.)- With that in mind, some ways to maximize that are:1) Use an automated follow-up/contact system for prospects and sphere, whether it's a monthly postcard, a hand-written note, an email newsletter, a print mailing - something.

They were targeting residential properties and the successful campaigns were using a postcard which directed the property owner to a website / landing page to enter a code (which told the investors what property was the subject of the response) and asked for a couple of other bits of info and then allowed the owner to schedule a time for someone to come see the property. 

The website would even send post cards for you.

Hi Lebert,Your best bet is to make some large postcards with your amazing shots on it with your website info then go to local realty offices and promote your business. 

I think I have heard that some direct mail services can insert the cash buyers name into the script you use on the postcard based off the list you send them.

My goal is to use a letter style mailing with hand written envelopes vs the printed postcard style which we already get far too many in the mail that immediately make it to the recycling bin.

Some say that get at least 1 letter or post card a week.

I thought about sending out postcards, reaching out to landlords, etc. and the only thing that ended up working was me being patient and me moving quickly. 

During a Mail campaign, how often do you mail out letters, post cards etc...?

Lists to consider are Absentee Owner with Equity, Seniors with Long-time Ownership and Owners with Low Financial Stability Scores (FSS)Sending letters or post cards will be more expensive than your current avenues, but you can talk to them about how easy you will make it for them to sell their house to you.
