Product launches

• Email addresses now support default warm-up schedules. When email addresses are provisioned, they enter a warm-up schedule that changes their daily sending limit depending on the number of emails they’ve sent. This protects SMBs from landing in spam while also growing their capacity to send marketing emails automatically
• UTM parameters — Emails sent as part of campaigns, triggers, or email blasts now automatically inject query parameters onto all links contained in the email, a la ?pf_customer_id=, ?pf_business_id=, ?pf_campaign_id=. Use these parameters in tandem with your booking links to track the source of bookings and drive ROI calculations for the SMB’s marketing efforts

Improvements and changes

• Serialization failures, e.g. when two different API calls attempt to modify the same object, now raise a 409 Conflict error, indicating that they are freely retryable. Before, we returned a 422 Unprocessable Entity error, which made the error appear identical to actual validation errors
