Easy to integrate into Shopify website! I'm new to email marketing so understanding the bigger potential picture is challenging buy Klaviyo makes it fairly easy to learn.

Shocking customer service from the douchebags at Klaviyo. Been with them for 3 years now. Generally all ok. However we've recently reduced the number of contacts/profiles in our email list quite significantly (by around 50,000). We expected this to have a significant effect on our monthly bills, but it seems Klaviyo is still taking out the same monthly amount as they were prior to the reduction in profiles.

I've spoken to them via live chat and email today, and was told that Klaviyo does not automatically adjust its billing down if the amount of profiles is reduced. Convenient. They were capable of automatically increasing our bills when our profile list was growing. But apparently they don't do this when the profile lists decrease.

Even so I thought that once I'd pointed out that we did reduce our list size last month, and therefore this month's bill should be significantly smaller (by about $550), they would agree to refund me the difference, but they basically told me to check my terms and conditions and get lost. They wont refund me the difference.

I am pretty dumbstruck by this. This seems very underhanded to me. Even if it's in the T's and C's to not do the right thing here stinks.

Obviously they've now lost all of our business.

Klaviyo has the best support system of any platform I've used. They're incredibly attentive and always provide clear, helpful assistance. I wish every B2B platform was as efficient!
