An ecommerce brand on Klaviyo doing about $3.3M a month ($19.8M over roughly six months). Email only; text messaging is not set up on the account.

Total revenue held roughly flat while Klaviyo revenue grew 22%, so email took a larger share of sales. Almost half of revenue came from one owned channel, split close to evenly between automated flows and sends. With SMS not yet set up, the account still has an unused channel.
Calls are for stores doing $20k+ a month.
