I will send out a small emailing using Thunderbird, then scale up to a service for a larger one.
What steps to I need to crete the email?
I need to create the HTML using Sublime and Chrome, and be sure all anchor tags resolve. So I will host the attachments on my server and reference them rom the email.
Have you got templates for outbound emailing I can use to find the one I like? This way at least colors, fonts and point sizes will be decided, freeing me to think of my copy and the attachments I'd use.
