Not all envelopes are Post Office Preferred (POP) and therefore some attract a higher rate of postage. If the article is too small, too big or too thick to fit through their automatic sorting machinery, you get charged extra so it can be hand sorted. If in doubt, check with your local Australia Post office.

Don’t fall for the old ‘make my invitations now and find an envelope to fit later’ trick. Envelopes come in standard sizes so you need to find the envelope first and make your invitations to fit. Don’t forget to make the invite a bit smaller than the envelope (at least 5mm all sides) so that it slides easily in and out. Allow extra if the invite is bulky as the thickness will take up some of the width.
