As new terms become accepted by the mainstream they evolve into shorter words, single words and shed their capitalization and hyphenation. Words like “Web site” and “on-line” have over time have become “website” and “online” as people became more comfortable with them. “Electronic mail” has followed a similar acceptance arc, becoming “E-mail” and then “e-mail.”
It’s now time for “the word” to take its final step and become simply “email,” signifying the ubiquity of this form of communication, which is now used by 97% of all consumers and 94% of marketers, according to Forrester Research.
As a follower of the Email Experience Council I am a strong backer of the standardization of the spelling of email and I am planning to convert people to this spelling on client at a time.
