If your WordPress emails stopped working after the 6.9 update and you’re struggling to understand why, you’re in the right place to fix this issue step by step. Many site owners noticed contact form emails, WooCommerce notifications, password resets, and admin alerts failing or going to spam.

This step‑by‑step guide shows exactly how to fix WordPress email issues using SMTP, the most reliable solution recommended for WordPress 6.9 and beyond.

Why SMTP Is Mandatory After WordPress 6.9

WordPress 6.9 introduced stricter handling of the email envelope sender. As a result:

• PHP mail() is no longer reliable
• Emails without authentication fail silently
• Gmail, Outlook, and Yahoo block unauthenticated senders

SMTP fixes all of this by authenticating emails before sending.

Step 1: Choose a Reliable SMTP Plugin

For WordPress 6.9, these plugins work best:

• WP Mail SMTP (Beginner‑friendly)
• FluentSMTP (Free & powerful)
• Post SMTP Mailer (Advanced logging)

Recommended for most sites: WP Mail SMTP

Step 2: Install WP Mail SMTP Plugin

1. Go to WordPress Dashboard → Plugins → Add New
2. Search for WP Mail SMTP
3. Click Install → Activate

Once activated, you’ll see the WP Mail SMTP Setup Wizard.

Step 3: Choose Your SMTP Mailer

WP Mail SMTP supports multiple mailers. Popular options:

For beginners, choose Gmail or Brevo.

Step 4: Configure SMTP Settings (Example: Other SMTP)

If you select Other SMTP, enter:

• SMTP Host: yourmailprovider.com
• Encryption: TLS
• SMTP Port: 587
• Authentication: ON
• Username: your email address
• Password: email app password

Enable Force From Email Enable Force From Name

Step 5: Fix the “From Email Address” Issue (Very Important)

After WordPress 6.9, emails sent from:

[email protected]

are often rejected.

Best Practice:

• Use a real domain email like:
  • [email protected]
  • [email protected]

Make sure this email exists in your hosting or SMTP provider.

Step 6: Send a Test Email

1. Go to WP Mail SMTP → Tools → Email Test
2. Enter your email address
3. Click Send Email

If successful, WordPress email issues are fixed If failed, continue to DNS setup below

Step 7: Add SPF, DKIM & DMARC Records (Critical for Deliverability)

Without DNS authentication, emails may still land in spam.

Required DNS Records:

SPF (Example)

v=spf1 include:_spf.google.com ~all

DKIM

Provided by your SMTP provider (copy exactly)

DMARC (Basic Setup)

v=DMARC1; p=none; rua=mailto:[email protected]

Add these in Domain DNS Manager (GoDaddy, Namecheap, Cloudflare, etc.)

Step 8: Fix Contact Form & WooCommerce Emails

Contact Forms (CF7 / Elementor / WPForms)

• Set From Email to same SMTP email
• Avoid user‑entered emails as sender

WooCommerce

Go to: WooCommerce → Settings → Emails

• Enable email notifications
• Ensure “From email” matches SMTP email

Step 9: Enable Email Logging (Optional but Recommended)

WP Mail SMTP Pro includes email logs.

Free alternatives: – WP Mail Logging – FluentSMTP logs

This helps track: – Failed emails – SMTP errors – Delivery status

Common Errors & Fixes After WordPress 6.9

SMTP Authentication Failed

• Check username/password
• Use app password (Gmail)

Emails Go to Spam

• Add SPF, DKIM, DMARC
• Avoid free Gmail as sender

Emails Not Sending at All

• Disable other SMTP plugins

Final Checklist (WordPress 6.9 Email Fix)

Introduction: The Scaling Dilemma Every Agency Faces

If you run a web or SEO agency, you’ve probably been here before —
too many client projects, not enough developers, and an inbox full of “when will my site go live?” messages.
We get it. Agencies grow fast, and web development capacity often struggles to keep up. But hiring full-time developers isn’t always the answer — it’s expensive, unpredictable, and hard to scale without sacrificing profit margins.
That’s exactly where a white-label WordPress partner comes in — especially one who lives and breathes Elementor.

What’s Changing in 2026

2026 is shaping up to be the year of agency specialization.
Most agencies are niching down, focusing on SEO, paid media, or design — not on the tech-heavy parts of WordPress builds.
At the same time, client expectations are higher than ever:

• “Can you deliver it by next week?”
• “Can you make it faster on mobile?”
• “Can you integrate this with our CRM and optimize for SEO?”

Agencies that can say yes confidently to those requests — without stretching their team — are the ones that’ll win.

Why White Label Partnerships Make Sense (Now More Than Ever)

Here’s the truth: agencies that scale sustainably all have one thing in common — they know what to keep in-house and what to delegate.
When you partner with a white-label WordPress team like ours, you instantly:

1. Expand your team capacity without hiring.
2. We become your development wing — working behind the scenes, branded as you.
3. Deliver faster using Elementor workflows optimized for agencies.
4. We use pre-built kits, reusable widgets, and automation to cut build times.
5. Keep your margins healthy.
6. No surprise payroll costs. No office overhead. Just predictable, per-project pricing.
7. Protect your client relationships.
8. We work under strict NDAs — your clients will only ever see your brand.

