Run Your First Test

The test works with any email your WordPress site sends. You copy a unique test address from our homepage, send any email from your site to it, and we analyse exactly what a real inbox provider would see.

Step 1 — Get your test address

Go to the homepage. A unique address like test-a1b2c3@inbound.wpmailtester.com is generated for you automatically. Click Copy.

Each address is single-use and tied to your test. Don't reuse an old one — generate a fresh address for every test.

Step 2 — Send an email from your site to it

The important part: the email must come from your WordPress site, through its normal sending path — not from your Gmail. Any of these work:

Easiest: the WP Mail Tester plugin

Install our plugin and click one button — it handles the address and the send automatically, and shows results right in wp-admin.

From your SMTP plugin's test feature

  • WP Mail SMTP: WP Mail SMTP → Tools → Email Test → paste the test address → Send
  • FluentSMTP: FluentSMTP → Email Test → paste the address in "Send To" → Send Test Email
  • Post SMTP: Post SMTP → Actions → Send a Test Email
  • Easy WP SMTP / SMTP Mailer: each has a Test Email tab in its settings

From a contact form

Temporarily set your form's "send to" address (Contact Form 7 mail tab, WPForms notifications, etc.) to the test address, submit the form once, then change it back.

From WooCommerce

Place a test order using the test address as the customer email — the order confirmation email becomes your test. This is the most realistic test for stores, since it exercises the exact email your customers receive.

Step 3 — Watch for results

Back on our site, click the results button. The page updates automatically — most reports are ready 30–60 seconds after your site sends the email. If nothing arrives within a few minutes, see Test Email Never Arrived — that outcome is itself an important finding.
