I am writing a software to send transactional emails and I had several issues when it comes to sending emails with plain/text and text/html.

I know that it is not advised to send emails without plain/text portion but I am really considering it.

So, here is my question. Nowadays, is it a concern if I send emails with text/html but without plain/text portion?

I have tested it with Gmail, Hotmail, and Microsoft Outlook (via Microsoft Exchange) and it worked very well so far.

Thanks,

Rafa

    It will fail for anyone who sets their mail client to display text-only emails, or for any organisation that explicitly strips HTML emails from their mail traffic. People do this for very good security reasons –  Jun 13 '13 at 21:31
  • Older Blackberrys cannot display HTML at all, so if your audience includes those users they will see nothing. – samanthasquared Jun 14 '13 at 13:41

    If you're able to write such a software, you can write small code (or find it on many open source projects) to convert HTML text to plain text. – Alysko Jun 20 '13 at 09:13
  • Instead of resorting to this, maybe make a question with the issues you've encountered sending emails with text/plain and text/html. Who knows, you might find a solution (though I guess it's a bit late for that though). – gdvalderrama Sep 19 '17 at 09:41
  • Yes, I did. It was solved in this thread: https://stackoverflow.com/questions/17097806/send-email-via-smtp-with-attachment-plain-text-and-text-hml – Rafa Sep 19 '17 at 15:12

Well, old devices may not be able to display text-only format properly as mentioned by samanthasquered. But, in my case mail-filters (spam filters or any filter created manually as mentioned by Mike W) would be a bigger concern.

Here is the best reference I could find about this topic: http://blog.hubspot.com/blog/tabid/6307/bid/32643/Why-Marketers-Must-Optimize-Emails-for-HTML-AND-Plain-Text-Infographic.aspx
