AUTOID review for Klaviyo: Email Marketing & SMS

Took about 2 months to try and get Klaviyo to integrate with Shopify tags with lots of back and forth between support who weren't able to assist me properly, rather just sending me a link to an article. We were also overcharged for 3 months and still yet to receive our money back. Set up with Omnisend and immediately the integrations of profile data, segmentation and shopify tags were there without me even paying for anything.
