User Email Address Verification

Users can’t send outgoing email from Salesforce until their Salesforce email address and return email address are verified. Learn how to identify users with unverified email addresses and help them complete this required step.

• Manage User Email Address Verification
  Users can’t send outgoing email from Salesforce until their Salesforce email address and return email address are verified. This requirement improves security in Salesforce and reduces the risk of email spoofing and spam. Identify users with unverified email addresses or return email addresses. Then learn how to initiate the verification process.
• Verify Email Addresses with Async Email
  Send email messages to internal and external users to ensure they’re registered with a valid email address that they own. Async email messages contain a verification link (URL). Users simply click the link to verify their email address. After verifying their email address, external users can log in with one-time password (OTP) via email (passwordless login).
• Use a Verified Domain for User-Level Email Verification
  Simplify user management by verifying email addresses at the domain level with DomainKeys Identified Mail (DKIM) or an authorized email domain. When you use these options, email verification isn’t required for users with email addresses on a domain that you own. Before you implement this option, carefully evaluate the security implications.
