Even after comparing dozens of email security services, you may still feel like you don't know how to choose the right mail security software for yourself as an individual or for your company.

  • Provides adequate protection
  • Offers strong filtering accuracy
  • Includes phishing protection
  • Encrypts data
  • Is customizable to meet your needs

Protect Your Inbox Even More With Clean Email

Mail addresses, especially those that are publically available, can be added to spam lists and bombarded with malicious messages. Clean Email’s Screener feature can help by intercepting these unwanted messages before they even reach your inbox. There, you can allow or block them in a secure environment.

However, email security shouldn't just focus on preventing attacks but also on emphasizing organization and effective inbox management. A cluttered and disorganized inbox makes it easier to overlook important messages or accidentally click on a malicious link.

For instance, the Unsubscriber feature can be the first step towards reducing the amount of clutter in your inbox. With just a few clicks, you can quickly unsubscribe from multiple newsletters and promotional emails at once, saving you time and making it easier to focus on trustworthy messages from real senders.

Moreover, the Auto Clean feature lets you set up automated rules to automatically move, delete, archive, or take other actions on emails based on criteria like sender, subject, age, and more. This helps keep your inbox organized and greatly reduces the chance of accidentally clicking on a spam link buried under a pile of unread messages.
