User.com

If you know basics of Google Tag Manager, User.com is a very flexible tool that can broaden your range of possibilities when it comes to marketing efforts. For marketing teams in startups, it's a great way to do more things without waiting for IT team to do it for you.

Some features aren't so flexible as they could be.

It surely offers a lot of functions - chat, email campaigns, CRM, marketing automations. It has potential to became an all-in-one platform. Support team, yep, UserEnagages support is AWESOME. Other companies could learn from them.

UX is simply TERRIBLE, to tell the truth it took me a lot of time to get around some features like sending email campaigns. Mobile app is almost non-functional, so it is safer to assume that there is no mobile app. Web app is SLOW, terribly slow. Chat has a lot of bugs, sometimes it is hard to get ahold which conversation is new.

Feature-rich software with great automation potential and superb support team. I was impressed when their customer success officer noticed a technical mistake in my automation setup, notified me, and fixed the issue before it messed up my email campaign.

User.com automation may be difficult to configure as you need to plan the whole flow ahead. It's not as intuitive as on Intercom, but it can automate more processes in your team and provide you with more insight into the relations with your customers and users.
