With their pricing changes, we have to pay TEN TIMES more than before. I received this message four days before the new price change.

Thank you for your feedback! Klaviyo exists to help you to understand your customers and drive growth from those relationships. If you have profiles that you are not emailing, we highly recommend that you suppress them. You do not pay for suppressed profiles, but you maintain the data so that you can unsuppress profiles in order to send communications to them at future times.

If you prefer to keep them active, the Appreciation Discount that we’re offering to many loyal customers limits the email plan spend increase to 25%. We encourage customers to look for additional communications sent on Jan. 21 to best understand how these changes impact their specific plan and to understand our new flexible pricing features, including auto-downgrade and Flexible Sending.

Lots of cool templates available to help you get started right away with your email marketing. But I use mostly for segmenting customers, immediate thank you notes for new orders, and customized abandoned order email. The flows are easy to modify. The analytics are clear. I have yet to fully maximize Klaviyo but I am happy thus far. Oh and the support is excellent!

Klaviyo support is the best! I've never waited long and the agents go above and beyond to be helpful.

It makes a world of difference when you need help!

We've been using Klaviyo for close to 1 years now on our website and are very happy with all the features included. Pretty easy to use, and great documentation and video. ROI through the roof!

I am phasing Klaviyo out of my stores because it significantly slows them down, hurting SEO, and cancelation requires an email, the address for which they do not share on their site.

**September 2023** Customer service became so slow AND NOT wiling to deep-dive to help, just to close tickets**
I have realized I lost thousands euros, thousands!! In people not being able to go properly into the welcome flow. I have raised concerns, but support answered there were no issue. I decided to try by myself with a new mail address and I haven't received the welcome mail! I was right, and I had to be extremely pissed towards the support so that they decided to escalade the issue internally, explaining that indeed there was an issue, but the pain is here, thousands euros lost in welcome flow. My business is at risk, terrible.

Sorry to hear you're having troubles, the team has reached out to get all of this resolved!

Klaviyo's UI is a bit more well-designed and usable than Mailchimp. We switched in order to be able to have more flexibility for what Klaviyo calls "flows" and Mailchimp called "automations".

It's definitely not great though. There are lots of insane caveats. For example there's no way to click on a user and tell where they are in a flow. And there's no way to add more content to the end of a flow and just have it automatically go to everyone that should be sitting and waiting at the end for more.

When we test our emails with mail-tester.com they almost always get flagged with Klaviyo having an IP address in one or more blacklists. Mailchimp never had that problem.

Klaviyo also pointlessly requires a Captcha on every single login.
