SugarAndVapor review for Klaviyo: Email Marketing & SMS

BE CAREFUL TO UPGRADE YOUR PLAN! The plan cannot be canceled because you have to submit a form for cancellation. Then no one will reply to you. Their customer service is zero and totally waste your money. I've paid $700 a month and a lot of time to setting up. The result is frustrating. So I submit the cancellation one week before the new billing cycle. Guess what, NO RESPONSES UNTIL NOW. So I have to pay for next month!! AWFUL APP I'VE EVER SEEN
