Get Your Salesforce Emails into the Inbox
SMTP Relay connects your Salesforce org to SendGrid, Mailgun, Office365 or any SMTP server — improving deliverability and giving you full control over your email.
Why Companies Use SMTP Relay
Improve email deliverability
Salesforce's shared sending reputation can land your emails in spam. Route through your own authenticated mail server for better inbox placement.
Remove "via" and "on behalf of" labels
Recipients see "sent via Salesforce" or "on behalf of" when Salesforce delivers email. SMTP Relay removes those labels so emails look like they came directly from you.
Use your own mail server with Salesforce
Salesforce doesn't support authenticated SMTP servers natively. SMTP Relay bridges the gap so you can use SendGrid, Mailgun, Office365, or any SMTP server.
How It Works
SMTP Relay securely sits between your Salesforce org and a third-party mail server. It checks and maps all outgoing messages, ensuring the best delivery for your email.
