Optimal Number of Contacts Over Six Months

[Earl White]

BiggerPockets Marketers,

I am conducting a direct mail campaign to targets over the course of six months for each target. I am planning to send several letters/postcards to each over the course of the six months.

Assuming money/time is not an issue, what is the optimal number of times to contact a lead over the course of six months? I want our brand/message on the targets mind as much as possible, but when does the quantity of advertisements become "annoying"?
