Klaviyo: Email Marketing & SMS

And you are out in the desert ...alone. Their double opt in doesn't work since weeks. Customer support isn't helpful at all. No, even worse: they just denied this fault. Only after I paid a developer who confirmed the Klavyio system having an issue, they admitted there is a bug. Huh.
And then....nothing happens.
Customer support confirmed the bug as fixed. But - what a surprise - it is NOT. No further answers from customer 'support' . I worked on that issue now for several days and just let it go now. Horrible experience. Never again! And: that's a pity, because the features would be nice. Handling too. But if you are impossible to follow the legal requirements and lose leads 't get any help from customer support - its just crap.
