Intercom

Basic

UX is terrible, even for experienced support people it's hard to navigate or find something, yes we used Intercom and Zendesk so we can easily compare them;- complicates very simple processes, so we always had to look for ways to overcome them or spend much more time solving them, instead of focusing on providing excellent support to our customers;- it provides so many features, but they are all basic or limited, so we usually had to think about how to create another workaround for the missing thing in User.com instead of doing our job;- hidden charges for attached files in letters/chats, this information is not on their pricing page.

Integration with mobile phone             

User.com is easy to use and what we like most is the way they show the whole chain of sales opportunities + good customer contact and many features included like chat, provides us with 5 star experience.

Frequent technical glitches

Digital Producer

The Klaviyo visual builder is buggy, even in their "NEW" builder there were bugs with things as basic as applying link colour styles at a global level.

Designer & Owner

It does have bugs sometimes and after the latest release of the new editor, there's an issue with previously saved blocks not working in the new editor.

71% of reviewers feel negative about Klaviyo’s bugs and issues. Reviewers report experiencing frequent glitches, slow performance, and editor bugs that disrupt their workflow. They say the visual builder sometimes freezes or fails to apply changes, causing frustration and lost time.

Users find managing large flows challenging due to lag and occasional broken links. They also mention difficulties with customer support responsiveness when technical problems arise, which compounds their dissatisfaction with ongoing platform reliability.
