Switched from MailChimp to Klaviyo and haven't looked back. It integrates really nicely with Shopify and we're now able to do SO much more to support our E-Commerce desires.

Excellent app for the last 2 years but this business of limiting emails hinders the performance of growing stores. They just don't seem to get it you will be resending your emails to the same people who only engage but never buy. After 10+ years of doing this, you need to hit the fresh inbound emails more frequently. I am leaning towards moving on if this hinders my business growth. It seems there are better options now than from 2+ years ago being on Shopify.

Pretty fantastic but can be damned intimidating-- especially if you've invested a bunch of time in the past to learn other email systems and figure this one will be as hard or harder. We became Klaviyo users in 2020 but didn't do much with it until the last 6 weeks. We tried but got stuck a lot. We attempted to hire Klaviyo experts but no one wanted to work hourly ad we didn't want to sign contracts for thousands of dollars per month and nothing really guaranteed from a completion standpoint. In the last 6 weeks we've realized how much Klaviyo can do-- and figured out a LOT of the "how" to get it to do that just by methodically going through the video trainings on Klaviyo Academy. Those videos are a lifesaver! If you've considered giving Klaviyo a chance because you suspect it might do a bunch of great things you wanna do but don't know how-- but have held off, thinking it's "too complicated" to learn...give yourself a chance. We haven't figured everything out by any means but we're well on the way to Klaviyo paying for itself and becoming a magnifier and amplifier for all of our channels and audience growth plus of course revenue growth. FWIW the Shopify integration was trickier than they said it would be-- but all in all not horribly difficult.

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.
