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).

• 18 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.

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. 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.

Nothing is sent anywhere until you explicitly agree. When you first open the

plugin, an onboarding screen explains the setup and waits for your

confirmation.

When you click “Agree & start free testing” (site setup):

– Your site URL, WordPress version, plugin version, and an anonymous

is, and a private installation

token is stored locally in your WordPress database. This is required to

provide the free daily test without an account. No inbound access to your

site is needed or requested.

– The installation identifier is a one-way hash derived from your site’s secret

keys (never the keys themselves). It lets your free daily quota survive a

plugin reinstall without tying it to your domain, and it is not reversible or

shared with anyone.

When you connect a SpamRate account (optional):

an email code, or Google) and confirm linking this site. Authentication

On return, an account token is stored locally in your WordPress database.

When you initiate a deliverability test:

– The sender address you specify and the test mailboxes you selected are sent

is, and the system waits for an email from that sender to those

mailboxes.

When you test a WooCommerce email (WooCommerce screen):

– The chosen email template is rendered with built-in sample data — never a

real customer’s order or personal data — and sent through your site’s own

mail pipeline to SpamRate’s test mailboxes at Gmail, Outlook, Yahoo and

other providers. Your store’s From address, the selected test mailboxes and a short

result can be matched to your test.

When you test a WordPress email (WordPress emails screen):

– A test message is sent through your site’s mail pipeline to SpamRate’s test

mailboxes. Your site’s From address, the selected test mailboxes and a

When you use a free DNS tool:

notifying you — until you pause or delete the monitor.
