom prospect field

    That gives both marketing automation and Salesforce reporting the same fact to act on, rather than each inferring it separately.

The mistake people make here

A bounce report mixes two causes that need opposite responses: addresses that do not exist, and receivers refusing mail they could have delivered. The first is fixed by checking the list. The second is a sending problem and no amount of cleaning will move it.

Questions people ask

What happens to a Pardot prospect that hard bounces?

It is marked undeliverable, marketing email stops, and the bounce appears in the prospect's activity history where sales can see it.

Does deleting a prospect remove the Salesforce record?

No. They are separate objects joined by the connector, and deleting the prospect while the lead survives means the sync can recreate it.

How do I stop sending to undeliverable prospects?

Pardot already does. The useful work is finding out which source produced them and stopping that, rather than managing the suppression.
