GuessBox was made with the intention of providing the most seamless user experience, while giving you the end user full control over what they want to do with their lead data. GuessBox is also the only platform that combines both outbound email with lead generation and offers it as a package for an insanely affordable price!

On the one hand we gather data quite similarly to how other companies grab it - we use computer robots to go ahead and crawl the web to find publicly available information. However, that’s actually a small part of how GuessBox works.

GuessBox finds messy data from all over the web - names, locations, industry types, company names etc and then pieces it together to get a more or less a clear picture of who said person is. Once we have that our systems will go ahead and create / verify as many variations of that person’s information as possible until we hit a match.

This also means that you won’t be getting the same data that everybody else is using and/or has scraped from the web!

Absolutely! You can find all of our video demos and feature release videos on our YouTube channel. There is also a link on the far right of the navigation bar to our videos page.

We understand that we may not always have the data or specific leads you are looking for. If we don’t have a specific data set, a box will pop up after you search, asking you to submit your request directly to us.

Once we get your request, we’ll find you what you’re looking for free! *

As a general guide choose your leads as per the ‘How To Create The Perfect Outbound Email Campaign’ guide, and then use a top down approach. First type in the location of your lead, and hit search. See what kind of results you get back, note the down the ones that are relevant. Then you can start typing in industry | location to narrow them down.

Make sure you have an outbound strategy set up, and you have a couple of variations of email copy written to A/B test in your email campaigns.

These are just the basics of course, once you become a member we will periodically provide you with different resources and strategies to ensure you are getting the most out of using GuessBox. We also post a lot on our blog regarding strategies we found to work, email marketing innovations. In addition to this, make sure to check out our YouTube channel as we frequently upload video walkthroughs and demonstrations of different ways set up and optimize your outbound email campaigns.

We don’t offer a free trial because we don’t believe there should be a deadline of when you need to use the service by. That is why we offer free accounts with 50 lead credits pre-loaded. They never expire so feel free to use them whenever you please.

Free accounts have a limit on 50 leads that they can view/export. Once you have viewed 50 leads, the app will display the above message and ask you to upgrade to a paid account if you want to keep using it.
