    Lead411
    It is well suited for reaching prospects across a vast array of industries; lead generation, planning for meetings (let's me know who might be attending from the client side and allows me to view their LinkedIn account ahead of time. I wouldn't use it for B2C sales or inexperienced sales support people. One still needs to determine which contacts to download.

    Cons
    Lead411
    • Ability to search contacts and companies by actual street and physical address is not there yet. This is extremely helpful when trying to strategically work a particular neighborhood where you're trying to build up your own individual name and brand recognition. It's also a way of keeping others in the sales force from stepping on the toes or duplicating efforts of another sales rep.

    Usability
    Lead411
    I would rate Lead411’s overall usability a 9 out of 10. The platform is intuitive, easy to navigate, and provides quick access to accurate data. Features like advanced search filters and integrations make it seamless for sales teams. Minor improvements could be made in global data coverage, but overall, it’s highly efficient and user-friendly.

    ZoomInfo certainly is class when it comes to its capabilities. That said, if you're in a heavy outbound role and you just want to get down to the nitty gritty Lead411 is a cost effective measure to get you the information you need to be as successful as you can possibly be.

    Return on Investment
    Lead411
    • I've been able to receive some great contact info that has led to me booking new speakers.
    • I've wasted a lot of time and credits on data that says it was verified and is not correct.
    • It is very labor intensive to keep cost down.
