An ecommerce brand on Klaviyo doing about $2.2M a month ($13.4M over roughly six months), using both email and text messaging.

A 44,309% rise means the previous period had very little Klaviyo revenue, so the percentage says more about the starting point than the run rate. The useful numbers are the split: 77% from flows means most of this revenue comes from automations that run without a send calendar, and SMS at 41.92% shows text can carry close to half of owned channel revenue. At 17.78% of total, there is still room for the share to grow.
Calls are for stores doing $20k+ a month.
