Check the address
Make sure everything before and after @ matches exactly, with no spaces, missing characters, or copied status text.
Delivery diagnostics
The code hasn’t arrived,
don’t keep clicking “Resend”
Each resend can invalidate the previous code. Check each step in the delivery path—it’s usually faster than repeatedly requesting another code.
Confirm the send action
The sender’s page should clearly show that the message was sent—not that validation failed or the countdown is still running.
Give the queue a moment
Delivery services may queue messages during busy periods. Wait one or two minutes, then manually refresh your inbox once.
Check sender restrictions
Some websites reject disposable domains, or may rate-limit requests made too frequently from the same device.
Use only the latest code
If you resend, the code in the older email will usually be invalid. Use the message with the most recent timestamp.
Try a different address
If the original address still shows nothing, start over with a new one—but don’t link important accounts to a temporary inbox.
Quick takeaway
Match the symptom to the next step
Handle waiting, rejection, and code errors differently instead of solving every situation with another resend.
No success message on the page
Return to the sender and correct the form or complete the verification challenge.
Just showed as sent
Wait a moment and refresh; don’t generate a second code immediately.
Multiple verification emails arrived
Choose the newest one by time; older codes are likely invalid.
