Can I travel to Vietnam without the visa letter and get it upon arrival at Vietnam airport
NO.
In case you intend to get a visa on arrival for Vietnam at Vietnam airport, the most important that you need to show at your departure airport and also at Vietnam airport to get visa stamped is the VISA APPROVAL LETTER. Without it, you cannot get on board, not to say getting visa.
It’s very simple to get an approval letter for Vietnam visa. You can see how to get it here.
Please note that there are two types of the visa approval letter: group/shared one and private/confidential one. With the former, your letter may contain names of other travelers unknown to you, while with the latter, your letter contains details of you/your group only.
