Refresh the inbox
Ask MsgQuick for messages already received at the current address. This does not notify the sender or generate a new verification code.
DELIVERY LAB / 04
Verification email missing? Don’t keep clicking resend
Repeated requests may trigger the sender’s rate limits and cause old verification codes to arrive out of order. Follow the one-way diagnostic sequence below, changing only one variable at each step.
Six-minute diagnostic runway
Start by checking the address and finish with one resend. If a site explicitly rejects disposable email addresses, use an approved stable address instead of trying to bypass the restriction.
- 01
Check the address character by character
Compare the address in the registration form with the inbox address, paying close attention to the prefix, domain, and spaces left by autofill.
- 02
Wait one to two minutes
Sending queues can have brief delays. Keep the current page open while automatic syncing completes a few cycles.
- 03
Refresh once manually
Refreshing only reloads the current inbox; it does not request another verification code from the site.
- 04
Resend once from the site
Wait until the countdown or cooldown ends before resending, and use only the newest verification code that arrives.
Symptoms and most likely causes
| Symptom | Check first | Avoid | Next step |
|---|---|---|---|
| Inbox stays empty | Address spelling and site notices | Switching between multiple addresses | Wait, then refresh once manually |
| Multiple verification codes arrive together | Email arrival times | Trying the oldest code first | Use the newest verification code |
| The site says requests are too frequent | Cooldown countdown | Repeatedly refreshing and submitting the registration page | Wait for the restriction to lift |
| The site rejects the address | The sender’s email policy | Trying to bypass the restriction | Use an approved stable email address |
Keep “refresh” and “resend” separate
Resend from the site
Ask the sending site to create a new email. This may trigger a cooldown, replace an old code, or produce multiple delayed messages.
Change the address
Create a completely new receiving address. If the original site continues sending to the old address, the new inbox will not receive that message.
Extend the active period
Keep the current receiving address available longer when the sender has the correct address but the task is not yet complete.
Sending-side checks for developers
Envelope recipient
Confirm that the SMTP envelope recipient matches the address shown on the page; don’t check only the To header.
Response and retries
Record the sending service’s response code, queue ID, and retry time so you don’t mistake queuing for a delivery failure.
HTML and plain-text versions
Provide a readable text body, and check that the verification code, buttons, and domain remain clear after HTML sanitization.
RETRY WITH CONTROL
Keep the current address and try once more after a delay
Return to the inbox to check the countdown and address, then refresh first. Only go back and resend after confirming the site has not successfully sent the message.
