THE INDUSTRY’S FASTEST EMAIL VALIDATION API TOOL
Maximize email efficiency and drive revenue
One bad email address can damage your email program - multiply that by tens, hundreds, or thousands and you will see a drop in inbox placement, engagement, and overall email ROI (maybe even land on a blocklist).
Integrate the industry’s fastest email validation API directly into your platform to systematically remove invalid and high-risk email addresses in real time, leveraging Mailgun’s technology to instantly identify disposable addresses.
PROTECT YOUR EMAIL SENDER REPUTATION
Remove disposable email addresses and minimize risk
Bad actors are working tirelessly to find new ways to manipulate your systems and create new (illegal) opportunities for themselves. And now that disposable email addresses are widely available, it makes organic email list building that much harder for legitimate senders.
Our email validation API is able to identify most types of disposable addresses, so you have one less thing to worry about when building your email lists the right way.
