So I’ve had a discussion these days with a colleague from work about a client that requested us to code a "text-only" email. From what I’ve done so far, you use text-only mails for cases where an e-mail client disabled the rendering of html, to assure that these people still get the message. so my understanding was that plain text e-mails do not contain ANY HTML at all.
My colleague then corrected me and told me that e-mails ALWAYS contain HTML, also text-only e-mails. Interestingly, it’s very hard to find a source online which explains the presence / absence differences of HTML in plain text vs normal HTML e-mails. So I was wondering, do plain text mails actually indeed contain HTML?
>Solution :
No. Plain text emails don’t include HTML.
HTML hadn’t even been invented when the email format was designed.
Most HTML emails are actually multipart emails with plain text and HTML parts that the client can select between (either based on its capabilities or with a UI).
