Shocking. Absolutely shocking. My account was suspended out of the blue, with no warning, no explanation, and no support. I’ve spent hours crafting newsletters, building campaigns, and hundreds of pounds on social ads to grow my audience... and Klaviyo just nuked it all in a second.I’ve done nothing wrong. No spam, no violations, no shady behaviour. My campaigns were entirely legitimate, yet my account, and my business communication, was halted instantly.Customer service has been near nonexistent. Automated messages, no timelines, no clarity. The entire experience is infuriating and unprofessional.If you run a business and value your time, your work, and your customers, do not trust Klaviyo. One day they’ll just delete everything you’ve built without reason, and there’s nothing you can do about it. One star is far too generous for this.
