What Is Mailyard?

Mailyard is a WordPress SMTP plugin with a backup plan. Connect Amazon SES, Postmark, Resend, Brevo, or any SMTP server, and every email your site sends — password resets, WooCommerce receipts, form notifications — goes through a real email service instead of your host’s mail server. And if that service fails, Mailyard switches to your backup on the same send, so the email still goes out.

Mailyard is free — download it from WordPress.org.

Why does WordPress need an SMTP plugin?

Out of the box, WordPress hands wp_mail() to your web host, and most hosts are bad at email: no proper SPF/DKIM authentication, shared IPs with bad reputations, silent failures. Messages get blocked, land in spam, or vanish without a trace — which is why “WordPress not sending emails” is one of the most common problems on any support forum. Mailyard fixes it by routing email through a provider that’s actually built for it, and keeps it fixed when that provider has a bad day.

What you get — all free

  • Automatic email failover — a backup provider takes over the moment the first one fails, on the same send, not in a retry queue.
  • Six ways to send — Amazon SES, Postmark, Resend, Brevo, custom SMTP, or PHP mail.
  • Smart sender routing — the right provider for each kind of mail, automatically, based on the from address or purpose.
  • Full email log — every send and every failure, with the exact provider error.
  • Deliverability checker — grades your SPF, DKIM, DMARC, and MX records A–F and hands you the exact DNS fix.
  • Bounce & complaint tracking — four provider webhooks, tidied into one clean mailyard_bounce hook.
  • AI agent tools (MCP) — let Claude, Cursor, or Codex diagnose your email problems, with per-tool permissions.
  • 60-second setup — pick a provider, paste a key, send a test.

Everything you see is free. No locked buttons, no crippled features, no upgrade nags.

Is Mailyard an alternative to WP Mail SMTP, FluentSMTP, or Post SMTP?

Yes. Mailyard does the same core job — routing wp_mail() through a real email service — and adds the things most of them don’t have for free: automatic failover on the same send, sender routing across multiple providers, bounce and complaint tracking, and a built-in deliverability checker. Anything that sends mail the normal WordPress way — WooCommerce, Contact Form 7, Gravity Forms — goes through Mailyard automatically, with no per-plugin setup.

What about sending campaigns?

Mailyard itself is a delivery engine. If you also want to send broadcast email — campaigns, contacts, open and click tracking — that’s Mailyard Pro, a separate paid plugin that uses Mailyard as its delivery engine. Mailyard never nags you about it, and nothing in the free plugin is held back for it.
