It’s a familiar story. You sign up for an account with a website and hand over your email address. Sometime later, the website gets hacked and your email address ends up in the hands of the bad guys. Cue an inbox overflowing with emails from spammers and scammers. 

Enter SimpleLogin, a service claiming to solve that problem. As someone who had to switch email addresses after my old one was leaked in no less than five data breaches, I was excited to try out a way to keep my new address private.

In this review, I’ll explain what SimpleLogin is and how to use it, as well as covering its pros and cons, safety and pricing. But for those of you who don’t want to read the whole thing, I’ll start with a brief summary.

Review Summary

SimpleLogin creates email aliases, i.e. alternative email addresses, that forward mail to your real address. It’s made for anyone who wants more to stay private online and reduce the amount of unwanted emails they receive.

Pricing: SimpleLogin has a free plan as well as a $30 a year premium plan with extra features.

What is SimpleLogin?

SimpleLogin is an email masking service that helps keep your email address private.

Once you sign up, you can generate alternative email addresses called aliases and give them out in place of your real email address. They look something like this: getcookie_tintype@simplelogin.com.

You can use an alias when you sign up for a new site or online newsletter, or even give one to people you don’t know that well who want to keep in touch. 

When an email is sent to an alias, SimpleLogin forwards it to your real email address, so it ends up in your regular inbox. If you reply to it, SimpleLogin makes sure your response looks like it comes from your alias, not your real email. 

Is SimpleLogin safe?

As SimpleLogin forwards your emails, it’s good to consider whether it’s trustworthy before you decide to use it.

Fortunately, there are two good reasons to trust SimpleLogin. The first is that it is now owned by Proton AG, the well-respected company behind privacy-focused ProtonMail. The second is that its code is open-source, meaning anyone can look at it and check it’s not doing anything it shouldn’t.

How much does SimpleLogin cost?

SimpleLogin has a free plan that allows you to generate 10 email aliases and forward them to 1 mailbox, i.e. real email address.

It also has a premium plan, which costs $30 a year or $4 a month. This gives you access to unlimited email aliases which can be forwarded to unlimited mailboxes, i.e. real email addresses, allows you to connect unlimited custom domains, generate aliases on the fly, and more.

How do I use SimpleLogin?

Once you sign up, SimpleLogin gives you your first alias. You can also create new aliases in a few different ways, which I’ll go over below. Then I’ll cover sending emails from an alias, as well as what to do if your alias starts to receive spam.

Creating a new alias

Creating a custom alias in SimpleLogin. The prefix "safenotscammed" is selected and a list of seven available domains is shown, one of which must be selected to finish creating the alias.
Creating a custom alias in SimpleLogin involves selecting a prefix and an available domain.

If you want some choice over how your alias looks, you can create a custom alias. You’ll need to decide on a prefix and then select a domain (with some added random letters and numbers) out of the available options. For example, I chose the prefix “safenotscammed” and the domain (plus random characters) .e66hd@simplelogin.com, giving me the alias safenotscammed.e66hd@simplelogin.com. 

More choice over how your alias looks is possible with the premium plan, as you can connect custom domains, i.e. domains you own. With a custom domain you won’t have any random letters added, meaning you can style your aliases exactly how you want, e.g. staysafe@safenotscammed.com.

Screenshot showing the "Random alias" button in SimpleLogin which has two further options: "By Random Words" and "By UUID."
There are two options for creating a random alias: using words or using a UUID.

You can also ask SimpleLogin to create a random alias, either by using random words or by using a 32 digit universally unique identifier (UUID). These are good options if you want your alias to keep you as anonymous as possible.

When I opted for random words, SimpleLogin generated the alias khor_scrutinizer@simplelogin.com. When I selected UUID, it gave me 9bde97c9-3d9e-4895-b56a-a8e143aeaedf@simplelogin.com

Creating aliases on the fly

If you’re on the premium plan, you can also generate aliases “on the fly,” i.e. without creating them in SimpleLogin before you give them out. This can be helpful if you’re asked for your email address when you don’t have easy access to SimpleLogin, such as when you’re in a store and want to sign up for its loyalty program.

You can generate email addresses on the fly in three different ways: by using directories, subdomains, and custom domains. Each of these requires some setup beforehand to create a basis for the aliases you’ll then be able to generate when you’re away from SimpleLogin.

Directories

Screenshot showing an alias generated on the fly by the directory safenotscammed. The alias is safenotscammed+philosophy@simplelogin.com
I created the directory “safenotscammed” and used it to create the alias: safenotscammed+philosophy@simplelogin.com.

You can create up to 50 directories on the premium plan. I started off by making one called “safenotscammed.” To use your directory to make aliases on the fly, you need to add a “+,” “/,” or “#” to your directory name, followed by a word or phrase and one of the available domains, e.g. simplelogin.com.

For example, I wanted to sign up for a philosophy newsletter, so I entered the not-yet-created alias safenotscammed+philosophy@simplelogin.com into the newsletter sign up form. When the confirmation email was sent, SimpleLogin automatically created the alias for me. 

Subdomains

Screenshot showing the alias philosophy@safenotscammed.simplelogin.com created on the fly using the subdomain safenotscammed.
I created the subdomain “safenotscammed” with the root domain simplelogin.com and used it to create the alias: philosophy@safenotscammed.simplelogin.com.

Subdomains work similarly to directories, but you can only create 5 of them. To set up a subdomain, you’ll first need to choose one out of a selection of domains and then decide what to call your subdomain.

I created safenotscammed.simplelogin.com as one of my subdomains. To create an alias on the fly, choose a word or phrase, then add “@” followed by your subdomain. 

For example, I signed up for another philosophy newsletter using the not-yet-created alias philosophy@safenotscammed.simplelogin.com. Once the newsletter’s welcome email was sent, SimpleLogin created the alias and delivered the email to my real inbox.

