Was butted mail used

You meant "buttered mail"!

Buttered mail, also known as "buttered letters" or "buttered correspondence," was a practice used in the past, particularly during the 18th and 19th centuries. It was a way to add a touch of luxury and elegance to written communication.

In this practice, a small amount of butter or other edible fat (such as lard or tallow) was applied to the edges of a letter or package before sealing it with wax or sealing wax. The butter or fat would help to prevent the wax from sticking to the paper or other surfaces, making it easier to open and close the letter or package.

Buttered mail was often used for important or formal correspondence, such as business letters, diplomatic communications, or love letters. It was also used to send valuable or fragile items, like artwork or jewelry, to ensure they arrived safely.

The practice of buttered mail was popular in Europe, particularly in England, France, and Germany, during the 18th and 19th centuries. However, it eventually fell out of favor as more efficient and practical methods of sealing and protecting mail were developed.

Today, buttered mail is mostly a curiosity, and it's no longer a common practice. However, it's still an interesting piece of history that gives us a glimpse into the ways people used to communicate and send mail in the past.
