Reliable WordPress email — for every form plugin you already use.

Comparison reflects each vendor’s default behaviour as of 2026-06. Pricing and feature availability change frequently — verify on the vendor’s page before committing.

• Do I need a separate SMTP plugin alongside SecureSMTP?

  No. SecureSMTP catches everything wp_mail() does — every form notification, every password reset, every WooCommerce receipt. Installing WP Mail SMTP or Post SMTP alongside SecureSMTP isn't required and can cause conflicts.
• What if I already have WP Mail SMTP installed?

  Disable it. SecureSMTP detects a competing SMTP plugin and shows a warning in WP-admin pointing you to the conflict. You can keep your old plugin around for a day or two to roll back, but for routing to work, one of them has to be in charge.
• Does SecureSMTP work with Gravity Forms, Ninja Forms, and WPForms?

  Yes. Any plugin that uses wp_mail() — which is virtually all of them — is automatically routed through SecureSMTP as soon as Email Delivery is enabled. No per-plugin integration code or configuration is required.
• What about Gravity Forms notifications that bypass wp_mail()?

  Caught by our PHPMailer interceptor in plugin v1.18+. If a plugin instantiates PHPMailer directly (skipping wp_mail), we still hook the send method and route the outbound message through SecureSMTP.
• Can I send as my own domain (yourbusiness.com)?

  Yes — via DKIM setup, free on all paid plans. You add a TXT record to your DNS and SecureSMTP signs outgoing email with your domain. Inboxes see the email coming from "you", not from SecureSMTP. Step-by-step guide is in the SecureSMTP dashboard under Sender Domains.
• What happens if SecureSMTP is ever down?

  Fail-safe fallback to WordPress's native PHP mail — your email is never silently dropped. The plugin logs the fallback so you know when it happened. Native delivery is less reliable than SecureSMTP, but it's strictly better than the email vanishing.
• Do my emails count against my form-submission limit?

  No. Email Delivery has its own per-plan quota separate from form submissions. You can use one without the other — e.g. send only password resets through SecureSMTP without sending any form submissions through it.
• Where do I see what's been routed?

  Two places: in WP-admin under QCS Forms → Mail Log (last 200 messages, real-time), and on the SecureSMTP dashboard at securessmtp.com/app/forms/email-log (full history, searchable by recipient, subject, or status).
• Is this faster than my host's SMTP?

  Yes, in most cases. Shared-hosting SMTP is often rate-limited and routed through cold IPs that mailbox providers down-score. We send from Resend's IP-warmed pools with pre-established sender reputation, so deliverability is meaningfully better — and latency is usually lower too.
• What's the catch?

  None. The free tier is 100 routed emails / month, forever — the same quota as form submissions on the free plan. Paid tiers exist only for higher volume; every reliability feature ships on the free tier too. If you outgrow the free quota, paid plans start at $7/mo.
