Daily incessant sales team doesn't know how to go away despite telling them to go away multiple times and remove me from all communications. Worse company in the WORLD, I cannot stress DO NOT USE THEM. Go to Mailchimp or ANY OTHER PROVIDER.

Klavyio is a small piece of .... they let you make all the set up and when they see that you don't upgrade their plan they block you account. Big loss of time

Very disappointed. I am actually thinking of cancelling this service because of this. I created a list to suppress profiles so that we can stay in the lower profile account, since their plans are based on how many active profiles you have. The lists will sometimes expire randomly and auto bump you to a much higher plan and charge your card immediately. This is very frustrating and I have to get on with support in order to try and get a refund. They really need to do something about this.

Klaviyo’s pricing policy is unethical and exploitative, profiting off bots and spammers by inflating active profiles, leading to outrageous overcharges. Literally, a $20/month subscription can turn into over $500/mo within days thanks to their scammy dynamic pricing tiers. Yes, each bot visiting your site WILL create an active profile in Klaviyo, with or without event tracking from your website and Klaviyo WILL bump you up pricing tiers without your consent. When confronted, they refuse to acknowledge or address customer concerns. They happily treat customers like cattle, milking them for profit without accountability or remorse. Avoid Klaviyo at all costs!!

De afgelopen weken is onze ervaring met jullie sales- en onboardingproces bijzonder frustrerend geweest: Agressieve salesbenadering We werden herhaaldelijk benaderd – niet alleen ikzelf, maar ook enkele collega’s – tot op het punt dat het als opdringerig en storend werd ervaren. Hoe jullie aan hun telefoonnummers zijn gekomen, is ons een raadsel. Misleidende beloftes bij onboarding Er werd ons geen gratis maand implementatie-ondersteuning beloofd, dit kon echt niet want het was “plug-and-play”. In werkelijkheid ben ik inmiddels al ruim 2,5 week bezig zonder dat het goed werkt. Niet-beschikbare implementatiecontactpersoon Onze toegewezen contactpersoon is geregeld meerdere dagen onbereikbaar, waardoor we telkens stil komen te staan op cruciale momenten. Onwerkzame supportkanalen De reguliere support verwijst ons steeds naar artikelen en stappenplannen die elkaar tegenspreken. Ondanks meerdere verzoeken om telefonisch contact om dit op te lossen, blijkt bellen ineens niet meer mogelijk. Als dit vandaag niet wordt opgelost, overwegen we serieus om de samenwerking stop te zetten en een alternatief te zoeken.

ITS A SCAM! They keep charging us money while I do not use their service. Tried to contact them many times but just do not reply in a way that helps (only standard answers no solutions) Hereby my last email to them: Hi Klaviyo, I wrote you guys multiple times allready You keep charging us while we not use your services In the attachment you find the transactions We dit not authorize these and we do not use your services. I filed chargebacks allready Also I am going to inform financial regulators about your doings. This is not acceptable. Please confirm refund of these payments and please stop charging I do NOT have a login, i do NOT use your services and I do NOT want to use your services. This is an absolute scam Do not ask me for usernames and that kind of stuff. I do not know a username because I do not want to be your client. Multiple times I informet you about this allready but no action is taken. If I do not get a confirmation within 24 hours that this 'subscription' is ended and the amounts will be refunded I will place reviews everywheren and inform press about your wrong doings With the payments attached you have the info you need to end this
