Automate Email Newsletters from Blog Posts Using WordPress & PHP

ByBrian Bateman

— Automating email newsletters can significantly enhance content delivery and audience engagement, saving time and effort for businesses. In this guide, you’ll learn how to efficiently pull blog posts from WordPress and transform them into automated email newsletters using PHP, boosting your marketing performance through seamless automation.

Understanding the Basics

By automating newsletters, you ensure readers receive timely updates without manual intervention. This is crucial for maintaining audience engagement and leveraging content efficiently. We’ll use WordPress REST API and PHP scripting to automate this process.

Key components include:

  • WordPress REST API: Fetches blog post data.
  • PHP Scripts: Processes and formats the data into an email.
  • SMTPServer: For sending emails automatically.

Setting Up WordPress for Automation

Ensure your WordPress site is ready to share data via API:

  1. Enable REST API: WordPress typically has this enabled by default. Verify with your hosting provider if you experience issues.
  2. Permalinks Settings: Go to Settings > Permalinks and ensure they’re not set to plain.
  3. Install Necessary Plugins:
    • WP Mail SMTP: To configure SMTP settings for sending emails.
    • WP-Crontrol: Manage cron events that schedule tasks.

Writing the PHP Script

Create a PHP script to automate the newsletter generation:

  1. Fetch Posts:

    $response = wp_remote_get('https://yourwebsite.com/wp-json/wp/v2/posts');
$posts = json_decode(wp_remote_retrieve_body($response));

  2. Format the Email:

    foreach ($posts as $post) {
   $content .= "{$post->title->rendered}";
   $content .= "{$post->excerpt->rendered}";
}
  3. Send the Email: 
    $to = 'su********@*****le.com';
$subject = 'Latest Blog Posts';
$headers = ['Content-Type: text/html; charset=UTF-8'];
wp_mail($to, $subject, $content, $headers);

Scheduling with Cron Jobs

Leverage cron jobs to run the PHP script automatically:

  1. wp-cron: Use WP-Crontrol to schedule your tasks.
  2. System Cron Jobs: Add a cron job on your server: 
    0 8 * * * /usr/bin/php /path-to-your-script.php

    This runs the script every day at 8 AM.

FAQ Section

How do I secure my REST API endpoints?

Use authentication methods like OAuth or API keys to restrict access.

Can this method handle a large number of subscribers?

Yes, but ensure your server can handle the load and consider a scalable SMTP solution.

What if a post update fails to send?

Implement error handling in your script to log and retry failed attempts.

Can I customize the email template?

Absolutely, use HTML/CSS within the PHP script to design the email layout as needed.
