Is direct mail still effective for reaching auction buyers?

It can be, especially for certain audiences. Postcards and printed brochures still work well for real estate auctions, farm and equipment sales, and high-end collections where you want a piece people can hold, keep, and pass along. Older buyers and people in rural areas may respond to mail more than to email.

The key is a good list. Mailing to your own past bidders and consignors usually beats mailing to a broad purchased list. For real estate, some companies mail to nearby property owners, investors, or people in related trades. Ask a local mailing service about bulk rates and list options in your area.

Keep the piece clear: a strong photo, the sale name, dates, location or website, and how to bid. Because mail costs more per person than email, track results by asking bidders how they heard about the sale, and focus mail on the sales where it pays off.
