If your recipient prefers to keep things simple, they will receive an e-mail with a PDF document attached. An e-mail with a link to the document (with or without a login requirement) is another option.
If your recipient wants more, the e-mail can contain the PDF as well as a structured attachment. There are three standard formats, but other formats are also possible.
If your recipient has very high demands or can only receive files in one particular way, we can easily set up a solution for that too.
