Building NoParam: A Privacy-First Email Validation API (Waitlist Open!)
Hey Indie Hackers! 👋
I’m building NoParam, a privacy-focused email validation API for marketers, SaaS founders, and developers.
Most email validation tools collect and resell user data. I wanted something privacy-first that integrates seamlessly into any stack and just works.
How NoParam Stands Out
✅ Real-time & bulk validation
✅ No tracking, no reselling user data
✅ Lightweight & fast API
✅ Mailchimp & HubSpot integrations coming soon
I’m launching soon and looking for early adopters & feedback. If this sounds useful, join the waitlist here: noparam.com
Would love to hear—what’s your biggest pain point with email validation?

This is a useful angle. My main pain point with email validation is trust, not syntax: I want to know exactly what gets sent to the validator, how long it is retained, and whether the address ever becomes part of a secondary dataset.
If I were evaluating this as a founder, the decision page I’d want is: what do you check in real time, what do you never store, what logs exist for abuse/debugging, and how integrations avoid quietly becoming another marketing-data sink.
“Email validation without turning the list into a data product” is a clear positioning lane if you can make the data-handling details concrete.
How would you compare this to Abstract API?
Abstract API provides email validation along with other APIs, while NoParam is built specifically for email validation with a strong focus on privacy. Unlike many validation tools, NoParam doesn’t store or resell data—it’s a privacy-first solution.
Also, we’re working on deep integrations with platforms like Mailchimp, HubSpot, WordPress and more to make validation seamless for marketers and businesses.
If you’ve used Abstract API, I’d love to hear what you liked/disliked about it! Always open to feedback.
