Keep engaged with your retained customers by sending some informational, greeting emails. Build a strong connection with them by providing some additional values. Acquire new customers by offering something valuable to them and keep acknowledging them with the coming offerings.

You must give your customers a reason to open your email, read your message, and then visit the website. I'm using BlueDot Email for doing email marketing.
