What the Response Numbers Actually Say
Start with how mail response is defined. Postalytics, in its roundup of direct mail statistics, gives the formula plainly: responses divided by pieces sent. A response can be a phone call, a scan, a visit, or a reply card, and none of those is a deal. Across the industry figures it compiles, response to a mail piece lands at a few percent of recipients, so most owners who open the mailbox do nothing about your letter. A distressed-owner list is a cold list from the sender’s side, which means planning around the modest end of that range.
Calls have their own reality check. In the Baylor Keller Center’s study, agents placed 6,264 cold calls in 2011 and 28% reached someone. They set 19 appointments, about 0.3% of dials, or roughly one appointment for every 330 calls. Those agents were prospecting for listings, not buying distressed houses, and a targeted list should do better than their numbers, though by how much is something only your own data can say. It remains the only cold-calling benchmark with a disclosed method that we are comfortable citing, so treat it as a floor to improve on, not a forecast.
Why the Two Channels Cover Each Other’s Failures
Mail fails by being ignored. Calls fail by not connecting. Because the failures differ, each channel patches some of the other’s. A letter reaches the property even when the phone number is wrong, rolls to voicemail, or belongs to someone who screens everything. It also gives an owner time to think privately about an offer they may not be ready to discuss out loud. A call reaches a person in real time, answers questions a letter cannot, and can turn a half-formed maybe into an appointment, but only when somebody picks up.
There is probably a familiarity effect on top of that, though we have not seen anyone measure it for this niche. A caller who follows a letter arrives as a follow-up instead of an interruption, and an owner who has seen the name before may stay on the line longer. Test it on your own lists before you count on it. The comparison of cold calls and cash-offer letters as a first touch covers the either-or version of this debate, and the point here is that you rarely have to choose.

Book a Real Estate Fit CallA Sequence That Works on One List
Build one master list with a single ID per owner, so mail records, call records, and responses all attach to the same person. Suppress anyone with a prior opt-out, anyone already in a live conversation, and any number you cannot legally call. Drop the first mail piece to the whole list, then start calls on the owners with callable numbers once the piece has had time to arrive, spreading attempts across different days and times. Send a second piece to owners who have not responded, and stop contacting anyone who asks you to stop.
Keep the message consistent across channels. The letter’s offer language and the caller’s opening should sound like the same company, and the caller should not assume the letter was read. A line like “you may have seen a note from us about the house” works whether or not it landed. Give each mail drop its own tracking phone number or code, so inbound calls get tagged to the right drop and your callers do not cold-dial someone who already phoned you back. The deal-source attribution guide covers the setup.
Spend Mail on Signal and Dials on Breadth
Mail carries a per-piece cost for printing and postage that a dial does not, so it rewards focus. Send it to the segments with the strongest stack of signals, such as absentee ownership, long tenure, tax delinquency, or code violations, and let calls cover the wider list. The list stacking guide explains how to build those segments. A cheap, thin mailer to a whole county spends money where the signal is weakest.
Mail also plays a compliance role, with a limit. A letter is not governed by the phone rules, so it is a legitimate way to reach an owner whose number is on a registry. But a letter is not consent to call, and an owner who asks to stop hearing from you has opted out of the whole sequence, mail included. Foreclosure-related mail can also fall under state rules for solicitations to owners in default, so check the wording against your state before the first drop.
Measure Your Own Numbers
Borrowed benchmarks only get you to the starting line. Split one list at random into three groups: mail only, calls only, and mail then calls. Run them over the same weeks and compare appointments and qualified leads per owner contacted and per dollar spent. A single drop on a small list will be noisy, so repeat the test across several drops before changing the plan. You are looking for the mix with the lowest cost per qualified conversation, not the highest response rate.
If the calling half is where your hours run out, that is the half VA Horizon takes over. Its managed cold calling puts trained callers on your list after the mail lands, and you pay per qualified lead, not per hour of dialing.
