Why people leave Klaviyo
Klaviyo is an email and SMS marketing platform priced by contact count, listing from around $45/mo for roughly 1,500 email contacts and rising steeply with list size. That is roughly $540 per year — about $2,700 over five years — and access stops the moment you cancel: the fee is for permission, not for ongoing work done on your behalf. The tools above do their slice of the job on your own hardware or your own server, so the cost is fixed at the sticker price.
