We’re thrilled to announce the launch of our very first WooCommerce extension: Kickbox Email Verification for WooCommerce! 🎉
If you’re running an online store, you know how critical customer email addresses are. They’re the gateway to order confirmations, shipping updates, marketing campaigns, and customer communication. But here’s the harsh reality: every invalid email address in your database costs you money.
The Hidden Cost of Invalid Emails
Think about it—when a customer enters a fake or invalid email address at checkout, you’re not just losing contact with that customer. You’re also:
- Wasting marketing dollars sending emails to addresses that will never be delivered
- Damaging your sender reputation with high bounce rates
- Missing critical communications like order confirmations and shipping notifications
- Losing potential repeat customers who never receive your follow-up emails
- Spending hours manually cleaning your email lists
The problem compounds over time. A few invalid emails here and there might not seem like a big deal, but when you’re processing hundreds or thousands of orders, those bad addresses add up fast—and so do the costs.
Stop the Problem at the Source
That’s exactly why we built the Kickbox Email Verification for WooCommerce plugin. Instead of discovering invalid emails weeks later through bounce notifications, you can now catch them in real-time, right at checkout.
How It Works
The integration is beautifully simple:
- Customer enters their email during checkout or account registration
- The plugin verifies the email instantly with Kickbox’s powerful API (typically in under 2 seconds!)
- Based on the verification result, the customer is either allowed to proceed, blocked, or allowed with a flag for your review
It’s that straightforward. No complicated setup, no manual intervention needed—just seamless protection that works behind the scenes to keep your customer database clean.
Real-Time Protection Where It Matters Most
Checkout Verification
The plugin integrates seamlessly with your WooCommerce checkout process, verifying email addresses as customers enter them. Whether they’re using the classic checkout or the modern WooCommerce Blocks checkout, the verification happens automatically and asynchronously—meaning it won’t slow down your checkout process.
Account Registration Protection
New customer registrations are also protected. When someone creates an account on your store, their email is verified before the account is created, ensuring you only collect valid contact information from day one.
Flexible Configuration for Your Business Needs
We understand that every store is different, which is why we’ve built in flexible action configuration. For each type of verification result, you can choose what happens:
- Deliverable emails (confirmed valid) → Allow checkout
- Undeliverable emails (confirmed invalid) → Block checkout, or flag for review
- Risky emails (suspicious but not definitively invalid) → Your choice: allow, block, or flag
- Unknown emails (couldn’t be verified) → Your choice: allow, block, or flag
This flexibility means you can tailor the plugin to match your risk tolerance and business model. Want to be strict? Block all undeliverable emails. Prefer to review edge cases? Flag risky emails and make decisions manually. It’s completely up to you.
Powerful Admin Tools
Comprehensive Analytics Dashboard
The plugin includes a beautiful analytics dashboard that gives you insights into your email verification data. You’ll see:
- Total verification counts by result type
- Visual pie charts showing result distribution
- Detailed breakdowns of verification reasons
- A convenient dashboard widget for quick stats
This data helps you understand patterns, identify potential issues, and make informed decisions about your verification settings.
Flagged Emails Management
When emails are flagged for review, you get a dedicated management interface where you can:
- Review detailed verification information for each flagged email
- Make bulk decisions (allow or block) on multiple emails at once
- Add notes about your decisions for team reference
- See which emails came from checkout vs. registration
- Link flagged emails to their associated orders
Once you make a decision on a flagged email, the plugin remembers it. If that same email address is used again, your decision is automatically applied—saving you time and Kickbox API credits.
Cost and Time Savings for Store Owners
Let’s talk numbers. Here’s what the Kickbox Integration can save you:
Marketing Cost Savings
If you’re sending 10,000 marketing emails per month and 5% are invalid (a conservative estimate), that’s 500 wasted emails. At typical email marketing costs, you could be saving hundreds of dollars per month by catching these before they enter your database.
Time Savings
Manually cleaning email lists is tedious and time-consuming. With automated verification, you’re saving hours every month that you can spend on growing your business instead of maintaining your database.
Reduced Cart Abandonment
By catching invalid emails before checkout completion, you’re also reducing cart abandonment. Customers with invalid emails often abandon carts when they realize they won’t receive order confirmations. Real-time verification helps them correct their email address before it’s too late.
Improved Deliverability
A clean email list means better sender reputation, which means better inbox placement for all your emails. This translates to higher open rates and more sales from your marketing campaigns.
Developer-Friendly Features
Built with modern web technologies, the plugin features:
- React-powered admin interface for a smooth, responsive experience
- Sandbox mode for testing without using Kickbox credits
- Comprehensive error handling that won’t break your checkout if the API is temporarily unavailable
- WordPress and WooCommerce best practices throughout
