Let me say right out of the gate, that I would still recommend Aweber to business owners. It’s a great solution and is well regarded in the industry, particularly for their rigour of asking for the double opt-in to minimize spammers and assure permission (this is where a subscriber has to confirm via email that they do in fact want to receive information). It’s reasonably priced, and has many of the basic features needed to do good email marketing. MailChimp is comparable too – however, despite my love for their awesome branding, it lacks features that even Aweber has down. It’s great for a basic business owner.
Now, you can automatically send highly relevant emails encouraging them to buy the product or service they were considering. Customers who received multiple abandoned shopping cart emails are 2.4 times more likely to complete the purchase than those who receive only one followup email, according to Experian. Try sending the first message one day after, a second message 48 hours after, and possibly a third message within three or four days of abandonment.
