I used Klaviyo for years between 2018-2020 and I was happy with it despite the high costs. More recently they introduced caps on how much you can email before going to the next tier, and their caps are extremely restrictive compared to other ESPs. In order to send 5 emails a week to my entire list costs me double what I'd pay in my tier normally. So for 2000 contacts I'm paying $100/month to send what I want to send. I'm not against a (good) company making money, but their cost is roughly $1 for 10000 sends and they charge you 20x markup just on the sends. This is absolutely ridiculous and their prices don't justify this when you have better and cheaper options available. I'd stay far away from them.

Expensive hidden costs. Unsubscribed and uninstalled a long time ago but they keep sending spammy emails saying 'account limit reached'
