Klaviyo: Email Marketing & SMS

Installing this app was the root of all disasters, basically no service, brought my website down, lost thousands of dollars in ad dollars, my website was grayed out and stuck, couldn't click on any pages, the fees were extremely expensive, When you increase email activities, he doesn't even have any reminder to increase the fee, and directly upgrades your fee in the bill. Rogue behavior, opaque charges, stay away from klaviyo, is away from disaster.
