If you send letters once a week, odds are someone will remove it, or want you to stop mailing it and remove it.

 

Type up the letters once, save them on your PC. If you want to save time, print out say 5 at a time, place them in an envelope. Each week, stamp and mail it out. I would send one every 2 weeks though, since I think that is how long it takes to get approved/rejected?
