Frequently Asked Questions
How does the Email Privacy Checker work?
Our tool analyzes your email provider's privacy practices including encryption standards, data handling policies, breach history, tracking behavior, transparency, and legal jurisdiction. We cross-reference this against our database of known email provider policies to generate a comprehensive privacy score.
Is my email address stored when I use this tool?
No. We do not store, log, or transmit your email address to any server. The analysis runs entirely in your browser using our pre-compiled privacy intelligence database. Your email never leaves your device.
What does the privacy score mean?
The privacy score (0-100) reflects how well your email provider protects your privacy across 6 categories: encryption, data handling, breach history, tracking, transparency, and jurisdiction. Scores above 70 are good, 40-70 need improvement, and below 40 indicate serious privacy risks.
How can I improve my email privacy score?
The most impactful change is switching to a privacy-focused provider like ProtonMail or Tutanota. For day-to-day signups, use temporary email addresses from Temp Postal to avoid exposing your real email. Enable two-factor authentication and use unique passwords for every service.

How private is your email address?

- Explains what each score means rather than showing a bare number.
- No account, no storage, no follow-up email.
- Recommends the specific change that improves the weakest dimension.
Why an email address is an identifier, not just a mailbox
An address is the join key of the modern data economy. Two companies with no relationship can each hold a record about you, and because both records contain the same address, a broker can merge them into one profile. Nothing else you routinely hand over works so reliably across so many contexts.
That is why an address built from your real name is worse than a random one even though both deliver mail identically. The mail function is unchanged; the linking function is what leaks.
What each dimension measures
Identifiability looks at whether the local part contains your name, initials, birth year or other personal data. firstname.lastname is the worst common pattern because it identifies you even to someone who has no other information.
Domain exposure looks at what the domain reveals. A company domain tells a recipient where you work. A regional provider narrows your location. A large consumer provider reveals little in itself, which is why it is the least bad of the common options.
Guessability measures how easily an address can be produced without ever having been given it. Predictable formats are enumerated at scale, which is how addresses that have never been shared still end up receiving spam.
Circulation estimates how likely the address is already to be in marketing and breach datasets, based on its age, its format and its exposure profile.
Turning a poor score into a better one
You usually cannot fix a primary address that is already circulating. Its value to a broker comes from history, and that history exists. What you can do is stop adding to it: keep the existing address for the small set of accounts that genuinely need continuity, and stop using it anywhere else.
For everything else, use an address that expires. Newsletters, one-off downloads, trials, forum accounts and marketplace signups do not need an identifier that lasts a decade, and giving them one is what builds the profile in the first place.
Where disposable addresses fit and where they do not
A disposable address is right when losing access costs nothing: a download, a trial, a signup you are evaluating. It is wrong for banking, government services, employment and anything with recovery implications, because you will need that mailbox in six months.
Sorting signups into those two categories, rather than trying to protect one address forever, is the change that actually reduces exposure.
Frequently asked questions
Does the checker send my address anywhere?
The analysis is a scoring exercise on the address itself. Nothing is stored, and there is no account to attach a result to.
Why does my work address score badly?
Because it identifies both you and your employer, and it usually follows a predictable pattern that can be generated for every colleague. That combination is the most exposing of the common formats.
Are plus addresses a good fix?
They help organise mail but not privacy. The base address is trivially recoverable by stripping the tag, and many senders strip it before storing.
Is a random address at a major provider private?
More private than a named one, since it does not identify you directly. It still becomes a persistent identifier once shared widely, which is the underlying problem.
Should I abandon my main address?
No. Keep it for the accounts that need continuity and stop expanding its footprint. Retiring a well-used address usually creates more risk than it removes.
