I picked up Closely from AppSumo mainly for LinkedIn outreach and contact discovery, and honestly it does the job pretty well.
The LinkedIn automation features are straightforward and easy to set up. I like that you also get monthly contact credits for finding emails and profiles, which makes prospecting faster without jumping between multiple tools.
The interface is clean and not complicated, so even if you're not very technical you can start campaigns quickly. For agencies or people doing B2B outreach, it can save a lot of manual work.
What I like most is that it combines LinkedIn automation and contact discovery in one place. That makes it useful for lead generation workflows.
Overall, a solid tool if you're doing LinkedIn prospecting or outreach regularly. Definitely worth considering if you grabbed the AppSumo deal.
