Spend $0 to clean your email list 💌

Hi!

If you're sending marketing or cold emails, you will love this email validator – https://sidemail.io/tools/email-validator/

Nothing ruins a campaign like poor deliverability. Bad email addresses drive up bounces, hurt your sender reputation, and lower open/reply rates.

Email validator is what helps you avoid this.

But most of the tools like this hide behind signups and paywalls.

I wanted a no-signup, in-browser checker you can use fast. So I built it, and you can use it too.

It’s free and online.
