No visibility after send
Mail can fail silently when the site uses weak default delivery. Logs help teams see source, transport, inbox, status, and error context.
Free WordPress SMTP Plugin
Make WordPress email delivery feel less fragile.
Stafflancer SMTP gives site owners and agencies a cleaner way to route WordPress email through SMTP or Microsoft OAuth2, test sending, manage multiple inboxes, and see what happened when a message fails.

Why it matters
WordPress email should not disappear into a black box.
Contact forms, account emails, order messages, password resets, and admin alerts all depend on email delivery. This landing page positions Stafflancer SMTP as a practical free tool for making that workflow clearer and easier to test.
Multiple senders, one site
Agencies often need separate inbox configurations for different sender identities, brands, clients, or delivery tests.
Modern Microsoft sending
Microsoft OAuth2 support helps connected inboxes send through Microsoft Graph when that transport is selected.
Fast confidence checks
Send test emails directly from wp-admin to verify the active transport before relying on important site notifications.
Setup flow
Configure, activate, test, and monitor from one simple workspace.
This free-plugin landing page avoids Pro/pricing sections and focuses buyers on the real value: getting WordPress mail out through a trusted transport with enough visibility to diagnose issues.
- Create more than one sender inbox when a site needs separate sender identities.
- Use SMTP settings or Microsoft OAuth2 depending on the active transport.
- Send a test email before relying on critical WordPress notifications.
- Review mail activity rows when delivery needs troubleshooting.
01
Create an inbox
Add a sender label, From name, From email, SMTP settings, or Microsoft OAuth2 app details.
02
Select the transport
Use classic SMTP for sending paths like Gmail, Zoho, SendGrid, Mailgun, Amazon SES, or Microsoft OAuth2 for Microsoft Graph sending.
03
Set the active inbox
Choose the configuration WordPress should use so the site sends through the correct sender identity.
04
Verify and log
Send a test email, verify Microsoft connection health, and review mail log rows when something needs attention.
Free capabilities
Free SMTP tools that make WordPress email easier to trust.
Give site owners a professional email delivery workspace with multiple sender inboxes, guided SMTP setup, Microsoft OAuth2, test sends, logs, and connection warnings.
Multiple inbox management
Store more than one sender configuration and keep each inbox isolated with its own label, identity, transport, and connection settings.
Useful for agencies, client sites, staging checks, or different sender identities.
Manual SMTP setup
Start faster with presets for common sending paths while still allowing manual SMTP configuration when a host needs custom values.
Designed for real-world SMTP sending paths, not just one narrow sending path.
Microsoft OAuth2 connection
Connect Microsoft inboxes, store token bundles per inbox, verify connection health, and send through Microsoft Graph when active.
Includes reconnect, disconnect, verify connection, and token health visibility.
Test email action
Send a test email to confirm the selected inbox and transport work before relying on password resets, forms, orders, or admin notices.
When Microsoft OAuth2 is active, tests send through Microsoft Graph.
Mail activity log
Review message activity with source, inbox, transport, status, and message details so site owners are not guessing after failures.
The log row cap can be adjusted for lighter or deeper troubleshooting.
Connection health warnings
Surface token expiry, refresh issues, and From Email mismatch guidance so admins know what needs attention before sending fails.
Practical visibility for Microsoft 365 and Outlook-connected sites.
Sending paths
Built for common WordPress email setups.
This section now shows only the sending paths the landing page should confidently promote, without listing unsupported provider-specific services.
