Our verdict
SimpleLogin suits people who want open-source email aliasing, a free plan and custom domains, and it runs from CH under Proton AG. The paid plan starts at $4, and the free plan limits let you test aliasing across real sign-ups before paying anything.

Pros and cons
Pros
- Open source code, with clients on Web, Chrome and Firefox so the same alias list works in a browser and on a phone.
- A usable free plan: the free plan limits give a set number of aliases, unlimited bandwidth and a single mailbox at no cost.
- Custom domains are supported, in line with the 86.1% of the secure email listings that offer them.
- Entry fees of $4 for the paid plan place it 13 of 37 brands on starting price, mid-field rather than at either extreme.
Cons
- The paid plan entry of $4 is higher than addy.io at $1 and Apple Hide My Email at $0.99.
- The free plan limits exclude custom domains, so putting aliases on a domain you own means moving to the paid plan at $4.
- End-to-end encryption is partial: PGP-encrypted forwarding with your own key is a Premium feature, and other mail is protected in transit only.
- Support runs on email, help centre and community only, with no phone line and no live chat.
Who it suits
- People signing up for newsletters and online accounts who would rather hand out an alias than their real inbox address, with a free plan that covers a set number of aliases.
- Readers who check who runs a service: the operator is Proton AG, based in Switzerland, and the code is open source.
- Subscribers who want aliases on a domain they own, since custom domains are supported on the paid plan.
Who should look elsewhere
- Apple Hide My Email users who want the lowest outlay, since it costs $0.99 against $4 for the SimpleLogin paid plan.
- Readers who want every forwarded message PGP-encrypted without a premium upgrade, since SimpleLogin limits that to Premium accounts.
- Anyone who needs chat or phone support, because SimpleLogin support runs on email, help centre and community.
Privacy and jurisdiction
SimpleLogin answers to CH law. The logging policy is where the privacy work shows most clearly: no permanent IP logs are kept, server logs are deleted after a short window, and emails are not stored, with only undeliverable messages held briefly. SMTP metadata is retained, and analytics run without cookies, which keeps tracking to what forwarding needs. End-to-end encryption is a qualified claim rather than a blanket one. Forwarded emails can be PGP-encrypted with your own key before they leave the server, but that option is Premium only. Everything else is protected in transit with TLS, so anyone expecting fully sealed mail should read that distinction before paying.
What it does well
Custom domains are the feature that lifts SimpleLogin above a disposable address generator, since aliases can sit on a domain you control and reply from the alias without exposing the real inbox. The free plan limits set the shape of the free tier: a set number of aliases, unlimited bandwidth, a single mailbox, and no custom domains. Unlimited bandwidth means forwarding volume is never the reason to move up, and a single mailbox keeps setup to a single forwarding address. The alias count is the practical ceiling, so readers who hand out a new address for every sign-up will reach it sooner than most.
Free plan and trial
A free plan is offered, and its limits are the whole story: a set number of aliases, unlimited bandwidth, a single mailbox, and no custom domains. Unlimited bandwidth means the volume of forwarded mail is not something to budget for, and the mailbox cap keeps setup to one inbox to forward into. For readers who only want to try aliasing across sign-ups and newsletters, the free plan limits are enough to start, and nothing here needs a card to be tested at real volume.
Who runs it
SimpleLogin is run by Proton AG, with the service based in Switzerland and the company dating its founding to 2,019 to 2,020. An operating company rather than an anonymous project means terms, jurisdiction and privacy policy all trace back to the same named entity, which is what auditors tend to look for first. Support runs on email, help centre and community, which is email, a help centre and a community forum. There is no phone line and no live chat, so readers who prefer a spoken answer will be relying on written replies.

Frequently asked questions
How much does SimpleLogin cost?+
The free plan costs nothing, and the paid plan starts at $4. That entry sits above Apple Hide My Email at $0.99 and addy.io at $1, so most readers start on the free tier. Custom domains arrive with the paid plan.
What does the free plan include?+
The free plan limits allow a set number of aliases, unlimited bandwidth and a single mailbox, and they exclude custom domains. Readers who reach the alias cap move to the paid plan at $4, where custom domains are supported.
Are forwarded emails end-to-end encrypted?+
Not for every message. Forwarded emails can be PGP-encrypted with your own key before they leave the server, and that option is Premium only, while other mail is protected in transit with TLS. The operator, Proton AG, states the default plainly: email in transit only.
What data does SimpleLogin keep?+
No permanent IP logs are kept, server logs are deleted after a short window, and emails are not stored, apart from undeliverable messages held briefly. SMTP metadata is retained, and analytics run without cookies. The service is operated from CH, so the logging policy and the law come from the same place.
Which company runs SimpleLogin and where is it based?+
SimpleLogin is run by Proton AG, with the service based in Switzerland and the company dating its founding to 2,019 to 2,020. Terms and jurisdiction sit in CH as well, so a reader checking who answers for the service finds one name.
Can I use my own custom domain?+
Yes, custom domains are supported, and that is the main reason to leave the free plan behind. The free plan limits allow a set number of aliases, unlimited bandwidth and a single mailbox, and they exclude custom domains, so a personal domain begins with the paid plan at $4.
Which browsers and apps can I use it on?+
SimpleLogin runs on Web, Chrome and Firefox, so aliases can be managed in a browser on desktop or on a phone. Clients cover the main desktop and mobile browsers. Support runs on email, help centre and community, which is written help rather than live chat.
How do I get help from SimpleLogin?+
Support runs on email, help centre and community: email, a help centre and a community forum. There is no phone line and no live chat, so questions that need a spoken answer are a poor fit, and anything urgent waits for a written reply.
How does the price compare with Apple Hide My Email and addy.io?+
The SimpleLogin paid plan starts at $4. Apple Hide My Email costs $0.99 and addy.io starts at $1, so both are cheaper at entry. The free plan limits and custom domains are what you trade that difference for.
