What does mailer mean?
A “mailer” can refer to several related things. Most commonly, it means a person, business, or service involved in sending mail. It may also denote a particular item sent by post, especially an advertisement, brochure, or other direct-mail piece designed for distribution to many recipients. In modern computing, the word can describe software or a system that sends electronic mail. The word is practical and versatile: a company might choose a direct-mail provider, prepare an advertising mailer, or select an email mailer for its communications. Because “mailer” can emphasize either the sender, the physical or electronic mailing item, or the mailing mechanism, the surrounding context usually determines which meaning is intended. In everyday North American usage, the promotional sense is especially familiar.
A person, organization, or device that sends mail, especially a business providing a mailing service.
"The mailer collected the completed forms and sent them to the processing center."
This sense is especially common in business and postal contexts.
A piece of mail intended for distribution, especially an advertisement or promotional communication.
"Customers received a colorful mailer advertising the store’s summer sale."
This sense is particularly common in North American commercial English.
A software application or system that sends electronic mail.
"The newsletter mailer sends the latest issue every Friday."
This is a technical or informal computing use.
Plural “mailers” can refer to multiple advertising pieces, mailing services, or electronic mail applications.
"The organization ordered thousands of mailers for its outreach campaign."
A mailer can mean either the business sending your advertisement or the advertisement itself—two very different things to meet in the mailbox.

Where does mailer come from?
The word “mailer” was formed in English by adding the suffix “-er” to “mail,” meaning something that sends, carries, or uses mail. “Mail” itself comes from Old English “mǣl,” an Old Norse-influenced term referring originally to a bag or packet and later to correspondence sent through the postal system. The derivative spread with the growth of postal services and, later, electronic communication.
