Best way to send responsive HTML email from a regular email client?
I've been researching a lot of options lately and it seems there are MANY resources to create responsive html emails to be distributed to many people at once, in a newsletter fashion.
I'm wondering if anyone knows of options to respond to emails individually from a regular client like gmail or hotmail, etc.
Basically, from my business account, I would like to send better looking emails with buttons, images, and a nice signature. So far I haven't been able to find any options that address this on a one by one basis.
