May not be right for some.
This is yet another theme that has been occurring as of late.
When starting a campaign, it is important to define what is a complete lead vs. what isn’t, otherwise the campaign is a waste of time, money and energy.
Instead of chasing down the incomplete information to make it complete, focus on the complete leads. After one gets through the complete leads, then during downtime, focus on putting the pieces together for the rest.
