Do you know how many visitors to your winery Web site put wine into their online shopping cart and then abandon it (i.e. leave without completing the purchase)? Do you know how many of them come back and finish the order at a later time? Can they even do that?
Even if you don't know these important e-commerce statistics for your site, you should read this article on automatically e-mailing shoppers who abandon their carts. (If you're thinking about reading it later, print out a copy, as MarketingSherpa articles are only free for 10 days, and this one will disappear into their extensive library of case studies on October 22nd, where it will cost you nine bucks).
One of the thing I like about MarketingSherpa articles is that they usually have a sample of the e-mail or other creative work mentioned in the case study. I also like the fact that their newsletters are free and full of useful, real-life information.
I expect that Inertia Beverages will snap up this auto-email idea for their customer base (one of the reasons to consider a firm like Inertia, Cultivate, or eWinerySolutions is that you usually get the benefit of ideas that they work on for other clients).
Remember, someone who abandons a cart (as many as 59.8% of shoppers in some cases) was almost ready to buy. You need to (a) understand why that happens if you can, and (b) nudge them gently past their reluctance.
