Almost all sweepstakes do offer an alternative mail-in entry (see "Rules" for details), but we only list those here that offer mail-in entry as the only entry method.
Make your mail-in entry stand out by using a colored and/or odd-shaped envelope for your entry. Ask the card stocker at your discount store if they have any envelopes they plan to throw away. The best days to catch them is the day after a Holiday. I have gotten several hundreds of cool envelopes this way! ~Kim
