I have 7 prospecting productivity tools integrated with my Gmail or Chrome extensions. But when it comes to getting verified emails, I resort to LeadIQ.
So far, they've had over 80% verified emails rate compared to the likes of other newbies coming every day or players who've been at this for a while now.
The default list building process is very efficient and makes is easy to search for your past prospects in case you didn't take note of their email then and there.
I haven't had a chance to use their premium version with verified phone numbers but so far if I had to recommend someone a tool to get correct emails, LeadIQ wins by a landslide.
No more second-guessing your prospect's email address.
The fact that when you click the LeadIQ chorme extension button, it populates a new page of the profile eats up my RAM and seems a bit inefficient as other tools have integrated it on the original LinkedIn page itself.
Recently I got an email from LinkedIn asking to uninstall their extension. LinkedIn threatened to sue Hunter and I guess they're aggressively going after the companies who're putting an extra load on their servers.
There's a plethora of prospecting productivity tools - Saleslift, GetProspect, Hunuter.io, etc. But LeadIQ has had over 90% rate for correct lead data. Thus it wins over the others.
