I do some code violations, unlawful detainers and probate marketing however the list size is small  I’m also spending 15,000 a month on TV in my market that gets me 49% reach and a 12 frequency PPC YouTube and Facebook I am enjoying as well. 

Frequency is difficult to say as each marketer may have a different approach or run separate mailing campaigns.

This site has now surpassed Facebook when it comes to my frequency of use.. it's the next big thing :)

Hey @Jon Klaus - we hit different groups at different frequencies, something like:Absentees - MonthlyOwner Occ - Every 6 to 8 weeksProbate - Hit them twice in 30 days then every 2 months for about 9 months maxWe don't stop mailing once we have our frequencies tuned in - but we do refresh each list every 6 months to get the news and drop the outdated records....

I haven't looked into anything like this and don't know what to expect it terms of cost, I just know that the spreadsheet I've been using (which is not too sophisticated, but not basic either) is not one that can be used if I wanted to ramp up the quantity and frequency of my mailings and manage/keep track of incoming calls. 

So, frequency of mailing should be of high importance to you as a direct mailer.

Direct mail is a game of frequency and building a psychological AWARENESS of you and TRUST that you could solve their problem.

@michealquarles does your company set the frequency of the mailings?

I cannot purport to gauge the decibel level of frequency of the alleged barking/partying.

Definitely, so long as the amount and frequency is court-ordered and there is proof that it is/has been paid.
