Email alias services create disposable or semi-permanent forwarding addresses that hide your real inbox from shops, apps and newsletters. As of April 2026, the four mainstream options most people will actually use are SimpleLogin, Apple Hide My Email, Fastmail Masked Email and DuckDuckGo Email Protection, and they differ sharply on alias limits, custom domains, reply support and app integration. The short version: SimpleLogin is the most flexible; Apple Hide My Email is the easiest if you already pay for iCloud+; Fastmail works best if you want aliases tied to your own mail hosting; DuckDuckGo is the simplest free option, but it is the weakest for power users and for avoiding re-identification by determined senders.
What each service actually offers
As of April 2026, SimpleLogin is owned by Proton and works as an alias-forwarding service with browser extensions, mobile apps and custom-domain support. It offers random aliases, directory aliases and reverse-alias reply support so you can answer a message without exposing your real address. As reported by Proton in 2022, SimpleLogin joined Proton after the acquisition, and it continues to run as a distinct product.
As of April 2026, Apple Hide My Email is included with iCloud+ and generates random relay addresses tied to your Apple account. It is tightly integrated into Safari, iOS and macOS sign-up flows, but it does not expose the same level of mailbox-like control or broad cross-platform tooling as SimpleLogin or Fastmail. A practical example: if you sign up to three shopping sites on an iPhone, Apple can create three different aliases in seconds, but managing them later from a Windows laptop is much less convenient.
As of April 2026, Fastmail Masked Email is built into Fastmail and also integrates with 1Password so you can create a masked address during account creation. That makes it unusually good for people who already use 1Password and want aliases attached to a full paid email account rather than a forwarding-only layer.
As of April 2026, DuckDuckGo Email Protection gives users a free @duck.com address and private aliases that strip many email trackers before forwarding mail to your real inbox. It is easy to start and costs nothing, but its feature set remains lighter. If you need custom domains or advanced reply workflows, it is not the strongest option.
Pricing, limits and where the ceilings are
Price matters less than limit design. A service with a low monthly price but a hard cap of 100 aliases can be worse than a service included in something you already pay for.
As of April 2026, Apple Hide My Email is bundled into iCloud+, which starts at a low monthly price in most regions, but you only get value if you already want Apple storage and services. It is cheap on paper, yet its lock-in is real: the best experience is on Apple devices.
As of April 2026, DuckDuckGo Email Protection is free. That makes it the lowest-friction choice for someone who wants aliases for five to 20 websites and does not care about custom domains. The trade-off is control.
As of April 2026, Fastmail Masked Email is included with a Fastmail subscription, so the effective price is the price of your email provider, not just aliasing. If you were going to pay for hosted email anyway, this can be efficient. If you only want aliases, it is expensive.
As of April 2026, SimpleLogin has a free tier and paid tiers, with the paid plan aimed at people who need larger alias counts, custom domains and more administration features. In practice, SimpleLogin is the easiest recommendation for someone managing 50 to 500 aliases over several years because it was built around that use case.
A useful scenario: say you create one alias for every account you open in a year. At 8 sign-ups a month, you hit 96 aliases after 12 months. That is enough to expose the difference between a generous system and a toy one.
Custom domains and sending from an alias
This is where the services split cleanly.
As of April 2026, SimpleLogin supports custom domains and subdomains, which lets you create aliases like [email protected] or [email protected]. It also supports replying from aliases through reverse aliasing. For anyone who wants portability, this matters: if you later switch providers, you can keep the domain and update routing instead of changing hundreds of sign-ins.
As of April 2026, Fastmail also supports custom domains because it is a full email host, and its Masked Email feature can fit neatly into that setup. If you run your own domain for personal email, Fastmail is more coherent than Apple or DuckDuckGo. The comparison is straightforward: SimpleLogin gives you a stronger dedicated alias layer; Fastmail gives you aliases plus the inbox itself.
As of April 2026, Apple Hide My Email does not give users a custom-domain alias system in the same sense. It is designed around Apple-managed relay addresses. That is fine for quick sign-ups, but weak for long-term portability.
As of April 2026, DuckDuckGo Email Protection also does not compete as a custom-domain platform. It is a forwarding and tracker-stripping tool first.
If you need to send from the alias, not just receive, SimpleLogin is the strongest of the four. Fastmail can also handle sending workflows well because it is a full mail provider. Apple and DuckDuckGo are much more limited here.
iPhone, Android and browser autofill
Alias tools live or die on speed. If creating an alias takes 30 seconds, many people stop using it.
