Email has been around for longer than the web itself.
I remember sending my first emails way back in the late 1980s.
Funny thing though. Online pundits keep telling us how email is going to disappear. Eaten by the web, made obsolete by texting, made irrelevant by messaging apps.
And yet… email is still going strong.
More amazing still, it still functions in pretty much the exact same way as when the SMTP, POP3 and IMAP protocols were formalized back in 1995.
Everything else online changes at warp speed… but email and its functionality remains the same.
No wonder marketers love it. It’s easy, and familiar.
