Delivery Accounts

Fine-grained control over how your emails are sent. Delivery accounts are send-only connections for when you need a lightweight outbound channel.


When to use delivery accounts

Use delivery accounts when you:

  • Need a send-only connection without full inbox access
  • Want to use SMTP credentials instead of OAuth
  • Have a dedicated sending service separate from your reading mailbox

For most users, a Gmail API mailbox is the better choice since it includes both sending and receiving.


Add a delivery account

  1. Navigate to OneBox > Account
  2. Click Add Delivery Account
  3. Choose the transport type:
    • Gmail SMTP — Send via Gmail’s SMTP server
    • Custom SMTP — Use any SMTP provider
  4. Enter your credentials:
    • Email address
    • Password or app-specific password
    • SMTP host and port (for custom SMTP)
  5. Click Test Connection to verify
  6. Click Save

Test your delivery account

After adding an account, always test it:

  1. Click Test next to the account
  2. WorkOnward Reach attempts to authenticate and send a test message
  3. You’ll see a success or error message
⚠️

Use app-specific passwords for Gmail. Regular Gmail passwords don’t work with SMTP if you have 2FA enabled. Generate an app-specific password in your Google Account settings.


Set a default delivery account

Just like mailboxes, you can set a default delivery account:

  1. Find the account in the list
  2. Click Set as Default

The default delivery account is used for transactional emails (welcome emails, password resets) unless overridden.


Tips

  • Separate outreach from transactional — Use a mailbox for campaign outreach and a delivery account for system emails
  • Monitor delivery health — Test connections periodically to catch credential expiration early