Real-World Example

One of our agency partners in New York came to us after burning through three in-house developers in a year.
They were great at SEO and client management — but every WordPress project slowed them down.
We set up a white-label collaboration:

• Shared Slack channel
• Trello for project management
• Standardized Elementor templates

In the first quarter, they delivered 12 websites instead of 5. Their profit margins grew by 38%, and client satisfaction scores hit a record high.
That’s not a one-off. We see this story play out every month with agencies across the U.S.

The Hidden Advantage: Strategic Focus

Outsourcing your builds doesn’t just save time — it frees up focus.
When your team isn’t bogged down in revisions and debugging, they can double down on client strategy, retention, and upselling — the real growth drivers.
A white-label partner becomes your invisible engine — running smoothly in the background while you lead the brand forward.

Why Agencies Choose TechnoCrackers

We’ve built over 300+ WordPress and Elementor websites as a silent partner for agencies.
Our secret sauce? Reliability + speed + communication.

• Dedicated Slack channels for every agency
• Elementor Pro expertise for rapid, high-quality builds
• SEO-friendly site structures from day one
• White-label reporting and project documentation

When we say we’re your team — we mean it.

Creating custom product tabs in WooCommerce using Advanced Custom Fields (ACF) allows store owners to display additional product information in a clean, organized, and user-friendly way. Instead of hardcoding content, ACF enables you to manage tab titles, content, and order directly from the WordPress admin panel, making it easy to create unlimited, product-specific tabs without touching code repeatedly.

Step 1: Install Required Plugins

Make sure these plugins are active:

• WooCommerce
• Advanced Custom Fields (ACF) (Free or Pro)

Step 2: Create ACF Fields

Option A: Single Custom Tab

1. Go to ACF → Field Groups → Add New
2. Field Group Title: Product Custom Tabs
3. Add Fields:
   • Tab Title
     • Field Type: Text
     • Field Name: tab_title
   • Tab Content
     • Field Type: WYSIWYG Editor
     • Field Name: tab_content

4. Location Rule:
   • Post Type → is equal to → Product
5. Publish the field group

Option B: Multiple Tabs (Recommended – ACF Repeater)

1. Add a field:
   • Field Type: Repeater
   • Field Label: Product Tabs
   • Field Name: product_tabs
2. Inside the repeater, add sub-fields:
   • Tab Title
     • Type: Text
     • Name: tab_title
   • Tab Content
     • Type: WYSIWYG
     • Name: tab_content
   • Tab Priority (Optional)
     • Type: Number
     • Name: tab_priority

3. Location Rule:
   • Post Type → is equal to → Product
4. Publish

Step 3: Add PHP Code to Display ACF Tabs

Add this code to your child theme functions.php or a custom plugin.

add_filter( 'woocommerce_product_tabs', 'acf_product_tabs' );
function acf_product_tabs( $tabs ) {
    if ( have_rows( 'product_tabs' ) ) {
        $i = 1;
        while ( have_rows( 'product_tabs' ) ) {
            the_row();
            $title    = get_sub_field( 'tab_title' );
            $priority = get_sub_field( 'tab_priority' ) ?: (50 + $i);
            if ( $title ) {
                $tabs['acf_tab_' . $i] = array(
                    'title'    => esc_html( $title ),
                    'priority' => intval( $priority ),
                    'callback' => function() use ( $i ) {
                        acf_product_tab_content( $i );
                    }
                );
            }
            $i++;
        }
    }
    return $tabs;
}

Step 4: Add Callback Function for Tab Content

function acf_product_tab_content( $index ) {
    if ( have_rows( 'product_tabs' ) ) {
        $i = 1;
        while ( have_rows( 'product_tabs' ) ) {
            the_row();
            if ( $i === $index ) {
                echo '<div class="acf-product-tab-content">';
                the_sub_field( 'tab_content' );
                echo '</div>';
                break;
            }
            $i++;
        }
    }
}

Step 5: Add Tabs from Product Edit Screen

1. Edit any WooCommerce product
2. Scroll to Product Tabs section
3. Click Add Row
4. Enter:
   • Tab Title
   • Tab Content
   • Optional Priority
5. Update the product

Tabs now appear automatically on the frontend.

Final Thoughts

Creating custom product tabs in WooCommerce using Advanced Custom Fields (ACF) is a powerful and flexible way to manage detailed product information without hardcoding content. By leveraging ACF repeater fields and WooCommerce hooks, you can add unlimited, product-specific tabs that are easy to maintain directly from the WordPress admin panel.

This approach improves content organization, enhances the user experience, and allows non-technical users to update product details effortlessly. Whether you’re adding FAQs, specifications, warranty information, or size guides, ACF-based product tabs provide a scalable solution that works seamlessly with any WooCommerce theme or page builder.

By implementing this method, you gain full control over tab structure, content, and display logic—making it an ideal choice for modern, content-rich WooCommerce stores.
