カンボジアの電子ビザ支払い確認メールが届かない？米国旅行者の解決策

Where the confirmation email is actually hiding

Once you have confirmed the payment landed, the receipt is almost certainly sitting in your mailbox somewhere — just not in the inbox where you expected it. Email providers route automated transactional messages aggressively, and a confirmation from a travel-document sender you have never emailed before is exactly the kind of thing Gmail, Outlook, and Apple Mail like to tuck away. Work through these spots in order and you will find it the vast majority of the time.

Start with the spam and junk folder. This is where the receipt lands more often than anywhere else, because the message arrives from an unfamiliar sender, contains a dollar amount, and carries an attachment — three things spam filters treat as suspicious by default. In Gmail, also check the Promotions and Updates tabs, which quietly siphon off transactional email that never appears in the Primary tab. On Outlook, look in the Other inbox if you have Focused Inbox switched on, and in the Junk Email folder.

The most reliable move is to search your whole mailbox rather than scroll folder by folder. Search across all folders at once for the dollar amount — "$80" or "$90" — and separately for words like "Cambodia," "eVisa," "visa," "payment," or "receipt." Searching the amount is the trick most people skip, and it usually surfaces the message instantly even when it has been filed somewhere odd. If you use email rules or filters, check whether one of them auto-archived or auto-deleted the message based on a keyword before you ever saw it.

Give it a little time, too. Transactional email is usually near-instant, but during a busy travel period or right after a Cambodian public holiday the receipt can lag by minutes to a couple of hours, and your provider may batch-deliver it. If you confirmed the charge on your statement, the receipt is coming — checking again in an hour often resolves it on its own. While you wait, you can confirm the application is moving by checking the status directly; our guide on how to check your Cambodia eVisa status shows US travelers exactly where to look.

The two real reasons an email never arrives

If you have confirmed the payment, searched every folder, and waited an hour with still nothing, then you are in the small minority where the email genuinely is not reaching you. There are really only two causes worth your attention, and both are easy to identify and fix. Neither one affects whether your visa gets approved — they only affect whether the receipt can physically land in front of you.

A typo in the email address you typed at checkout

This is by far the most common reason a confirmation email never shows up. One transposed letter, a missing dot, a .con instead of .com, or "gmial" instead of "gmail" sends the receipt to an address that does not exist or belongs to a stranger. You typed the address quickly during checkout, the system trusted what you entered, and the message bounced or vanished into the wrong mailbox. There is nothing wrong with your application — the email simply has nowhere valid to go. The fix is to have support correct the address on file and re-send, which we cover in the next section.

A corporate or locked-down work inbox

If you used your work email, your company mail server may be silently quarantining the message. Corporate IT systems are tuned to block or hold inbound email from unfamiliar external senders, especially anything carrying a PDF attachment, which is precisely what a visa confirmation and the later approval PDF both are. The receipt may be sitting in an administrator-controlled quarantine you cannot even see, with no notification to you. This is why a personal Gmail, Outlook, or iCloud address is always the safer choice for a visa application — those inboxes accept outside transactional mail without an IT layer in the way.

How to get the receipt re-sent — and what you actually need

When the email genuinely is not reaching you, the fix is straightforward: you do not start over and you do not pay again. You get the existing message re-sent to a working address. Because your payment already went through and your application is already in the queue, nothing about the visa needs to change — only the delivery address for the email.

Reach out to US-timezone support with the basics that let them find your file fast: the name exactly as it appears on your passport, the date you applied, the last four digits of the card you paid with, and the dollar amount charged. They can locate the application, correct a mistyped email address, and re-send the confirmation — and later the approved PDF — to a personal inbox that will actually receive it. You do not need to verify the visa itself is moving before they help; sorting the email out and confirming the application state can happen on the same call.

It helps to keep the two emails clear in your head while you do this. The payment confirmation is the receipt — proof you paid and that the application is in the queue, and the document you may need later if you are claiming the visa back on an expense report. The approval email is the one that carries your printable eVisa PDF, and it arrives within 3 business days of a clean application. If the receipt was misfiled or bounced, the approval email can still arrive perfectly well at the same address, so fixing the delivery address now means both messages reach you. You bring the PDF to the airport, not the receipt — so the receipt missing is an inconvenience, never a trip-stopper.

Once the address is corrected, the approved eVisa is delivered as a printable PDF by email within 3 business days, with free resubmission if Immigration flags a correction and US-timezone support on the same channel throughout. If you want a clear sense of when that approval message should land versus the receipt, our guide on when your Cambodia eVisa arrives by email lays out the full delivery timeline for US travelers.

There is one more small message to keep on your radar. Every air arrival in 2026 also files the Cambodia e-Arrival Card, a separate digital declaration verified through us — 14 fields covering your passport, flight, and accommodation, submitted within 7 days before you land. It generates its own confirmation, separate from the visa receipt, so if you have paid the $5 USD e-Arrival fee, look for that confirmation independently and apply the same inbox checks. Keeping the visa receipt, the approval PDF, and the e-Arrival confirmation mentally separate stops one missing email from feeling like all three went wrong.
