OpenAI's conversational assistant, used through a browser or API account. AI products usually verify the address at sign-up before they let you use credits or an API key.
When you register, ChatGPT usually sends a verification code or link to the address you gave it. The sender, subject and exact wording are ChatGPT's own and can change, so look for a message that arrived right after you submitted the form.
Create the address first, paste it into the sign-up form, then keep this tab open: the verification mail normally lands within seconds.
Agents that evaluate or benchmark AI services often need a fresh account per run, which makes a throwaway inbox the natural fit.
With the Emailsify MCP server, an agent creates an address, fills in the ChatGPT form, then waits for the verification email. That wait returns only the extracted code or link, not the whole email, which keeps untrusted text away from the model. See how to connect your agent.
Use a temporary inbox when you only need to look around ChatGPT and you can afford to lose the account. Switch to an address you own if the account will hold anything you care about, if you need billing receipts, or if you may need a password reset.

That is ChatGPT's decision and it changes over time, so we cannot promise it. If ChatGPT rejects the address, do not try to disguise it. Use an address you control instead, especially for an account you want to keep.
Usually a few seconds after ChatGPT sends it. The delay is mostly on the sender's side. Keep the inbox open: it refreshes automatically, and ChatGPT codes and links are short-lived.
No. Mail is deleted 2 hours after it arrives and the address cannot be reclaimed, so a password reset later would go nowhere. Use a permanent address for any ChatGPT account you intend to keep.
Yes, on a Pro plan. The agent creates an inbox, submits the form, then waits for the code or link, which it receives the moment it arrives. Whether automating a ChatGPT sign-up is allowed depends on ChatGPT's terms.
