Trigger the email
Submit a contact form, reset a password, place a test order — anything that calls wp_mail().
Every email your sandbox sends, captured
wp_mail() is intercepted and logged so you can confirm a contact form, password reset, or receipt actually fired — without ever delivering to a real inbox.
Capture active Never delivered
Your order is confirmed [email protected]
Password reset requested [email protected]

Trigger, land, open, confirm
Watch it land
The message appears in the Email Log tab in seconds. Nothing left the sandbox.
Open the message
Read the exact rendered HTML in an isolated frame, plus recipient, headers, and attachments.
Confirm it fired
Now you know the form actually sent — no “did it work?” guessing, no real inbox required.
Real messages, captured safely
wp_mail capture
Every send, recorded
SandyWP intercepts WordPress mail before it leaves. Subject, recipient, headers, and body land in the log instead of vanishing into a missing sendmail.
Isolated preview
See the real message
The HTML body renders in a sandboxed frame exactly as the recipient would see it — styles, buttons, and all — with a plain-text fallback when that’s what was sent.
Safe by default
Nothing leaves by accident
With no SMTP configured, sandbox mail is captured and never reaches a real inbox. Add your own SMTP plugin — Resend, FluentSMTP, Google Workspace — and it sends for real, still logged here.
Open a message and see exactly what shipped
The rendered HTML loads in an isolated frame — the same email your users would have received. Recipient, headers, and attachments sit right beside it.
- ✓ Sandboxed HTML preview, styles intact
- ✓ Full headers and recipient list
- ✓ Plain-text fallback when that’s what was sent

It works.
This message was sent through wp_mail and captured safely inside your sandbox.
What developers ask
Is any email actually delivered?
Not unless you ask for it. Out of the box there’s no SMTP relay, so mail is captured inside the worker and never reaches a real address. Install an SMTP plugin with your own credentials and delivery goes through as normal.
Do I need to configure SMTP?
Only if you want real delivery. wp_mail() is intercepted automatically the moment the sandbox boots, so capture works with zero setup. Configure an SMTP plugin and SandyWP steps aside for sending while still logging every message.
Can I use FluentSMTP, WP Mail SMTP, or Resend?
Yes, any of them. Mail leaves through your provider under your own credentials and domain, and the log records whether each message was sent or rejected — including the SMTP error when it fails.
Can I turn capture off or clear the log?
Yes. The Email Log tab has a one-click toggle and a clear button. Turning it off only stops recording new messages; it doesn’t change whether they’re delivered.
Does the log survive a reset?
A reset returns the sandbox to a clean slate, including the captured email. Fresh site, empty inbox.
Stop guessing. See the mail.
