Simple question about probate marketing

[Kyle McCorkel]

I've been marketing to probates for the past 6 months with limited success.  Recently I've begun revamping my marketing and will be using a direct mail service to send out multiple monthly mailings (for 6 to 12 months) to each lead.

The direct mail service has a 200 piece minimum.  Each week I get about 25 new leads.

So my simple question is this: how important is it to mail the executors IMMEDIATELY after they form the estate with the county? If I want to use the direct mail service, I'd have to wait about 8 weeks to send out a new batch.  Should I be concerned about timing for the 6, 7, 8 week old leads? I feel like many of them could have sold or listed in that time.

Any suggestions?
