Frequently asked questions
The current limit is 25MB. For large attachments, we suggest using a file upload service and send the link instead. You can find some file sharing services that respect our privacy on PrivacyTools
Another reason of having this limit is the PGP encryption is a heavy process, supporting a bigger size can put a big load on our server.
10MB is also the default size limit used in Postfix, a popular email MTA that SimpleLogin is using.
When an alias is deleted, it's put into a global trash and we make sure that it can't be reused. All historic information on the alias (the account that creates the alias, alias contacts, etc) are deleted to respect your privacy.
This applies to all aliases created with SimpleLogin domains.
You can however restore an alias created with your own domain.
Our PGP key for email@example.com can be downloaded here (fingerprint "BB03 4466 7D70 C5EC 30B5 A07C 704B 2826 4E7C A9E6"). It's also available on keys.openpgp.org
If you enable PGP, all emails are signed with firstname.lastname@example.org key which can be downloaded here (fingerprint "7961 6C8F 8E0A 05D1 340F FC20 4749 AAC8 4D4C 4810"). It's also available on keys.openpgp.org
At the bottom of the Settings page, you can delete your account. This operation is irreversible and we have no way to recover your data.
The short answer is yes you can. We use email aliases to run our business, manage our taxes, handle our bank operations and so far so good :).
A longer answer is the email protocol is designed to be highly resilient and an email is almost never lost. If SimpleLogin cannot deliver the email to your mailbox, we will notify you so you can take appropriate action. You can also set up a secondary mailbox in addition to your primary mailbox that can be used as a backup.
Email alias is similar to forward email address: all emails sent to an alias will be forwarded to your inbox.
Thanks to SimpleLogin technology, you can also send emails from an alias.
For your contact, the alias is therefore your email address.
Email subaddressing, also known as the plus (+) trick, is popularized by Gmail and supported by some email services, allows you to create new email addresses by appending "+" to your current email address. Says your email is email@example.com, you can quickly create another address like firstname.lastname@example.org for Facebook, email@example.com for Groupon, etc.
Though practical, it has some downsides:
- You cannot reply from the + address: your real email will appear as the sender.
- The + trick is well-known and some websites don't allow sign-ups with email addresses that contain +.
- Using + trick doesn't protect your privacy: one can easily remove the + part to have your real email. If your + address appears in the data breach, your real address is probably also in the hands of spammers. You could check whether your email is leaked using website like have i been pwned
- By removing the + part, advertisers can link these + addresses together to have your browsing history.
SimpleLogin aliases don't have any of these downsides.
In addition SimpleLogin could also help manage your business emails. If you own a domain and don't want to pay a full solution like GSuite, you could add the domain into SimpleLogin and create emails like firstname.lastname@example.org, email@example.com with aliases. All our business emails (the @simplelogin.io) are actually aliases.
SimpleLogin is the most advanced email alias solution and is in active development. Here are some differences between SimpleLogin and other email forwarding/alias services:
- Fully open-source: both SimpleLogin server and client code (browser extension, JS library, mobile apps) are open-source so anyone can freely inspect and improve the code.
- Covers all major platforms: Chrome/Firefox/Safari extension for desktop, iOS and Android apps for mobile.
- The only email forwarding solution that can be self-hosted, i.e. you could run SimpleLogin on your server. With our detailed self-hosting instructions and most of components running as Docker container, anyone who knows ssh is able to deploy SimpleLogin on their server.
- You can send/reply emails from alias. There's no limits on the number of sends/replies.
- Unlimited bandwidth.
- No ads, no tracker.
- Not just email alias: SimpleLogin is also a privacy-focused and developer-friendly identity provider that:
- respects user privacy
- is simple to use for developers.
SimpleLogin offers a privacy-focused alternative to the "Login with Facebook/Google/Apple" buttons.
- Plenty of features: browser extension, custom domain, catch-all alias, OAuth libraries, etc. and much more to come.
- Open roadmap at Trello: you know the exciting features we are working on.
Our revenue comes only from subscriptions, that means the product will stay ad-free forever.
This is probably the hardest question that a company has to answer :).
As we are using SimpleLogin on a daily basis, for both our personal and professinal usage, in the worst case, we will close registrations for new users so SimpleLogin can only be used by existing users.
For information, Spamgourmet, a similar email forwarding service has been running for more than 20 years now. Spamgourmet is actually an inspiration for SimpleLogin.
If all this is still not enough, you can also run a SimpleLogin instance yourself as SimpleLogin code is open-source and we give detailed instructions on how to run it.
These 2 features both allow you to create alias on-the-fly, meaning you don't have to open SimpleLogin to create a new alias.
Enabling catch-all on your domain allows you to use ANYTHING@my-domain.com as alias with ANYTHING being any word. The only limit is it has to have less than 128 characters.
Alias Directory is similar to catch-all, you can use your_directory+ANYTHING@simplelogin.co as alias. your_directory is the name of the directory you created.
You can reply directly from your email client. Just click on the "reply" button, the reply will be routed via SimpleLogin and SimpleLogin will make it coming from your alias. Your personal email will stay invisible to the original sender.
