Everyone knows about Gmail. But what about all of the other free email services out there? Gmail might be the most popular and the most well-known, but that doesn't necessarily mean it's the best.

So what else is out there? Here are some of the best free email accounts you can register for today.

1. Outlook

Outlook (formerly known as Hotmail) was one of the first independent email services to be offered for free. In fact, until it was dethroned by Gmail in 2012, it was the most popular email service in the world.

The service has gone through numerous rebrandings over the years, and its current iteration is one of the best in terms of appearance and user-friendliness. It looks and feels very similar to the other web apps in Office Online, so if you use them, you'll feel at home here.

It has a lot of advanced features, including 100 GB of storage, integration with OneDrive, and support for custom domain names.

2. Yandex.Mail

Yandex is a Russian company that's involved in all kinds of internet ventures, including web search, where it currently ranks as the largest search engine in Russia. Other services include Yandex Browser, Yandex Launcher, and Yandex Disk for cloud storage.

You'll get 10 GB of storage capacity, as well as features such as message timers, customizable interfaces, and a unified inbox.

The interface is solid, too. Not only is it clean and intuitive, but it has most of the features you'd need for an easy time, such as labels, categories, reminders, message templates, and configurable hotkeys.

3. Zoho Mail

The Zoho Corporation is best known for its Zoho Office Suite, which is a good free alternative to Microsoft Office, but its free email service isn't all that shabby either. And best of all, it's really free—there are no advertisements! You can even set up email at your domain for free with Zoho Mail.

Zoho Mail caters to professionals. It has many useful features like multi-level folders, complex rules and filters, tabbed and threaded views, advanced search, message templates, and an interface designed for power users.

After signing up for Zoho Mail, you'll get 5 GB for email storage. If you need more space, you'll have to shell out for a premium subscription.

4. Yahoo! Mail

Yahoo! Mail was one of the big three free email account services back in the day, and while it's still in use by a lot of people, it has certainly fallen by the wayside in recent years.

The interface is simple and straightforward, but not so minimal that it feels outdated or lacking. Its feature set is admittedly a bit basic, but for a web-based email service, it's not bad at all.

And with a 1 TB storage capacity, Yahoo! Mail is basically offering unlimited storage. Attachments are limited to 25 MB in size, which means that even the most avid email user would have trouble filling up that much space in one lifetime.

5. ProtonMail

If security and privacy are the things you care about most in an email service, then ProtonMail is the one for you. Created by a CERN researcher and his research team of Harvard and MIT students, ProtonMail is one of the best free encrypted email providers online.

ProtonMail is protected by Swiss privacy laws and a two-password form of inbox encryption. Emails are also encrypted before being stored, and no metadata is kept (not even your IP address). You can even send self-destructing messages if you're so inclined.

Free users get 5 GB of storage and 1,000 messages per day. Other features include labels, custom filters, folders, and custom domain support.

6. GMX Mail

GMX Mail has been around since 1997, yet surprisingly few people have ever heard of it. It's been popular enough that it was able to acquire Mail.com and its users back in 2010, bringing it up to 11 million active users in 2015.

With GMX Mail, you'll get unlimited email storage, 50 MB attachment file size limit, 65 GB of file storage, and up to 2 levels of nested folders.

GMX Mail comes with cloud file storage, which is a great benefit. And the web client also has a contacts manager and a calendar organizer, both of which are useful.

7. AOL Mail

We bet you didn't know that AOL (formerly known as America Online) is still alive and kicking. In fact, it currently maintains a lot of products, including a search engine, a video player, and a free email service.

AOL Mail offers 1 TB of email storage with a 25 MB limit on attachment file sizes. Other than the basic features you'd expect from a free email provider, AOL Mail doesn't provide much more.

The interface is a bit unpolished and it's supported by ads. Overall, it's neither great nor terrible.

8. Tutanota

Tutanota is a free email account provider that has a strong focus on privacy.

Some of the standout privacy features include encrypted transmission, end-to-end encrypted email storage, contact storage, end-to-end encryption of all internal emails, TOTP for second-factor authentication, and a no-log policy.

You will also get multi-user support, support for custom domains, and alias addresses.

The free version of the app offers 1 GB of storage and support for just one calendar. Paid plans start at €12/month.

9. iCloud Mail

If you have ever signed up for an Apple ID account, you will have an iCloud email address (depending on how old your account is, your address might be @mac.com or @me.com, but they all fall under the iCloud umbrella).

All users get 5GB of storage on iCloud, but keep in mind that the storage is divided across iCloud Photos, iCloud Drive, and your macOS/iOS backups, so you may reach the limit sooner than you think.

10. Guerrilla Mail

We end with Guerrilla Mail. It provides you with a burner email address that you can use when you don't want to enter your real address on a web form or to sign up for a service.

Because it is a burner email, you don't need to make an account to be able to use the service. And unlike some of its competitors, the email address itself will never expire. Instead, only the emails themselves will expire. They will no longer be accessible one hour after they hit your inbox.

It's important to note that emails sent to Guerrilla Mail are not private, so you should never use the app for sensitive communications.

Should You Dump Gmail?

Gmail is perfectly fine, unless you have a specific complaint about one of its features, don't trust it to value your privacy, or want to avoid using Google as much as you can. In that case, you'll want to give these a try.

We urge you to try out alternatives whenever you can. You never know when you may find an alternative that you absolutely love.
