Klaviyo: Email Marketing & SMS

I rarely (if ever) leave reviews, however the Klaviyo platform has really impressed me. We switched from Mailchimp nearly 12 months ago and have never looked back. Mailchimp is great if you are just getting started, however Klaviyo offers unrivalled levels of customisation, targeting and granularity. I have yet to find something I am unable to do via Klaviyo. When using Mailchimp I was always held back by the system, whereas when using Klaviyo I am only held back by my creativity or lack of skills (which the Klaviyo support is very useful for!).
