Validate emails instantly, reduce bounce rates, and protect your sender reputation in real time — with a fully open-source code
Invalid and risky emails lead to bounce rates, spam flags, and wasted spend.
Invalid emails cause hard bounces, hurting sender reputation and deliverability scores.
Sending to risky addresses triggers spam traps and blacklists that are hard to escape.
Every invalid email is money spent on leads that will never convert or engage.
Users who can't receive emails drop off before activation, killing conversion.
Most verification tools are black boxes — you never know why an email passed or failed.
We believe in transparency, flexibility, and giving you complete control over your infrastructure.