As of April 2026, Apple Hide My Email has the best native iPhone experience. In Safari and Apple account flows, it is effectively one tap. On an iPhone-only setup, Apple beats every rival on convenience.
As of April 2026, Fastmail Masked Email has one of the best cross-service workflows because of its 1Password integration. If you create a new login in 1Password, you can often generate a masked address at the same time. For a person creating 10 new accounts in an afternoon, that is materially faster than copying addresses between apps.
As of April 2026, SimpleLogin offers browser extensions and mobile apps on iOS and Android, with practical alias creation across platforms. It is not as deeply embedded into iOS as Apple’s own system, but it is far better if you move between Android, Linux, Windows and iPhone.
As of April 2026, DuckDuckGo Email Protection works well enough for browser-based sign-ups, especially if you already use DuckDuckGo’s tools, but it is less integrated than Apple on iOS and less powerful than Fastmail plus 1Password or SimpleLogin’s dedicated setup.
The practical ranking is simple:
- Best on iPhone only: Apple Hide My Email
- Best cross-platform for heavy alias use: SimpleLogin
- Best if you already live in 1Password and paid email: Fastmail
- Best free starter option: DuckDuckGo
Which one best prevents newsletter re-identification?
Alias services stop direct reuse of your real email address, but they do not magically stop all re-identification. A newsletter can still correlate you by IP address, link parameters, purchase history, referral codes, device fingerprinting or the fact that you click the same personalised links from the same browser.
As of April 2026, the best defence against newsletter re-identification is not one specific alias brand. It is using a unique alias per sender, turning off remote content where possible, and cleaning tracking parameters from links before sharing or archiving them. If you care about share-link hygiene, use https://tool.notrackr.com/ to strip common URL tracking parameters.
SimpleLogin and Fastmail are strongest here because they make one-alias-per-newsletter habits sustainable at scale. Apple Hide My Email is good for casual use, but power users often end up with less organised alias inventories. DuckDuckGo adds tracker removal in emails, which is useful, but tracker stripping alone does not defeat a sender that embeds account IDs in links. A concrete example: if Newsletter A sends to alias-one@example and Newsletter B sends to alias-two@example, but both links contain subscriber_id=847392, the sender can still tie actions back to the same profile.
If your goal is to identify which company leaked or sold your address, all four help if you use one alias per service. If your goal is to stop all cross-context profiling, none is enough on its own.
Privacy, ownership and what to choose
Ownership and architecture matter because alias providers necessarily handle message routing.
As of April 2026, SimpleLogin is Proton-owned. Proton is based in Switzerland, and SimpleLogin’s public positioning is strongly privacy-focused. As reported by SimpleLogin and Proton in public security pages and blog posts, the service has undergone external security review, but readers should still distinguish between an app security audit and a broad proof of non-retention. Alias providers process metadata by design.
As of April 2026, Apple is a US company and Hide My Email is part of the iCloud ecosystem. That means convenience is excellent, but the jurisdiction is the US and the system is tied to your Apple account. For readers thinking about Schrems II implications, Apple-hosted relay infrastructure and account data remain part of a US-headquartered platform even if some processing is regional.
As of April 2026, Fastmail is owned by Fastmail Pty Ltd and is based in Australia. It is a paid email provider with a long-standing independent reputation, but Australia is still a Five Eyes jurisdiction. For some readers that is acceptable; for others it is a deciding factor.
As of April 2026, DuckDuckGo is a US company. Its Email Protection product is privacy-improving compared with giving every merchant your main address, but it is still a US-based forwarding layer.
My practical picks:
- Choose SimpleLogin if you want the best dedicated alias service in 2026, especially for custom domains, reply support and managing dozens or hundreds of aliases.
- Choose Apple Hide My Email if you use iPhone, Safari and iCloud+ already, and you mainly want frictionless aliases for shopping, apps and one-off sign-ups.
- Choose Fastmail Masked Email if you already pay for Fastmail or want aliases tightly integrated with 1Password and a full hosted mailbox.
- Choose DuckDuckGo Email Protection if you want a free starting point and basic tracker stripping, and you do not need advanced control.
What to do next: list the next 20 accounts you create this year and decide whether you want convenience, portability or scale. If you want the least regret later, start with one unique alias per account and keep a simple record of which alias goes where. That habit matters more than brand choice.
