What is white list for emails

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

When an email is sent to a recipient, the recipient's email server or email client checks the sender's IP address, domain, or email address against a list of known senders. If the sender is on the whitelist, the email is more likely to be delivered to the recipient's inbox, rather than being flagged as spam or blocked altogether.

Whitelisting is often used to:

  1. Allow specific senders to send emails to a particular email account or domain, such as a company's IT department or a trusted partner.
  2. Prevent spam emails from being sent to a specific email account or domain.
  3. Ensure that important emails, such as password reset notifications or transactional emails, are delivered to the recipient's inbox.

There are different types of whitelists, including:

  1. IP whitelists: List of IP addresses that are allowed to send emails.
  2. Domain whitelists: List of domains that are allowed to send emails.
  3. Email address whitelists: List of specific email addresses that are allowed to send emails.
  4. Sender ID whitelists: List of senders that have been verified as legitimate.

To add an email address or domain to a whitelist, you typically need to:

  1. Check the recipient's email settings or preferences to see if they have a whitelist feature.
  2. Look for a "Whitelist" or "Safe Senders" option in the recipient's email client or account settings.
  3. Add the email address or domain to the whitelist by entering it in the specified field.

Some popular email services that offer whitelisting include:

Keep in mind that whitelisting is not a foolproof method to prevent spam, as spammers can still try to send emails from fake or compromised IP addresses or domains. However, it can be an effective way to ensure that legitimate emails from trusted senders are delivered to the recipient's inbox.
