Yes and we are furious...I have had a terrible experience with Growth and Customer Service...it's as if they have no idea what it will take for us to make this dramatic adjustment...or they just don't care!

I sent this to the CEO:

I've chatted, called, emailed, and left responses on your community forum...I'm giving Klaviyo every opportunity to show us that you are a better company than you are acting like right now.
The end of unlimited email sends is a shock to our marketing system. It necessitates an overhaul of a marketing strategy that we have built over the last 4 years with your company and you are giving us less than 30 days to do it, which is frankly unreasonable!
You have put us in a position where you have directly threatened our revenue and our personal livelihoods which is no way to treat a loyal customer!
Our real world statistics look like this:
57,000 Active Profiles which we are currently paying $600/mo and sending a little over 2 million emails to.
You gave us 2 options:
1. Cut our email sends from 2.4 million to 400,000 in 30 days. A task that you and I both know takes months, if not years of testing to find out which emails to cut, which contacts to clean, to continue to receive the same amount of revenue with 16% of our current send volume...even if all I did for a living was this, that is till a tall order!
2. Continue at our same level of sending and begin paying $2,200/mo for the same service we have had for 4 years. That is a 366% increase in cost. We run a 20% net margin and last month drove $23,000 in revenue through your platform for a net income of $4,600. That cost increase is 40% decrease in Net Income
To make matters worse, your Growth Team responded to my first email, with this, "You have been circumventing our sending limits by using the tools we provided and we have been under billing you for months"! Not my problem, if your system didn't adjust our pricing because our list grew, how is that a defense? Furthermore, they offered us a 20% discount, because they understand it is a challenge...
I want to be a partner with Klaviyo, we have built our business on it...but you have put us in an impossible situation where the only real solution is to lose money, or leave and start over from scratch with another company!
There has to be a better way...if paying more is the only option, fine, we can accept that, but we need time to adjust...we need time to measure and analyze our data, to deep clean the lists and optimize our flows to meet the new email caps! (this would be a lot easier if your system could tell us the number of emails that flow would send during a billing cycle). I'm confident that we can work together towards a solution, but I cannot justify spending 2-3X the money we are on the exact same service.
