Best email client that can generate template emails

I am converting over from the PC world to Mac and I need help finding an email client that performs like Outlook 2013. I usually send a ton of emails that have the same script to my clients and use "quick steps" in outlook for emails that are template oriented. This saves a ton of time. I would like to find something similar with my Mac. Does anyone have any suggestions or mail clients they think may work for what I need? I am sure there are plenty of work arounds, I am looking for a one click option, then add persons name and it sends the email out with the saved template info.

Thanks and I am so freaking glad I have changed over, now I need to work out the kinks.
