I'm paranoid (unfairly) and to reals of "tenant stuffing".

Chris- depends on the time you have allotted for this and how you could otherwise be spending the time printing and stuffing.

Letters for me = .11 cents envelope .10 Letters .44 Stamp = .65 (aprox) per letter+a lot of time stuffing and stamping them.Over 2,500 mailers that's $800 for postcards$1625 for lettersI would bet you would get a better response rate mailing postcards twice then mailing a letter once.

They'll take out walls, stairwells etc. stuffing their oversized (hand me down) couches up your walls.

In addition you should check if the tub's overflow is indeed working (could have been clogged up by some kid having stuffed something down the holes or whatever, one never knows).

The class ran from 9-6 and was stuffed with information. 

You will get between a 5 - 25% response (5-25 responses for every 100 letters you send out).MY ADVICE: Learn (and love) to process data and you will make millions in real estate.There are 26,387,452+ tax defaulted properties in the US at the moment.If you are using unrelated third parties to send out mailers at any step of the way(except printing & stuffing), you are kicking the can down the road.  

Hello people of BiggerPockets,I am just getting started and have a few questions regarding direct mail, so for all the experienced people out there I'd love to hear your opinions.I am looking to outsource my direct mail because it is taking a long time to hand write envelopes that are being stuffed with sub-par printed out letters.

BTW, Folding, stuffing, and putting the stamps on are the hardest part.

Looks good to me, but I just got done printing my first batch of letters from ListSource - 896 of them - which wasn't that bad, but we'll see how stuffing them goes though.I had last sale date at 1/1/1998 for a solid 15 years of ownership.
