It's been great. I had one experience with customer support where I felt the person wasn't going to pass on valid feedback (open rates of the first email cut by half due to < 2 hour wait with FB sync). But other interactions with support were great and I also was able to connect with their product manager who promised to look into it. I felt they're a young and flexible team. Also laser focused on email and what email marketers need.

If you want flexibility in segmenting your drips (or flows as they call it) then you need to use Klaviyo. We were using Mailchimp and kept finding areas that made it time consuming, confusing, or just not built to have a flexible drip campaign where contacts receive emails based on rules. For example you can easily create a series of emails that are only sent to contacts that meet a specific criteria and do it all within one drip through a "workflow" like drag and drop builder. You can also sync up to your facebook leads and save money on Zapier which is what you need to use if with Mailchimp.

While Zapier immediately pulls in leads from Facebook, Klaviyo only syncs every 2 hours. A lead getting a welcome email right away is SUPER important, but this means they don't hear from us for some time and it's negatively impacted our first email open rates -- almost cut it in half.

Fantastic from beginning to end. I would suggest Klaviyo to anyone.

There are hundreds of email marketing managers, and they all pale in comparison to Klaviyo. Instead of trying to be a jack of all trades, Klaviyo focused on making the best e-commerce marketing platform, PERIOD. The integration with Shopify is an utter game changer, and makes it possible to actually feel in control of your marketing.

When it comes to Klaviyo, there is a bit of a learning curve. They do make sure there are plenty of resources, so if you want to learn you will.

In August 2015... I was convinced I needed a better email marketing solution with automation. Klaviyo is/was much more expensive than other basic email services (MailChimp, getResponse, AWeber) but the marketing automation was arguably a great investment with good ROI. I integrated K with my site (Americommerce) and discovered that the only way to make K to work was via middleware, "CartSync" which cost about $100/month. It was imperfect. Bare minimum metrics. Marginally useful. I accepted the limitations and launched. Klaviyo support manager's exact words to me were, "Why don't you move to Shopify?" Those words resonated... 10 weeks later when I decided to actually replatform to Shopify, getting Klaviyo support to answer a basic question was a frustrating experience. K support earned a reputation as only slightly better than useless. Then there was the "integration disconnect" bug -- the connector to my Shopify store was shut off by Klaviyo, without notification -- ah, but there was an email -- sent by a spammy server (non-transactional) that never saw the light of day. We learned that K was sending TRANSACTIONAL EMAILS from a marketing server. And this email was getting flagged as spam by many mail servers. In the mean time, I was a presenter at am ecommerce conference and when I asked who used Klaviyo, many raised their hand... then I asked, "is anyone satisfied with Klaviyo support?" -- the room's reaction caused the Klaviyo rep in the room to text his management team - and before the end of the session we were told K was hiring 4 new support reps. SO the consensus was: Klaviyo usually works great Klaviyo has lousy support Klaviyo is relatively expensive as your customer list grows Klaviyo is very powerful. But Klaviyo *had* an issue with their email hitting a spam RBL... When I went to send a preview email for a campaign, it was flagged as spam. When I tried sending Klaviyo subscribe emails from 10 different stores that I knew to use Klaviyo, they all went to SPAM. I was able to get Klaviyo removed from the offending RBL - but until a call from Klaviyo's director of product at T+30 hours, the silence from Klaviyo was deafening. Then Cyber Monday's failure... I'm still a K customer for today, but I will probably not be a customer in 60 days. I still think the product is amazing, but no-confidence in deliverability and the history of limited support forced me to seek an alternative.

Incredibly powerful rules and automation flows. SUPER TIGHT integration with Shopify.

Deliverability is a concern. Support is slow to respond.

Good for analyzing first part data.Pretty good integration system with e.g. Shopify, Facebook etc.

Css editor is okay but would need additional software or programming skills to make high class emails.
