I'm a freelance copywriter contacting over a hundred prospects a month to ramp up business. I'm on a pretty tight budget so I looked for the free plugins first, then the cheap paid ones. It took me three days to even find Lead411 mentioned in passing online (that needs to change, and as a B2B writer, I'd love to help!). I trialed it once and immediately had to have it.
The Google plugin actually works unlike some of the free and paid ones I tried.
The daily leads are great opportunities to reach out in a timely fashion when a business change occurs.
The information is up to date and is constantly updated. It's free to get the lead information, but costs extra to import leads to your CRM. I choose to manually import to my CRM, since I do everything on a manual level anyway and refuse to mass email new contacts.
The video guide clips in the advanced search feature is an awesome touch--it goes through every detail of the incredibly granular search function; I haven't had a question about it that hasn't been answered just by clicking the question mark.
And the search function is everything I could hope for. It has the general selections for industry codes, titles, and revenue, but also has the option to search for particular types of press-worthy events that occurred during a certain time period.
After you've searched, you can save it. So you can return again and again to your tailored list or lists, and your list is not static. Select a prospect and not only do you get all the contacts and contact info available, a summary of the company itself, but also its current revenue and technology stats, job listings, and press events.
Jill Konrath's ebook was also rather inspirational as I started my search for new leads, as well. Again, I'd love to see more content soon...
The fact that I have to pay to import. I'd be happy with free imports up to a certain number of leads per month.
The lack of content, guides, industry white papers, etc. And once again, that's something I'd love to help remedy.
