Why Your Verification Email Isn't Showing Up

A verification email that never shows up is almost always explained by one of a handful of causes. Work through these roughly in order.

The inbox expired

Temporary inboxes have a fixed lifetime. If enough time passed between creating the address and the site actually sending its message, the inbox may already be gone by the time the mail server tries to deliver it — at which point the message is rejected, not silently dropped somewhere retrievable. Create a fresh inbox and trigger the email again with less delay.

The site rejected the domain outright

Some sites maintain their own blocklists of known disposable-email domains and refuse the address at sign-up time, before ever attempting to send anything. If the sign-up form itself gave no error, this isn't what happened — but if it did, no amount of waiting will produce a message, because none was ever sent.

The sending service is slow, not broken

Transactional email is usually fast, but not instant — some providers queue and retry over several minutes, especially under load. Before assuming something failed, wait a few minutes and check whether the sending page mentions expected delivery time.

Detection found something you didn't expect

If a message arrived but no code or link is highlighted, the automatic detector may simply not have recognized the format — it's confidence-based and intentionally avoids guessing on ambiguous text rather than flagging something wrong with false certainty. Open the message and read the full body; the information is very likely there even when it isn't auto-highlighted.

It's genuinely a delivery problem on their end

Occasionally the issue really is on the sender's side — a misconfigured mail server, a suspended account, an outage. If a message never arrives after a reasonable wait and the domain wasn't rejected up front, that's the most likely remaining explanation, and there's nothing to troubleshoot on the receiving end.
