SMS keeps beating mail on cost per contract in this comparison, and that looks too good
Building a channel comparison for an acquisitions budget, and the SMS column looks too good, which usually means something has been left out. Mail: 10,000 pieces at $0.62 all in, so $6,200. Response 0.9 percent, 90 calls in. Say 14 percent of those become a real conversation with a seller who will talk price, so 12 or 13. Contract rate 1 in 8. Call it 1.6 contracts, roughly $3,900 a contract. SMS via a vendor: 10,000 records skip traced at $0.09, so $900. Vendor charges $0.035 a message plus a platform fee, with a historical average of 2.8 messages per record before they stop, so about $980 plus $600 platform. Total roughly $2,480. Reported response is 6 percent, 600 responses, but 70 percent of those are wrong number or hostile, leaving 180 usable. A reported contract rate of 1 in 22 gives 8 contracts and $310 a contract. That spread is a factor of twelve, and nothing in real estate holds a factor of twelve for long. The likely leaks: carrier filtering means delivered volume is well under sent volume while quotes are usually given on sent, the 1 in 22 figure tends to be a vendor's best client rather than a median, and the labor to work 180 usable responses inside an hour of arrival rarely appears in either column. Texting consent and outbound rules are also the live regulatory question in this channel, and any adverse change hits the SMS column and not the mail column. The decision this framework should settle is whether a 90 day SMS test at $7,500 is worth funding against a mail program whose numbers are already known.
