What you get
SPF + DKIM + DMARC aligned
Every send is authenticated. Gmail, Outlook, Apple Mail, Yahoo all see your real domain — never wordpress@yourhost.
AI abuse + spam scoring
Inline classifier catches outbound spam in <80ms. Your IP reputation stays clean even when forms get hammered.
Live delivery dashboard
Every send, open, click, bounce — per-platform, per-form, per-recipient. Webhook events you can pipe into your own analytics.
Queues during outages
If a downstream provider goes dark, we hold the message and retry. Never lose a form submission.
FAQ
How long does setup take?
Three minutes if you already have a SecureSMTP account, five if you don't. The WordPress plugin handles everything — there's no DNS step in zero-config mode.
Do I need to change my domain or sender address?
No. WordPress keeps sending from whatever email you configure — we just sign and route it through authenticated infrastructure. Your customers see your real domain.
What happens if SecureSMTP has an outage?
The WordPress plugin falls back to the default wp_mail() handler so nothing is lost. We retry through SecureSMTP automatically when the relay comes back.
Can I use my own domain for sending?
Yes — and we recommend it. Verify your domain in the dashboard (one TXT record + one CNAME for DKIM) and everything sends from your address with full SPF + DKIM + DMARC alignment.
