Frequently Asked Questions
Is this the same as Mailchimp marketing?
No, Mailchimp Transactional (formerly Mandrill) is a separate product for transactional emails. Regular Mailchimp marketing campaigns use different webhooks.
What's the difference between reject and bounce?
Rejects happen before sending - Mandrill blocks the email due to policy. Bounces happen after sending - the recipient server rejected delivery.
How do I track campaigns in Mandrill?
Use the metadata field when sending emails via API. Include parsebounce_id in your metadata for campaign tracking in ParseBounce.
Do I need the webhook key?
Yes, the webhook key is required for ParseBounce to verify that events are genuinely from Mandrill and haven't been tampered with.
