Building Remindr — automated invoice follow-ups for freelancers. Would love feedback.

Body: Hey Product Hunt — first time posting here.

I'm building Remindr, a lightweight tool that connects to Stripe and automatically sends polite escalating reminder emails to late-paying clients until payment lands — then stops immediately.

No new invoicing workflow. Just a follow-up layer on top of what freelancers already use.

I validated the idea before writing any code — put up a landing page to test interest first.

Would love to hear from anyone who's dealt with this problem:

• Is this something you'd actually pay for?

• Is $19–49/mo the right pricing range?

• Anyone already solving this that I should know about?

Happy to answer any questions!
