How to send your letter
- 1
Check whether it can go through your online account first
Most servicers, including Sallie Mae, process forms faster through their online borrower portal than by mail. Use paper when a form needs a wet signature, you can't access the portal, or Sallie Mae has specifically asked you to mail something.
- 2
Include your loan/account number on everything
Write your full name and loan or account number on the form itself and on any cover letter — loose pages that fall out of an envelope are the most common reason mailed paperwork gets delayed or lost.
