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.[1]
What I most like about Rejoiner is the shared accountability over results. Many brands spend large sums of money on email marketing software, only for the accountability of results to be on their internal team. With Rejoiner, this is flipped on its head, where the company providing the software shares the responsibility for driving incremental revenue. 
However, as email marketing developed as an effective means of direct communication, in the 1990s, users increasingly began referring to it as "spam", and began blocking out content from emails with filters and blocking programs. In order to effectively communicate a message through email, marketers had to develop a way of pushing content through to the end user, without being cut out by automatic filters and spam removing software.

Set your target audience. Audiences can be split up in a variety of ways including gender, age, geographic location, or buying habits. Before you send your blast, you want to make sure that you can segment people into different lists so you can target your blasts to the right people. Consider what demographic you want to target, and what they will need to fulfill your call-to-action.

I’m currently looking for an email marketing service for a mailing list of about 80,000 subscribers. I run an information product business in the fitness industry with a large number of customers buying our ebooks and online courses every day. I’m particularly interested in GetResponse, although I’d be keen to hear your thoughts on the flexibility of their service for creating autoresponders, and integrating with a checkout service (we use WooCommerce).
Email marketing is the practice of sending various types of content to a list of subscribers via email. This content can serve to generate website traffic, leads, or even product signups for a business. It's important that an email campaign's recipients have personally opted in to receive this content, and that each newsletter offers something of value to them.
