Post Cards vs. Letters for Lead Gen

[Sean Wilt]

Hello,

Curious to get opinions on effectiveness of using postcards vs. hand signed and addressed letters for marketing.  I get the the post card route is way more efficient from a time perspective (although at twice the cost), but really wondering about response rates.   I feel like I get laminated post cards from multiple sources/industries almost every day and I just toss them without more than a glance. While a hand written addressed letter, I feel would get my attention a bit more.

I won't be doing thousands of reachouts initially, just 250 or so per month so while letters would be more time intensive, I am open to it if the response rate is better.
