The delivery journey
What happens when a customer hits “Send”.
Every submission passes through five defense layers before it becomes an email in your inbox. This is the path.
See it in five minutes
From wp-admin to inbox — three moves.
The whole setup is done before your coffee cools. No dev-ops, no ticket queue, no sales call.
Install the plugin.
Add SecureSMTP for WordPress from wp-admin, or paste our SMTP host into WP Mail SMTP, Post SMTP, Fluent SMTP — anything that speaks SMTP works.
Verify your domain.
Copy the two DNS records we generate (SPF + DKIM). Add them to your DNS. We poll for verification every few seconds — no waiting screen.
Watch it deliver.
Send the first test email. Watch the delivery log flip from Queued → Delivered. Your client’s contact form now lands in the inbox — every time.
The difference
Same form. Same customer. Two very different endings.
Without SecureSMTP, your WordPress email lands in Gmail's spam folder. With SecureSMTP, it lands in the inbox — every time.
Default WordPress email
wp_mail() with no auth · Gmail flags it · lands in Spam.
✗ No SPF alignment
✗ No DKIM signature
✗ Fails DMARC checks
Authenticated relay
Signed with your domain · Gmail trusts it · lands in Inbox.
✓ SPF-aligned sender
✓ DKIM-signed body
✓ DMARC-compliant delivery
The dashboard
Every send, logged. Every failure, flagged.
Real-time delivery log with status, opens, clicks, bounce reasons — one screen your team already knows how to read.
- Green pill = delivered · red = bounced. No decoding.
- Per-site filtering when you manage multiple clients.
- Bounce reasons in plain English — with the fix.
- CSV export for compliance / audit needs.

5-layer stack
Every submission goes through all five.
Layered defense means an attacker has to defeat all five checks at once — in practice, they move on.
01
Honeypot field
Silent trap
Hidden field bots fill, humans never see. First cut.
02
Rate limit
Cap abuse
5 submissions per minute per IP. Bots throttle, humans don't notice.
03
HMAC signing
Cryptographic proof
Constant-time signature verify. Spoofed sources land in 401.
04
DKIM + SPF
Domain aligned
Every notify email signed as yours. Gmail trusts on first delivery.
05
AI classifier
Second opinion
Borderline submissions get a second check by an AI model. The result is shown with the submission.
Real teams say
The freelancers and agencies fixing forms today.
“Been fixing WP contact forms on Fiverr for two years. This is the first tool where I stopped debugging SMTP settings and started billing for the setup itself.”

Priya M.

Common questions
Everything answered before you sign up.
What’s the catch with the free plan?+
None. 5,000 emails / month covers most personal sites and small businesses. When you hit the cap, sends pause until next month or you upgrade. Nothing gets billed automatically. No card on file to worry about.
Do I need to install a WordPress plugin?+
For WordPress sites, either our official plugin (one-click install) or you can point WP Mail SMTP / Post SMTP at our relay using our SMTP host and port. For non-WordPress sites, paste our SMTP credentials into your platform’s email settings.
How fast can I get my first email delivered?+
Account creation to first delivered email: ~5 minutes for WordPress (install plugin, paste API key, verify DKIM). Non-WordPress platforms take 10-15 minutes depending on how their SMTP configuration works.
Does the pixel on this page do anything to my account?+
No. This page tracks conversions for our own advertising so we can measure our ROAS. It doesn’t affect anything on your side. If you’re here from a Meta ad, the signup is counted as a conversion on our end.
What if I need to send more than 5,000 emails / month?+
Upgrade to Starter ($7/mo, 50,000 emails) or Pro ($19/mo, 250,000 emails). You can upgrade any time from the dashboard — the cap on the free plan just resets each month if you don’t.
