Reply E-mail Automator
Does not matter if you are selling a product that you ship to your customers or a downloadable product like software or an E-Book. Your site may take orders and deliver your product automatically but there will always be a certain amount of E-Mail that you will need to answer every day.
You can save any response you wish into its database. If you have a certain E-mail support question you get that always requires the same 3 paragraph response, just save that response into REA's database along with a keyword that you will know equal's that response and Reply E-mail Automator will remember it.
