1) Outreach is EXTREMLY slow and inefficient. Simple actions require multiple clicks, and each UI update take 2-7 seconds to happen. Can't roll through a prospect list and call each person on the sidebar. You have to go in and out of each lead's page.
Examples: Changing numbers requires a page switch(rather than sidebar edit). I want just call tasks, but it kicks me over to different task types, and tasks take FOREVER to work through. I want to leave a task and go to a different lead, but the task sidebar stays open, and when I close it the page forces me back to the lead for that task. That just scratches the surface.
2) Ineffective integrations. No Integration with LinkedIn so URLs and titles aren't updated, URLs not even mapped when we prospect from ZoomInfo or Salesforce, so I have to manually input for every lead(another page switch). Chrome Plugin breaks a lot. No Hubspot integration.
3) Bug City. Expect it to break and crash in every way imaginable, and be ready to spend a lot of time going back and forth with their support.
Conclusion: Their marketing very well and probably paying for good reviews, because anyone I talk to who's used a different sales engagement platform like SalesLoft or Apollo agrees that Outreach is the absolutely the slowest, most poorly built product in the space. I've used SalesLoft and Apollo at previous companies, and my workflow was at least two times faster. Review collected by and hosted on G2.com.
