With mprospeotor I can run any reports (including custom ones) directly into Salesforce via REST API so we get instant BI feedback when our outbound activity comes up for debate. It gives us an extra level of confidence since everything has been put together around me. Nothing! As mentioned above this tool integrates well but it's not always as intuitive nor reliable than one that looks like something more you'd be accustomed too. In particular there are some UI issues where sometimes some filters show or hide things. So if those dont fit whatyou're usedto - take time exploring it till they do! We've really benefitted using these tools especially now days, that every marketer needs access tot he same pool of information across their organisation whether inside marketing orgs / external agencies. It’s easy to use and great for any sales team member. If you're able to get it set up correctly it does exactly what it says on the tin - finds prospects within a defined area. The only downside really is that there are some limitations around how many people can be using the system at the same time. We are finding it useful for our sales teams in being able to find new prospects quickly and easily.
