Why spend tens of thousands of dollars on a marketing automation tool when Lookup Helper in addition to a few other applications (like Rollup Helper and MailChimp) can do the same thing for a quarter of the price?

With Lookup Helper you will be able to directly link your leads/contacts to a campaign. You may then use Rollup Helper to aggregate valuable information to the campaign record, and Mailchimp to send campaign specific emails to those leads/contacts.
