Muy útil con sus flujos de correos automatizados y campañas para temporadas especiales. Se pueden combinar con flujos SMS.

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.

This is absolutely, hands down, no questions asked...the best email marketing software out there. If you're not on Klaviyo...I don't know what you're doing!

Klaviyo is overall not reliable for our company. The analytics have incorrect Klaviyo revenue attribution as it doesn't filter out our Amazon sales that's integrated through Codisto. Also, the way they do their billing based on "active profiles" is very strange and frustrating to have to manually maintain. I wish they'd just have simple billing based on number of emails sent or total subscribers. We are highly considering a different email platform now as many others have evolved more in the automation flow builder space.

Really good app overall! A bit expensive but you'll make a profit quickly. We are happy that there was a free option at the beginning.
