Honestly, Sam, could you have thought of a more specific, descriptive subject line??
Pull out some basic marketing tactic b.s.: segment your potential customers based on certain criteria that might be a strong indicating vector... e.g., do they have school-aged children, are they geographically in the area, are they recent parents with a longer sales lead time that might require more drip marketing, etc.?
Then for each segment, identify key messages that will motivate each one uniquely, addressing their specific needs and concerns.
Consider different media to reach them: online display ads, email, printed postal mail fliers, local events and sponsorships, etc.
Lather, rinse, repeat -- especially if you're tracking all this stuff in a CRM and can view which segmentation-based campaigns are taking off and which ones are not. Double down on the ones that are effective and pull back on those that haven't been.
How's that for starters?
