How to whitelist an email in Gmail, Outlook, and Tuta Mail on iPhone, Android and desktop in 2025.

We’ve all experienced waiting for an important email, for example a one-time pin code, to arrive, only to realize it’s ended up in the spam folder of Gmail, Outlook, or Tuta Mail. Setting up a whitelist or safe sender, is a simple and quick solution to ensure the email doesn’t get marked as spam and always arrive in your inbox. Here’s how you can whitelist an address in your mailbox on an iPhone, Android, or desktop.


What does it mean to whitelist an email

While most important emails do arrive in your inbox, sometimes they do get blacklisted and sent to the junk or spam folder by accident. Whitelisting the address is a quick and easy solution to make sure emails from specific domains or senders always arrive in your inbox. Whitelisting an email address or domain or creating a safe sender, simply adds the address to a list that ensures the recipient address sends to your inbox – this is especially useful for emails from services you sign up for or newsletters you subscribe to which often get marked as spam by automatic filters.
