Organization-Wide Email Addresses

When sending email from Salesforce, users with these profiles can select their own email address or the organization-wide email address for the email’s From field. Replies are delivered to the selected address.

Also you can set up a special purpose organization-wide email address for Salesforce to use when no reply is expected. Users can’t select this email address. It’s set up to be used by certain features.

Example

Your org has several users assigned to a Support Profile. This profile is associated with an email address called support@acme.com and a Display Name of Acme Support. When these users send an outbound email through Salesforce, they can choose to have their From email address appear as support@acme.com instead of their own Salesforce email address.

The highlighted sections in the following image represents the changes to the From address and Display Name that the recipient of an email might see.

• Considerations for Using Organization-Wide Email Addresses
  Before creating organization-wide addresses and assigning them to your Salesforce user profiles, review a few details, including information about mass emails and reporting.
• Set Up Organization-Wide Email Addresses
  You can define and manage organization-wide addresses for each permission set or user profile. When sending email from Salesforce, users with these permission sets or profiles can select their own address or the organization-wide address for the email’s From address. Replies are delivered to the selected address.
