I created a HTML template that I want to get into an email so it can be sent out, but how does one do this? I have Outlook 2016 and research I had read before with Outlook 2013 and below you could 'insert text' instead of the linked file, but Outlook have removed this.
I would be willing to use another program in order to get it into an email for sending out as a newsletter, so it doesnt need to be outlook.
By the way I wasnt sure what part of StackExchange to post this in, so I hope I have posted it in the right one.
Many thanks.
Outlook 2016 still does have the classic attach file button with insert as text, you just need to do a little work to get it (http://www.msoutlook.info/question/classic-attach-file-button)
My recommendation for inserting HTML into a desktop client would be Thunderbird (https://www.mozilla.org/en-US/thunderbird/). Outlook rewrites the email HTML before sending it out, which usually removes all media queries and can sometimes otherwise warp your display. Thunderbird uses a much friendlier engine and will allow your HTML to stay the same as it would on any popular Email Service Provider (such as SalesForce Marketing Cloud). Thunderbird has the option to literally "Insert HTML". This allows you to directly paste your HTML code and it populates in the editor.
For mail merge, you will need this add-on (https://addons.mozilla.org/en-US/thunderbird/addon/mail-merge/), which I actually find better than what you get in Outlook.
Finally, I just wanted to make sure that you are meeting CAN-SPAM compliance on your email newsletter as it is considered a commercial email and want you to avoid potential fines (up to $10,000 per email). (https://en.wikipedia.org/wiki/CAN-SPAM_Act_of_2003)
