A language-learning app. Content platforms verify the address before they unlock a free tier, a download or a subscription.
When you register, Duolingo usually sends a verification link to the address you gave it. The sender, subject and exact wording are Duolingo's own and can change, so look for a message that arrived right after you submitted the form.
Progress is saved to the account, so a temporary address is only for a quick try.
Research agents gather gated material and need a verification step they can complete without a human inbox.
With the Emailsify MCP server, an agent creates an address, fills in the Duolingo form, then waits for the verification email. That wait returns only the extracted 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 Duolingo 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 Duolingo's decision and it changes over time, so we cannot promise it. If Duolingo 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 Duolingo sends it. The delay is mostly on the sender's side. Keep the inbox open: it refreshes automatically, and Duolingo 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 Duolingo account you intend to keep.
Yes, on a Pro plan. The agent creates an inbox, submits the form, then waits for the link, which it receives the moment it arrives. Whether automating a Duolingo sign-up is allowed depends on Duolingo's terms.
