Deceased Suppression
The Short Answer
Deceased suppression removes or flags records of people who are known to have died before a marketing or outreach list is used. Providers check the list against death records such as the Social Security Administration's Death Master File, obituary and probate data, and industry do-not-contact lists. It's a standard data hygiene step, because mail, calls and ads sent to someone who has died waste budget and can upset the family.
How It Works
Each record on the list is compared with one or more deceased sources. A record that matches is either removed or flagged so it can be reviewed before the list goes out. Because marketing lists rarely carry Social Security numbers, matching usually relies on name, address and, where available, date of birth. That makes the quality of the match rules as important as the size of the source.
Why It Matters
Continuing to contact a person who has died is wasted spend and a poor experience for their family, and it signals a list nobody has maintained. Records of deceased people are also a known target for identity fraud, so keeping them out of active audiences reduces risk as well as waste.
Where deceased data comes from
Social Security Death Master File (DMF). The best-known source, but not a complete one. Since 2011 the public version has excluded most deaths reported by states, so it misses a large share of recent deaths. Since 2014, access to deaths from the last three years is limited to users certified under the Limited Access Death Master File program run by NTIS.
Obituaries and probate records. Commercial providers compile published obituaries and court records to cover deaths the DMF misses. Coverage varies by provider and region.
Do-not-contact lists. The ANA (formerly the DMA) runs a Deceased Do Not Contact list through DMAchoice, where family members can register a relative who has died to reduce marketing mail.
How often to run it
Deaths happen every day, so a list that was clean last quarter isn't clean today. Treat deceased suppression as part of every pre-campaign hygiene pass rather than a one-time cleanup, alongside deduplication and contact verification. The longer a list sits unused, the more it matters.
Flag before you delete when the match is weak. A name and city match on a common name can catch the wrong person, so review low-confidence matches instead of dropping them automatically.
Deceased suppression in Exact Match
Exact Match's Clean ID product flags and suppresses records that match deceased databases as part of list cleaning, so the same pass that verifies and enriches a list also removes people who have died. Deceased suppression only covers deaths. It doesn't replace your own opt-out and do-not-contact suppression, which stays with you under Exact Match's Acceptable Use Policy.
Frequently Asked Questions
What is deceased suppression?
Deceased suppression is the process of removing or flagging records of people who have died before a list is used for marketing or outreach. Records are matched against death records such as the Social Security Death Master File, obituary and probate data, and industry do-not-contact lists.
Is the Death Master File enough on its own?
Usually not. Since 2011 the public Death Master File has excluded most state-reported deaths, so it misses many recent deaths. Providers fill the gap with obituary, probate and other commercial sources. Access to deaths from the last three years also requires certification under the Limited Access Death Master File program.
How often should I run deceased suppression?
Before every campaign. Deaths happen continuously, so a list cleaned months ago will have new matches today. Build it into the same pre-send hygiene pass as deduplication and contact verification.
Does deceased suppression replace opt-out suppression?
No. Deceased suppression removes people who have died. Opt-out, do-not-contact and do-not-sell-or-share suppression are separate obligations that you still need to honor in every system that holds the data.
