Klaviyo: Email Marketing & SMS

Signed up to this last year and although for a small business it seems expensive you do get a lot for your money. It does so much more than what my Shopify emails could in terms of segmenting and reaching different customers. There's also lots of benchmarks, metrics and reports to help you analyse what's working and what's not, although I do need to get my head around them. Plenty of tutorials to help you and also educational webinars. The support team are also on hand and reply very quickly.
