VinSuit is an excellent wine software that allows me to send out personalized emails with my customers favorite wines, as well as their current selections or what they want for upcoming events.
If I have questions about any one of these products there are also many support staff members who can help answer them quickly! Nothing in particular at this time but if you do not already use it please try it. Sending information updates on customer's orders/wines purchased during events has been greatly improved since using Vinsuite.