Custom domains

The custom domain settings for safenotscammed.email in SimpleLogin. With catch-all turned on, the tip below reads "Simply use anything@safenotscammed.email next time you need an alias: it'll be automatically created the first time it receives an email."
Turn on the “catch-all” option for your custom domain to create aliases on the fly.

The third and final way to create email addresses on the fly, custom domains, is probably the easiest, though you do have to purchase the domains separately and connect them to your SimpleLogin account first.

Once that’s done though, you just have to turn on a setting called “catch-all” for your domain and SimpleLogin will automatically create aliases of the form prefix@yourcustomdomain.com on the fly. 

For example, I connected the custom domain safenotscammed.email to my SimpleLogin account and enabled the catch-all option. So now if I sign up for a philosophy newsletter using the not-yet-created alias philosophy@safenotscammed.email, as soon as SimpleLogin receives the welcome email, it will create the alias for me.

Responding to emails

Once you’ve given out your aliases, you might find you need to respond to an email sent to one of them. SimpleLogin allows you to reply right from your inbox and makes sure your response looks like it comes from your alias. You don’t even have to do anything to set this up—it just works!

If you enter the email address you want to contact and click "create reverse-alias," SimpleLogin will generate an address you can use to ensure your response comes from your alias, not your real email.
If you’re on the premium plan, you can use the reverse-alias feature to initiate emails to a contact.

If you’re on the premium plan, you can also initiate an email sent from your alias, though this is slightly more complicated. You’ll need to go to your SimpleLogin account and find the alias you want to send an email from. Then select “contacts” and enter the address you want to email and click “Create reverse-alias.” You’ll need to put the reverse-alias in the “to” field of your email, write your message, send it, and let SimpleLogin take care of the rest.

What to do if your alias gets spammed

If your alias starts receiving unwanted emails, you have a few options. If the unwanted emails are all coming from one particular address, you can block that address to stop those emails reaching your inbox. 

You can block a contact by toggling the button by their name to "off."
Block a contact by toggling the button by their name to “off.”

You can do this by logging into your SimpleLogin account, going to your alias, clicking contacts, and toggling the button by the offender’s name to “off.”

Disable an alias by toggling the button next to it to "off." Delete it by clicking the "delete" button at the bottom.
If you get too much spam, you can disable or delete an alias to keep unwanted emails out of your inbox.

You can also disable the entire alias, which will stop all emails sent to it from reaching your inbox. Just toggle the button by your alias’s name to “off.” If you want to allow emails through again, you can toggle the button back to “on.”

Additionally, you can delete your alias by clicking the “more” button and selecting “delete.” However, SimpleLogin recommends against deleting an alias, unless it’s a custom domain, because once it’s deleted there’s no getting it back.

What are the pros and cons of SimpleLogin?

I tested out the premium version of SimpleLogin for a week to see how it held up. Spoiler alert: I will definitely keep my subscription. 

During my testing, I used SimpleLogin to sign up for multiple different services, including Twitter, Pinterest, Instagram, and various newsletters without any problem. Only one very niche site would not let me register using my alias. This site explicitly requested you use a real email address to sign up, so it’s not surprising my attempt to use an alias did not work.

One site I signed up for started sending me a lot of email so I used SimpleLogin to block the sender. In my SimpleLogin account, I can see that their address keeps sending emails to my alias, but thankfully none of those messages have made their way to my inbox.

A screenshot showing a list of 10 redacted emails sent to an alias. 6 were from a blocked sender and were not sent to my inbox.
The red “no” sign indicates an email from a blocked contact that SimpleLogin did not forward to my inbox.

I also tested out the ability to send emails using my alias, both by responding to an email and by initiating an email. I used one of my other real email addresses for this so I could check that the emails sent via my alias didn’t leak the real email address I’d used to send them. Fortunately, everything looked just as it should.

One nice feature of SimpleLogin is that it offers mobile apps and browser extensions. This makes it easy to use an alias to sign up for services on mobile, as you can just click on your alias in the app to copy the address. The browser extension also allows you to create an alias and enter it into an online form in one click. While that’s super convenient, I couldn’t figure out how to change the kind of alias that gets generated there, which was a little irritating.

The browser extension creates an icon on email fields that you can click on to generate an alias.

My favorite SimpleLogin feature is the ability to add custom domains. You can use them to create unlimited custom email aliases and, as you can send mail from them too, you’re basically getting functional custom email addresses without the need to pay for separate hosting, which is great!

That’s not to say SimpleLogin is perfect, however. As I mentioned earlier, one site I tried to sign up for wouldn’t let me do so using a SimpleLogin alias. If more sites start doing that, then it’s going to be problematic.

Additionally, I found SimpleLogin’s interface to be unintuitive at times. For example, when I wanted to add an extra mailbox to one of my aliases, I looked under the settings for that alias and couldn’t find an option to add it. I was confused until I realized I needed to add the mailbox to my account via the Mailbox tab first, before the option to add it to an alias would appear in the alias’s settings.

Alternatives

If you like the idea of masking your emails but don’t like SimpleLogin, you can try Firefox Relay and AnonAddy instead.

Firefox Relay offers free email masking and its paid plans include an optional VPN and phone number masking, too. Like SimpleLogin, it is also open source.

AnonAddy is open source, like SimpleLogin, and offers a free plan and two paid tiers.

Final recommendation

SimpleLogin is a great way to keep your email address private. It gives you 10 aliases for free and, if you want more, or if you just want more powerful features, the premium plan is relatively inexpensive at $30 a year. Plus, as SimpleLogin is owned by Proton AG, a respected company in the privacy sphere, you can rest easy knowing it’s a trustworthy service.