Technically, the From header in your email is replaced by a special alias dynamically generated for each sender. When you reply, your reply is actually sent to this special alias and SimpleLogin will relay the reply back to the sender, making sure the email is sent from your alias. All information about your personal email address is removed during that process.
A reverse-alias is a special alias that allows you to send email from your alias.
A reverse-alias is created for each alias you want to send email from and each contact you want to send email to.
When you send an email to a reverse-alias from your personal email, the email will be sent from your alias to the contact.
As a normal email address, an email alias is always there unless you delete it.
We use UpCloud, a Finland cloud provider. Our server is currently located in its France-Germany and Netherlands datacenter.
That's a very good question! Do you know that Facebook and Google use these buttons to track
your users browsing history so that they can provide more personalized ads? And do you get any of
these ad-generated revenue?
SimpleLogin, with a transparent pricing model (you know where our revenue comes from) with a single product that focus solely on improving the login experiences yet still giving users total control over their data, does not have any incentive to utilize your user data.
In addition, we believe in a fair model: users come to your website because your website brings value to them and we are in a win-win relationship, so you deserve to have a share of the benefit.
About Apple, they claim to not selling your users data to advertisers but being an advertiser
themselves, how can we be sure ...
Apple can also be considered as an ad platform with their Apple Search Ads so better to not put Apple in a (much) higher position than Facebook or Google in terms of privacy.
Arguments about transparent pricing and fair model apply to Apple too 😉
SimpleLogin code is fully open-source on Github and can be self-hosted. Anyone can freely audit the code or setup their own SimpleLogin server.
SimpleLogin revenue is based on a transparent and sustainable model that allows us to have a privacy-first and tracker-free product.
Yes absolutely! We started with the web platform simply because they can be used for mobile app as well via a Android WebView or IOS UIWebView. We plan to provide a SDK and some examples for Android, iOS, Windows quite soon. Stay tuned!
The current advertising model is based on an unfair model where big players (Google, Facebook, etc)
take almost all benefit and app/content creators get almost nothing. We strongly believe a
sustainable model should be fair: our partners should get an important part of the revenue because
together with SimpleLogin, we provide a great login experience to user while respecting user privacy
at the same time.
The revenue formula is still work-in-progress as we need to take into account different factors (mostly payment processing fee and tax rate) but hopefully this can give you a rough idea on how it works.
The payment period is monthly and works as following:
- a user John opts for the premium subscription. John pays 20$/year. After processing fee and taxes, let's assume SimpleLogin receives 12$ net (this number is quite optimist in France 😉), which is 1$/month. Half of this will be distributed to partners.
- John uses N apps that implement SimpleLogin: each app will get an equal part of the revenue.
Let's put this into a concrete example. The following numbers are of course hypothesis.
- the average number of app a user uses per month is about 10, half of them implement SimpleLogin, that makes N=5.
- you have a website/app that has 1M users, half of them use SingleLogin and 10% of them are paying customers, that is 1 000 000*0.5*0.1=50 000 paying users.
Using our formula, each month you will receive:
monthly_revenue = total_number_of_paying_user * 1/2 * monthly_net_revenue / average_app_number
monthly_revenue = 50000 * 1/2 * 1 / 5 = 5000$
When your subscription ends, all aliases you created continue working normally, both on receiving and
sending emails. Concretely:
- All aliases/domains/directories/mailboxes you have created are kept and continue working normally.
- You cannot create new aliases if you exceed the free plan limit, i.e. have more than 15 aliases.
- As features like catch-all or directory allow you to create aliases on-the-fly, those aliases cannot be automatically created if you have more than 15 aliases.
- You cannot add new domain, directory or mailbox.
For example, if you have 100 aliases by the time your subscription ends, these 100 aliases will continue receiving and sending emails normally. You cannot however create new aliases.
If you are in the free plan, you cannot create new aliases when you reach the maximum number of aliases
(i.e. 15 aliases).
Aliases that would otherwise be created automatically via the catch-all domain or directory feature also cannot be created.
We offer students a premium license for free during the scholarship. Just send us an email to firstname.lastname@example.org from your school email (typically a .edu address) along with your SimpleLogin account so we can upgrade your account to 1 year of premium plan. If you don't have a school email address, a copy of your student card or another equivalent document suffices.
By the end of each period (i.e. every year), you'll receive a reminder email to renew the license. If you are a student by that time, please send us another email from your .edu account for verification so that your license can be extended for another year.
We also offer important discounts or free premium for:
- professors or technical staffs working at an educational institute
- activists, dissidents or journalists
- charity organizations
Please send us an email at email@example.com for more info.
We use Paddle for handling payments and Paddle currently supports the
following payment methods:
- American Express
- Diners Club
- Apple Pay
- Wire Transfers (ACH/SEPA/BACS)
More information can be found on Paddle supported payment methods.
Send us an email at firstname.lastname@example.org if you want to use other payment options (e.g. IBAN transfer, Cryptocurrency, etc).
No we don't have a refund policy because SimpleLogin has a trial period where you can try all premium features.
