Most WordPress hosts try to send mail from PHP via the local server, which has no proper sending reputation — so big mailbox providers (Gmail, Outlook, Yahoo) silently quarantine or drop it. SecureSMTP routes wp_mail() through an authenticated relay with proper DKIM, SPF, and DMARC alignment, so messages land in the inbox instead of spam.
No. We rate-limit, we don’t deactivate. If you exceed your monthly form-submission or mail-send quota, the form still accepts submissions — the email notification just queues until the quota resets or you upgrade. Your site never breaks.
Yes. Every paid plan — Starter, Pro, and Business — comes with a 14-day free trial, and no credit card is required to start. You get the full plan’s features and limits for the trial period; add a payment method any time to keep your plan, or do nothing and you’ll drop back to the Free plan when the trial ends.
Yes. Upgrade or downgrade at any time from your dashboard. Annual plans are prorated. There are no setup fees and no long-term contracts.
Yes. The Free plan gives you 100 form submissions per month and basic wp_mail relay (sent from our shared domain). All core delivery analytics included. No credit card required, no expiration.
Yes — on the Starter plan and above, you can verify a custom sending domain (we walk you through the DKIM + SPF DNS records). Once verified, every email goes out aligned to your own domain instead of ours, which is the right setup for any production WordPress site.
Yes. Partners share a referral link (e.g. securessmtp.com/ref/zainsaeed) and a coupon code applied at Stripe checkout. The discount is applied automatically when you subscribe through their link.
Yes. We offer 50% off all paid plans for registered nonprofits, K-12 schools, and accredited universities. Contact us with proof of status and we’ll set it up.
We process form submissions and email events to give you delivery analytics, store them in EU/US regions only, and never sell data. Custom data-residency and DPAs are available on Enterprise. SecureSMTP is operated by Technologia FZE, registered in Sharjah, UAE.
Yes, on the Enterprise plan. You can re-brand the entire dashboard, provision sub-accounts per client with isolated billing and analytics, and route their wp_mail through a dedicated sending domain — perfect for managing 10+ client WordPress sites in one place.
Spin up a workspace, connect your first site, and send authenticated mail in minutes. No credit card required.
