To be fair I haven't had any experience with tech support yet. But have been using it for 2 years now and overall Im a big fan. Now that I compared it to GHL. They are different cos GHL is more of a CRM, but in terms of email campaigns and flow and integrations with Woocommerce Klaviyo has so much better interface and ease of use. Will update my review if things change

Klaviyo support is next level! I always get put in contact with the most skilled, understanding and patient product experts. Most recently, Luan was extremely helpful and went out of their way to find a solution to my challenge. Thank you again!

✓ Great onboarding experience with the experienced Marius - who was thoughtful and helpful in his responses ✓ Wealth of support documentation ✓ Wealth of best practice guides ✓ Feature-rich platform for omnichannel marketing ✓ First-class integration with Shopify You have to show up prepared to do the work. Nothing is turnkey. But this platform is best-in-class.

Great for drip campaigns. We use Klaviyo for the onboarding of users - it put them in a 5-email sequence drip campaign. Additionally, we're able to use the API to put users in a separate user journey based on conditions within our site. The campaign builder is clean and straightforward. We plan on staying with them for a long time.
