Simply the best! We switched from omnisend and find it much easier to work with. Should have gone with my gut and implemented Klaviyo in the first place. Super responsive support as well.

Customer service sucks!!!! Repeated emails for the same problem still can't be solved. Live chat takes a long time for someone to reply every time!

It purely and simply makes a considerable difference. After going to war with fb ads and gaining some clients, its good to relax with a trustworthy email marketing tool

So far so good. I switched from Mailchimp and I'm really liking the experience so far. A couple pros is it lets you send a campaign based on the subscribers time zone. It is also pretty easy to get your flows setup like abandoned carts. The drag & drop editor is pretty nice. I'm liking it so far.

The gold standard when it comes to e-commerce marketing. We've used a few different companies before, if you're selling physical goods, Klaviyo is the best hands down.

Best thing I ever did! The data and insights on customers is amazing, and the ease with which I can create templates - O.M.G
Love it!

If I could give zero starts, I would. It's an amazing app, but they want to control your email domain and the way you email your clients. Not very versatile. They steel your money very easily with their automatic upgrades as well.

Customer service is TERRIBLE! Also, Beware if you use their SMS, you are putting your company at compliance risk. This last issue is our final straw with them. They locked (disabled) our account automatically for uploading a list of email addresses that were legally collected from an event we were involved with. So if you don't mind risking your account being shut down until one of their "customer service" reps gets to your ticket within a few days, by all means give them a try. If you want to have a reliable e-mail service, I'd recommend looking elsewhere.

Hey, so sorry to hear this is happening. Our team has taken a look at your account to figure out what's going on and should already be in touch. Hopefully we can get this sorted out for you asap.

Double opt in on free plan means you will have no sign ups. And there is no way around it. If you have a 3rd party sign up form (like Privy) Klaviyo will still send a sign up confirmation request once the address is synced to the list.
I don't mind paying for a good service, but not to a company that messes me up in such a sneaky way. Will sing up for a paid plan elsewhere.
