ZeroBounce + Cloudflare Workers email address validation
Cloudflare Worker-based email validation with the ZeroBounce Email Validator
The ZeroBounce email validator now officially integrates with Cloudflare Workers to assist with email list cleaning. Through Cloudflare Worker’s super-computing platform Edge, you can integrate with ZeroBounce’s real-time email validation to prevent bounced emails and spam complaints while improving your email deliverability in real time.
How Cloudflare Worker’s email validation middleware works
The Cloudflare worker intercepts any incoming POST requests on the route where it’s deployed. In other words, it examines any email address entered into your website form, validates it, and rejects or accepts the address based on the results.
The integration currently allows for
✓ AJAX email validation
Note - JSON email validation is not yet supported and may arrive in a future update.
You can easily set up your email validation middleware by
- Creating Cloudflare Workers KV storage for your validation logs
- Creating the worker
- Establishing variables for your ZeroBounce API key, timeout rules, and email validation status
- Add a binding to store your logs
- Set up the route for your Cloudflare worker

Benefits of using Cloudflare Worker-based email validation
Automate your email list cleaning
The best way to keep your email list filled with healthy, valid contacts is by blocking the bad data from your list automatically.
With a few easy installation steps, you can integrate the ZeroBounce email validator on any websites for better email list hygiene.
Say goodbye to invalid contacts and other bad actors that can quickly sabotage your email marketing metrics and email deliverability.
Eliminate bounced emails
Every time you email an invalid address, the message bounces back. A bounce rate higher than 2% can cause ISPs to raise an eyebrow.
The higher your bounce rate, the more likely your emails will end up in a spam folder or bounce altogether. If you aren’t hitting the inbox, you aren’t getting the ideal return on investment (ROI) from your email marketing.
Help keep your number of bounced emails low by using Cloudflare Worker-based email validation on your website registration forms.
Protect your email reputation
High bounce rates, low engagement, and high spam complaints can tarnish your email sender reputation. ISPs can’t risk delivering untrustworthy content to their users.
People with a low sender score struggle to hit the inbox. No matter how great your emails are, they’ll likely hit spam or bounce back due to a poor email reputation. If your reputation continues to decline, your email provider may suspend your account, and ISPs may begin to blacklist your domain.
Don’t risk your email reputation over invalid addresses. Install the email verification integration now to protect your email list automatically.
