Email Templates functionality like 'AbleBits Addin collection for Outlook'

I have been reviewing the Pro version to purchase, and one function that would be really helpful for marketing emails and replies is to have a flexible Template system, like the AbleBits Addin I am currently using with Outlook.

Do you have something like this in development for a possible future release?

+1 for this feature. I run Thunderbird as another email client just so I can use this feature in Thunderbird!
