Fix · Forms and email

Email service rejects my "from" address

Not checked against the vendor's current screens

What you may see

It says the from address is not allowed or the domain is not verified
It only allows sending to my own address

Most likely cause

New email accounts often send only from a test address or to your own address until the sending domain is verified.

Check first (about two minutes)

Read the exact message: does it say test only, or domain not verified?

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.

The exact error or what you see

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 website forms and email sending, and explains them 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
New email accounts often send only from a test address or to your own address until the sending domain is verified.

DO THESE STEPS, IN THIS ORDER
1. Verify my sending domain in the service (see the authentication entry).
2. Change the "from" to an address on that verified domain, kept in one setting.
3. Keep a separate "reply-to" if replies should go elsewhere.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- A send from the verified address to an outside inbox works.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not use someone else's address as the sender.
- 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?

Steps

Verify my sending domain in the service (see the authentication entry).
Change the "from" to an address on that verified domain, kept in one setting.

Do not do this

Do not use a free-mail address (gmail or similar) as the sender of site mail.
Do not use someone else's address as the sender.

Fix it Email says "sent on behalf of" or fails sender checks
