Support

For anything not covered below, email support@nossletter.tech. Include the email address on your account, and if it's about a specific exercise, the exercise's URL (e.g. /learn/database-internals/b-tree) -- that's the fastest way for us to actually look at what you're seeing. We aim to reply within 2 business days.

Account access

Can't sign in? Use Log in and check the email/password you signed up with. If you signed up but never verified your email, resend the verification link from the sign up page's post-signup screen, or email us and we'll help directly.

There's no self-service "delete my account" button yet -- email support@nossletter.tech from the address on the account and we'll close it manually. See the cancellation policy for what that actually removes.

Billing and the Learn founding-member offer

Learn is a one-time payment, not a subscription -- see pricing for what it includes. For refund requests, see the refund policy. If a Stripe Checkout payment succeeded but your account still shows as locked, email us with the email address you paid with and roughly when the payment went through.

Something broken in an exercise

If a "run tests" result looks wrong -- your correct-looking solution fails, or a broken one passes -- tell us which exercise and paste what you submitted. That's a real bug report we want, not noise.

The daily digest / newsletter

There's no self-service unsubscribe link yet -- email support@nossletter.tech with the address the digest is going to and we'll remove you directly.
