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,
