If you have a website, an email newsletter is a message that you send out to your subscribers daily, weekly, bi-weekly, monthly, or annually. Your newsletter can contain your blog posts or news about your upcoming book, appearances, promotional events.
Tip #1 : When readers subscribe to your newsletter, send them a welcome email, with sample chapters from your book.
Tip #2: Before start sending emails, use tools to validate bulk email addresses in order to decrease the bounce rate of your email campaigns.
Tip #3: The subject line of your email will determine whether or not your email is opened so make it count.
