WordPress (SMTP)
Route WordPress email through MailBlastr over SMTP with the WP Mail SMTP plugin.
WordPress sends mail through PHP's wp_mail() by default, which is unreliable. Route it through MailBlastr over SMTP using the WP Mail SMTP plugin so every site email — password resets, form notifications, WooCommerce receipts — is delivered and tracked in your MailBlastr dashboard.
Prerequisites
- A MailBlastr API key.
- A verified domain to send from.
1. Install a plugin
Install and activate the WP Mail SMTP plugin. When the setup wizard appears you can skip it — click Go to the Dashboard at the bottom of the screen — and we'll configure the plugin manually below.
2. Configuration
From your admin dashboard, open WP Mail SMTP > Settings. First set your From Email (an address on your verified domain), From Name, and Return Path. Then, in the Mailer section, select Other SMTP.
In the Other SMTP section, configure the following settings:
| Setting | Value |
|---|---|
| SMTP Host | smtp.mailblastr.com |
| Encryption | SSL |
| SMTP Port | 465 |
| Auto TLS | ON |
| Authentication | ON |
| SMTP Username | mailblastr |
| SMTP Password | Your API key, e.g. mb_xxxxxxxxx |
TLS and SMTP Port to 587. Replace the password with an existing API key or create a new one on the API keys page.3. Send a test email
Open WP Mail SMTP > Tools and send a test email to confirm the integration works. A successful send appears in your MailBlastr emails dashboard.
