Whitelist meaning email

In the context of email, a whitelist is a list of email addresses or domains that are allowed to send emails to a specific email account or organization. In other words, it's a list of trusted senders that are not considered spam.

Here's how it works:

  1. An email account or organization sets up a whitelist to specify which email addresses or domains are allowed to send emails to their inbox.
  2. When an email is sent from a whitelisted address or domain, the email server or spam filter checks the sender's IP address or domain against the whitelist.
  3. If the sender's IP address or domain matches one on the whitelist, the email is considered legitimate and is delivered to the inbox.
  4. If the sender's IP address or domain is not on the whitelist, the email may be flagged as spam or blocked altogether.

Whitelisting is often used to:

  1. Allow trusted senders to send emails without being flagged as spam.
  2. Prevent spam emails from being sent to an email account or organization.
  3. Improve email deliverability and reduce the risk of emails being marked as spam.

Common examples of whitelisted senders include:

  1. Friends and family members who regularly send emails to your account.
  2. Official email addresses from companies or organizations you do business with.
  3. Newsletters or subscription-based services that you've opted-in to receive emails from.

To add an email address or domain to your whitelist, you'll typically need to follow these steps:

  1. Check your email account settings or preferences.
  2. Look for a section related to spam filtering or email whitelisting.
  3. Add the email address or domain to the whitelist by entering it in a text field or selecting it from a list.

Remember to only add trusted senders to your whitelist to avoid inadvertently allowing spam emails into your inbox.
