Test the Deliverability of Emails Sent Through Salesforce

When a user sends an email through Salesforce, the email is routed through one of a number of possible Salesforce IP addresses. If the email’s recipient blocks any of these IP addresses, the email might not be received. It’s hard to test whether your customers are receiving emails from all possible Salesforce IP addresses. However, using the Test Deliverability feature, you can easily send an email to yourself from each of the potential Salesforce IP addresses. If you receive all emails, then you aren’t blocking any of the Salesforce IP addresses.

Send Test Messages

These steps apply to both Hyperforce and non-Hyperforce orgs.

  1. From Setup, enter Test Deliverability in the Quick Find box, then select Test Deliverability.
  2. Enter your business email address.
  3. Click Send. Salesforce sends a test message from all IP addresses to your business email address. Each test message specifies the IP address from which it was sent.
  4. To make sure that you received all test messages, check your business email account.

Salesforce maintains separate IP addresses for inbound and outbound email. The IP addresses used for outbound email don’t accept inbound email connections.

Resolve Issues in Hyperforce Orgs

For Hyperforce orgs, Salesforce sends only one test message to your business email address.

If you didn’t receive the test message, your organization’s email administrator should use mutual TLS (mTLS), as explained in Preferred Alternatives to IP Allowlisting on Hyperforce. To ensure you can properly receive mail sent from the Salesforce platform, rely on standard email security protocol, such as, TLS, SPF, and DKIM. See Ensure You Can Receive Email From Salesforce for more details.

Resolve Issues in Non-Hyperforce Orgs

For non-Hyperforce orgs, Salesforce sends a test message from all IP addresses to your business email address. Each test message specifies the IP address from which it was sent.

If you didn’t receive all the test messages, your organization’s email administrator must add the Salesforce IP ranges to the allowlist for your organization’s email server. When you add those IP addresses to the list of trusted addresses, the email server can receive email that might otherwise be blocked. For a current list of Salesforce IP ranges, see Salesforce IP Addresses and Domains to Allow.
