Stamp Categories: What Type of Stamp Does Your Email Need?

Stamps are a bit confusing, so here are the basics: it costs a certain amount of money to mail something, depending on the package weight and delivery method (First Class, Priority, etc.). You can pay the fee for going to the post office and paying the exact amount that is owed for that particular package – or you can simply use stamps to meet the required amount of shipping charges.

Stamps are just one way to pay shipping costs; however, as much as you paid for the stamp the amount of the shipping charges covers (with the possible exception of Forever stamps – we’ll get to that in a moment). To the question of how many stamps is needed is essentially asking for the cost of shipping the package, in terms of the available designations of the stamps.

Because knowing the weight of your email is often crucial to the correct postage placement, the bottom line is that you may be best off just going to the post office if you’re not sure how much of your package or what it weighs. . Guessing the correct amount of shipping costs is difficult. However, there are basic rates for different types of mail that will guide you in estimating an exact amount.

How many stamps go in a letter?

Estimate the cost of shipping costs

For an occasional piece or piece of mail, it may be worth it simply to estimate the shipping cost and add the required number of stamps, keeping in mind that you will lose the cost of any excess postage (think of it as paying the fare on a bus; you have to meet the minimum cost with any of the denominations you have available, but you will not get any change).
