Klaviyo: Email Marketing & SMS

I have been using Klaviyo for a month now and I like the concept behind it all however there have been several glitches that I have had to contact customer services about. When I have spoken to customer services, it has taken ages to get them to understand the problem and it has been very frustrating at times. I currently have a pretty significant problem that the technical team are looking at. I will continue to use it for the time being and hope the glitches don't affect my sales and reputation as they currently have been.
