We use email for a variety of tasks in our daily lives. Your inbox will quickly become cluttered and unmanageable. These free email apps address common email concerns such as privacy, organization, and overload.

Email has been around almost as long as the internet. It’s no surprise, then, that the changes you see in new email apps and services are minor tweaks rather than revolutionary new features.

Even so, these minor adjustments are significant. That alone should motivate you to safeguard your data. If you want to stop feeling overwhelmed, you’ll need to set up better ways to manage your inbox.

These apps go above and beyond what Gmail and Outlook have to offer.

Skiff

Anyone can use Skiff Mail’s 10GB of free storage space. There are no loopholes or requirements to “send an invitation to someone.” This is the basic package you get when you sign up.

This makes it the first viable free alternative to Gmail, because the storage space has always been a barrier to switching. Yes, it is end-to-end encrypted, which means that not even Skiff can read your emails.

The email app itself looks and works exactly like any other modern email app. You can search within your emails, sync with mobile apps, create filters and rules, and apply labels, among other things.

Skiff also offers Skiff Pages, an encrypted Google Docs alternative that replicates the same features while protecting your privacy.

Shortwave

Shortwave detects that you use your inbox as a to-do list and concentrates on that. By default, all email is grouped by sender or conversation.

This eliminates the need for multiple tabs for different groups. You can snooze emails, pin important ones to the top of your inbox, and mark the rest as “done” if you don’t want to deal with them right away. You can also reorder emails without being chronological by dragging and dropping them.

You can save a few contacts as “Favorites” and view their correspondence by clicking their name. This is a great way to get updates from your boss or coworker without having to sift through a clogged inbox.

All told, this is the simplest way to sort through your inbox and get back to work.

Shortwave also has “Workspaces” where you can chat with team members in an email chain. This feature didn’t appeal to us; it felt like an inferior version of Slack.

In the free version of the app, Shortwave retrieves the last three months of emails from Gmail. The premium version costs $9 per month if you want access to your entire archive. Shortwave also claims to be working on an Android version.

Sleek

Sleek is a Gmail-based email app that helps you get to inbox zero in a natural way.

Sleek allows you to import emails from one or more Gmail accounts. After they’re all in, Sleek organizes them by sender or sender domain.

For instance, the domain of your workplace will deliver all emails from your workplace, whereas our boss’s email address will deliver all emails from our boss. The goal is to use these groupings to take action quickly.

In addition, Sleek provides a few shortcuts. The “Move Emails” button, which uses groups, allows you to perform an action on hundreds of emails from a domain at once, such as archiving all of your Amazon purchases and updates. Certain types of emails can also be routed to labels, bypassing the inbox and appearing only in that label.

Even with Sleek’s help, getting to inbox zero will take some time if you have a large backlog of emails. However, it will be much faster than trying to do it manually in Gmail.
