1. Outlook

  • Compatibility: Android , iOS
  • Price: free

Microsoft’s email client is a powerful tool with integration with other Email service providers. One of the advantages of Outlook is the possibility of linking accounts from other email services, such as Gmail and Yahoo , allowing the registration of up to 20 different addresses in the app.

Outlook can be divided into three main fronts: the inbox, the search and the calendar. The first option sorts the most recent emails and sorts between highlights and filters. For sending, it allows setting up of automatic messages, signatures and creation of groups with contacts. The search tool stands out for its features, such as the option to quickly search for specific events, contacts or attachments.

In addition to organizing e-mails, Outlook can be used as an agenda and has integration with tasks created in Microsoft To Do. You can, for example, import schedules created by Bing with sports calendars and TV schedules. The app’s interface is customizable, with different themes and colors, and the platform has widgets for the home screen.

2. ProtonMail

ProtonMail Email App is a security-focused email client offering encrypted protection for your messages. Unlike other options in the list, where you can link an account created in another service, the application requires you to create your own email address to use. In conversations between two accounts created on the service, end-to-end encryption can be used automatically.

In the inbox, ProtonMail provides shortcuts for quick actions when swiping the screen, but limits the creation of folders and filters for the paid version. While exchanging conversations, you can configure messages that self-destruct and manually activate encryption for sending to contacts from other services.

The free version of the platform, however, only offers 500 MB of space for the inbox. In the paid version, the limit is expanded to 5 GB, there is the possibility of adding up to five different accounts and the creation of folders and filters is free.
