Our verdict
Fastmail Masked Email suits people who want disposable addresses inside a long-running paid email account, not a standalone privacy service. Founded 1999 and starting at €4, it pays off if you already want the wider mail suite, though the free plan is not offered.

Pros and cons
Pros
- Founded 1999, with apps listed for Web, iOS and Android.
- Custom domains are supported, so masked addresses can sit on a domain you already own.
- Personal data is not sold, customer data is not used for AI training, and IP logs are kept for fraud monitoring.
- Terms sit with Fastmail Pty Ltd under AU law, so the contracting party is named.
Cons
- Data is encrypted in transit and at rest on Fastmail servers, and end-to-end encryption reaches Fastmail mail only through third-party apps using PGP or S/MIME.
- The free plan is not offered, and No free plan; 30-day free trial covers a trial rather than ongoing free use.
- Support runs on email and help centre only.
Who it suits
- People who already pay for Fastmail and want throwaway addresses for sign-ups.
- Readers who want the legal entity named up front: Fastmail Pty Ltd under AU law.
- Users on Web, iOS and Android who want masks handled inside the mail app.
Who should look elsewhere
- Not for shoppers weighing only the entry price: addy.io starts at $1 and Apple Hide My Email at $0.99, while Fastmail starts at €4.
- Not for anyone who needs end-to-end encryption inside the provider's own apps, because end-to-end encryption is not offered there and PGP or S/MIME needs third-party apps.
- Not for people who want a permanent free tier: the free plan is not offered, and No free plan; 30-day free trial covers a trial rather than ongoing free use.

Frequently asked questions
How much does Fastmail Masked Email cost at the start?+
Plans start at €4, which is the entry price to compare here. On starting price it ranks 15 of 37 brands, while the median starting price across secure email sits at €4.38.
Is there a free plan?+
The free plan is not offered, and No free plan; 30-day free trial sets out the no-cost route, which is a trial. Free plans are common in this category, 78%, so masked addresses here always sit behind a payment.
Is Fastmail email end-to-end encrypted?+
End-to-end encryption is not offered in Fastmail's own apps. Data is encrypted in transit and at rest on Fastmail servers, and PGP or S/MIME works only through third-party apps. Readers who need end-to-end encryption inside the app should weigh that before subscribing.
Which apps and devices can I use?+
Fastmail's apps cover Web, iOS and Android, so masks can be managed wherever you read mail. The service sits in the budget tier on price, and the entry price is €4. Masked addresses sit inside the Fastmail subscription rather than a separate product.
Who runs the service and which law applies?+
Terms are with Fastmail Pty Ltd, headquartered in Australia with jurisdiction in Australia. The company reports being founded 1999, and it is not open source, so the code behind the service is not published for inspection.
What happens to my data and how do I get help?+
IP logs are retained for fraud monitoring, personal data is not sold, and customer data is not used for AI training. Support runs on email and help centre, so help comes by email or the help centre rather than by phone.
Can I use my own domain for masked addresses?+
Custom domains are supported, so masked addresses can sit on a domain you already own. That puts this brand with the majority in secure email, since 13.9% of the brands compared do not offer custom domains.
What will it cost once the trial ends?+
The trial is the introductory part, No free plan; 30-day free trial. After it, ongoing pricing starts at €4, and longer-term plans across this comparison run at a median €3.97, so renewal is where the real cost shows up.
