SpamRate — Email Deliverability Testing

Sending newsletters, WooCommerce order emails, or the everyday WordPress emails your site fires — password resets, form notifications, receipts? SpamRate tests where those emails actually land — Inbox, Promotions, or Spam — at real Gmail, Outlook, Yahoo and other mailboxes, without leaving your WordPress admin panel. Not a content score, not a simulation — real emails checked in real mailboxes. The plugin doesn't replace your email service. It tests what your email service delivers. What the plugin does

• Run deliverability tests — send a test email and see where it lands — Inbox, Promotions, or Spam — with a spam-rate score and the technical detail behind it.
• Test your WooCommerce emails — render any store email (new order, completed order, and more) with WooCommerce's own sample data — never a real customer's data — and see where it lands.
• Test your WordPress emails — check the deliverability of your site's own outgoing mail, sent the same way WordPress sends password resets and notifications.
• Manage deliverability monitors — set up monitors and get alerts when deliverability drops (Pro and Max).
• Access full test history — compare results over time and track how your deliverability changes (connected account).
• 19 free diagnostic tools — SPF, DKIM, DMARC, MX, blacklists, BIMI, MTA-STS, DANE, WHOIS, SSL, and more. No SpamRate account required.

Compatible with any WordPress email plugin or service You send a test email through your existing service, and we check where it lands. It works the same whether you send with MailPoet, FluentCRM, The Newsletter Plugin, Mailchimp, Brevo, ConvertKit, ActiveCampaign, Mailgun, Amazon SES, WP Mail SMTP, Post SMTP — or any other SMTP plugin. And every test also analyzes the SPF, DKIM, DMARC and other technical settings behind your mail, so you see not just where it lands but exactly what to fix. SpamRate never sends your mail or reconfigures your server — it measures and diagnoses what your existing setup delivers. Free, and account-optional The plugin is free to install, distributed through the official WordPress.org plugin directory. You get one deliverability test a day per site, plus all 19 DNS tools, with no account at all. A free SpamRate account raises that to 3 tests a day and saves your history; Pro (50 tests a day) and Max (100 a day) add campaign monitors, more test addresses, saved and pinned results, plus PDF reports and password-protected sharing on spamrate.is. Account, upgrades and billing all happen on spamrate.is — the plugin only reads your data and links out; it never changes your account. Read-only, and your data stays put The plugin is read-only — it tests your existing configuration but never modifies DNS records, email, or WordPress settings. It sends only the data you provide for a test, never your subscriber lists, content, or user data — and nothing contacts spamrate.is until you explicitly agree. Every call goes through this plugin's own server-side REST proxy, so your API token stays on the server and never reaches browser JavaScript; it's stored in your WordPress database, the same way any plugin stores its credentials.
