Make it easy to subscribe. Post a signup form on your homepage, blog, Facebook page, and wherever else your customers and fans are already active. You might want to collect names and birthdays (for a special offer or gift) or invite readers to join groups, but don't go crazy with the required fields. A too-long subscribe form might scare people off.
An email marketing strategy is part of your overall marketing strategy and business plan. It helps you market your products and services with the use of the email channel with the best chances for making a profit and reaching your goals. That is because an effective email marketing strategy takes into consideration what your target customers are, their preferences and benefits they are looking for as well as your products services and industry and which email marketing messages are most effective.
Win-back: An existing customer is soon approaching the end of his yearly subscription. The customer hasn’t used your product in 3 months and you need a way to win them back and keep them for another year. Create a “win back” email that sends an automated email to all customers that are coming to end of their contract with a list of new product features and a short plan on expected releases in the next six months.
When you're using email as a marketing tool, you're working on a pretty personal basis. This isn't ‘drive-by' stuff -you're directly targeting customers from their inboxes. There's a huge amount of potential which comes with this kind of marketing... but you'll only reap that potential if you REALLY understand both the marketplace you're operating from, and the audience you're talking to.
