Have a clear purpose for the blast. Email blasting customers or partners is not an arbitrary task. Each blast should have a concise purpose before you begin to draft it. Determine what you're trying to deliver and how you want the recipients to react to the email. The blast's purpose could be enticing customers to purchase something, updating employees on a new project or initiative, or a newsletter to recap the month's events. Once you determine the purpose of the blast, you can work on making the message more clear to your recipients.
Then, let's say you write 30 blog posts a month. That means you'd get 60 leads in a month -- 2 from each blog post. Now keep doing that for a year. The work you did to blog that first month will continue to drive leads throughout the year. That means you're actually getting 4,680 opt-in contacts a month by the end of a 12-month period because of the compounding effects of blogging -- not just 720 opt-in contacts (60 leads*12 months).
Julie Ewald recommends moving away from sending generic content to your whole email list via e-blast entirely. With a little elbow grease, you can utilize segmentation and start sending off tailored messages to each of your lists with content that’s relevant, valuable, and designed to resonate with the kind of recipients that make up each segment.
