Post SMTP

Maileroo provides seamless WordPress integration through the Post SMTP plugin, which now includes direct Email API integration. You can configure and send all outgoing emails via our Email API or traditional SMTP servers. This prevents your emails from landing in spam folders and ensures reliable delivery.

Key Features​

  • Email API Integration: Direct integration with Maileroo's Email API for seamless email delivery
  • SMTP Compatibility: Also supports traditional SMTP configuration with all major providers
  • Avoid Spam Folders: Boosts your email's chances of landing in the inbox, not spam
  • Easy Setup: No more confusing configurations - get started in minutes

Prerequisites​

Before setting up WordPress email integration, ensure you have:

  • Active Maileroo Account: You need a Maileroo account with Email API service enabled
  • WordPress Site: A WordPress site with admin access
  • Verified Domain: Your domain should be verified in Maileroo
  • Email API Credentials: API credentials created in your Maileroo dashboard
  • SMTP Account (Optional): Traditional SMTP credentials if you prefer SMTP over API delivery

Setup Instructions​

Step 1: Create Email API Credentials in Maileroo​

1.1 Navigate to Email API Service​

  1. Login to your Maileroo account and access the Email API service
  2. Click on 'Domains' in the left sidebar to access domain management

1.2 Access Domain Overview​

  1. Locate your domain in the domains list
  2. Click 'Overview' for the domain you wish to create API credentials for

1.3 Create Email API Credentials​

  1. Navigate to 'Sending Keys' in the new sidebar that appears
  2. Click 'New Sending Key +' in the top right corner
  3. Create a unique identifier (name) for this key (e.g., "WordPress Site - Production")
  4. You will now see an API key generated for you to start using
Security Note

If your API key gets compromised, simply create a new key by deleting the compromised key and generating a new one again. This ensures your email delivery remains secure.

Pro Tip

Choose a meaningful name for your API key like "WordPress Production" or "Main Website" to easily identify it later. You can create multiple keys for different environments (development, staging, production).

Then provide your username (the alias) and password generated when you created your SMTP credentials in your Maileroo account.

You are now configured to use Post SMTP with the SMTP delivery method.
