Email rate limit exceeded when signing up

Not checked against the vendor's current screens

What you may see

Sign-up works a few times then says email rate limit exceeded
I am testing sign-up many times

Most likely cause

The built-in email sender allows only a few emails per hour, and test sign-ups use them up.

Check first (about two minutes)

Count how many test sign-ups you did in the last hour.

The fix prompt

What you type here never leaves your browser. The search runs on this page, and nothing is sent to a server or to an AI.

What you did before it happened

Kept only in this browser, on this device. Keys and passwords are removed before anything is saved.

Prompt language

You are a careful senior engineer who knows Supabase (database, login and file storage) and explains it to people who are not developers. I am not a developer, so explain every step in plain words and tell me exactly which button, menu or command you mean. If you are not sure about something, say so; do not guess.

Menu and button names change over time. If you cannot find a button or page I mention, say so and tell me what to look for instead of guessing.

MOST LIKELY CAUSE
The built-in email sender allows only a few emails per hour, and test sign-ups use them up.

DO THESE STEPS, IN THIS ORDER
1. Explain the sending limits in my project (read them in the project's authentication settings; they change) and when they reset.
2. For testing, use a few test accounts and wait, or add test users from the dashboard.
3. For real use, set up my own email sending service (SMTP) with a verified domain.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- Sign-up emails arrive without limit errors during normal use.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not remove the rate limit message from the page; show a calm explanation.
- Anything I did not ask about: the design, the text, other pages, other settings or the data.
- Do not delete files, data or branches, do not reset or force-push, and do not rewrite history, unless you first show me exactly what would be lost and I say yes.
- Do not paste, print or ask me to paste a password or secret key into this chat. If one is needed, tell me which settings page of the right service to store it in.

WHEN YOU FINISH
Explain in simple words what you changed (file by file or setting by setting), why you changed it, and how I can undo it.

Paste it into Claude, ChatGPT, Gemini or Cursor, then follow what it says.

After you tried it, did it work?
