Removal tries to delete information that has already escaped. Prevention controls what you hand over next. They address different halves of the problem and neither replaces the other. If your name and home address are published on people-search sites, that's a removal problem and no alias will help. If companies you sign up with keep leaking your email, that's a prevention problem and removal barely touches it, because your next signup recreates it.
The two mechanisms
| Removal | Prevention | |
|---|---|---|
| What it acts on | Records third parties already hold | What you disclose from now on |
| Who has to cooperate | The broker, or a regulator compelling them | Nobody |
| How long it takes | Weeks, and repeats indefinitely | Immediate |
| Covers your past exposure | Yes, partially | No |
| Covers future exposure | No — new records keep appearing | Yes |
| Typical cost | A recurring subscription, or free via a statutory route | Free to a few dollars a year |
| Ends when | It doesn't; brokers re-acquire | You stop using it |
What removal is genuinely good at
Removal is the only option for data that is already published, and for data types an alias can't touch. If a people-search site lists your home address, your age, your relatives and your phone number, that is a real harm with real consequences — harassment, stalking, social-engineering attacks on your accounts — and the only fix is getting it taken down.
Nothing on the prevention side addresses that. An email alias created today has no effect on a property record from 2019.
Its structural limitation
Removal is a treadmill by design. Brokers continuously re-ingest from public records, commercial sources and each other, so a record deleted this month can reappear next quarter from a source you never dealt with. That's why removal services operate as recurring subscriptions rather than one-off jobs — Incogni's own site describes repeated waves of requests roughly 10 days apart. Source: incogni.com. Checked: 2026-08-19.
This isn't a criticism of any particular service. It's the shape of the problem: you're trying to empty a bath while the tap runs.
What prevention is genuinely good at
Prevention closes the tap, at least for the stream you control. Give each company a different email address and three things follow: a breach at one company exposes an address nobody else holds, spam identifies its own source, and you can revoke any single company's route to you without asking them.
The key property is unilateral control. Every removal request depends on someone else acting. Disabling an alias depends on nobody.
Its structural limitation
Prevention is prospective only. It does nothing about the fifteen years of signups already behind you, and nothing at all about non-email data. If your phone number is already in circulation, aliases are irrelevant to that.
Working out which you need
| Symptom | Problem | What helps |
|---|---|---|
| Your details show up on people-search sites | Removal | DROP if you're in California; otherwise a removal service or manual opt-outs |
| Spam volume climbing, mostly generic | Prevention | Per-service addresses; filtering |
| Cold calls and physical junk mail | Removal | Removal, plus the relevant opt-out registers |
| You want to know who leaked you | Prevention | Only per-service addresses can answer this |
| Post-breach anxiety about one company | Both | Prevention going forward; removal for what's circulating |
| Setting up a new identity for a new job or move | Prevention | Start clean; every service gets its own address |
The free route people miss
If removal is what you need and you live in California, the state runs a free deletion platform. One verified request through DROP reaches every registered data broker, and since 1 August 2026 those brokers have been required to check it at least every 45 days and process what they find. Source: CPPA. Checked: 2026-08-19.
It won't cover unregistered brokers or non-California residents, and it's newer than the commercial services, so it isn't automatically the better choice. But it is free, and it is worth trying before paying a subscription. How DROP works.
Where the marketing gets misleading — in both directions
Removal services sometimes imply that deletion makes you unfindable. It doesn't. It reduces your presence on the brokers covered, for as long as the service keeps working, and says nothing about the next dataset.
Alias services — including this one — can equally overreach by implying that prevention makes removal unnecessary. It doesn't. If your address is on a people-search site today, no alias changes that.
Anyone telling you that one of these replaces the other is describing their product line rather than your problem.
Where Don't SPAM Me sits
Firmly on the prevention side, and only there. We don't file removal requests, we can't delete anything from a broker, and we're not a substitute for a removal service if published personal records are your problem.
What we do is the address half: unlimited aliases on a domain you own, created automatically on first use, with spam attributed to whichever company leaked the address, and one-tap disabling that hard-bounces the sender.
The straight comparison with a removal service is in Don't SPAM Me vs Incogni, and the options if you've decided removal is what you need are in Incogni alternatives.
