Klaviyo does an excellent job on guiding my business to achieve its destination toward success. A clear and precise explanation through it's tutoring simplicity reveals the quality of expertise it offers to VIP Communities.

Really disappointed that they got rid of unlimited emails. We send 1-2 per week, and they have priced themselves out of the market. Emailed the support team about the price increase and they did nothing. It will now cost me an extra $250 to send fewer emails than I was before. I also found that their editing tools were more archaic than other companies I have used.

Hi Lindsey, thank you very much for taking the time to write a review about your experience with Klaviyo. I’m sorry to hear that you’re unhappy with the email limit that applies to your tier. We apply a limit to encourage customers to send timely, targeted emails to their lists and use data segmentation to ensure that messages are relevant. I’d like to ask our customer success team to reach out and give you some tactics for reducing volume, if you’d be open to having a conversation about this. They will be in touch shortly!

Switched over from MailChimp toward the end of last year. It was a very big undertaking recreating all of our email flows, triggers, and templates - but in the end it was well worth the effort. Now we feel like we have a true CRM + Email + Metrics system that allows us to have a much more holistic view of our store and customer that we didn't have before. The ability to slice and dice data is also leaps and bounds better than MailChimp. Finally, even though doing a migration was a PIA, it also gave us an opportunity to re-look everything and button up trigger/DRIP/automation campaigns and fix issues and make things even better.

The text constantly comes up different when we are doing a test for a newsletter(sent to mobile devices) also when doing a pop up form it comes up with an error "Unable to detect that signup forms are successfully installed on your site." even though we have integrated Klaviyo with Shopify. we contacted customer service twice through email a few days ago but no one has responded. The customer service is not reliable.

Hello I left a bad review as I didn't manage to get support, then they contacted me and explained that they had an higer number of request this last days, so they gave me a fantastic support to fix my issue. Thank you again Tracy for your great support. The app is anyway very very good, maybe a little old style design, I can't compare with others, but I chosed it because of the features it has.
