“Blasting” suggests that you’re sending the same email out to all your subscribers. That there’s no personalization, even in the subject line. No dynamic content, and no way for subscribers to let you know which topics they’re interested in. In the example of my real estate marketer friend, her blasts go out all as one version to buyers and sellers alike.
If ebooks aren't your jam, create tools instead. I don't recommend a one-or-the-other approach, necessarily, but if you have more development talent than writing talent, this may be a more attractive option for you. These tools can be valuable enough to some of your website visitors that they'll trade you their email address for a free demo of the product you built. Then, for your first email, ask them what they thought of the tool. It's the perfect icebreaker.
The benefit of that is when you do need to announce a new product or sale, you can count on the fact that you’ve already been in touch, having built a relationship over several weeks/months, and are much less likely to annoy your readers. Of course, it’s important to schedule your autoresponder sequence on specific days so that you know when you can afford to send an email. More than one per day and you’re probably mailing too much.
How do you find the sweet spot? The best way is to monitor statistics from your email blast software. See how many recipients open your emails, how many click a link, and how many unsubscribe. (Pay attention to the type of recipient, too, as your open rates for loyal customers will be different from new prospects.) Learn what works, make changes, and test again.
E-marketing refers to the use of the Internet and digital media capabilities to help sell your products or services. These digital technologies are a valuable addition to traditional marketing approaches regardless of the size and type of your business. E-marketing is also referred to as Internet marketing (i-marketing), online marketing or web-marketing.
Are you really willing to risk not only your email deliverability, but also the reputation of your IP address and your company? Even if you find the light after purchasing or renting email lists and decide to only email those who have opted in with your company, it'll take you months (or maybe years) to get your Sender Score up and rebuild the reputation of your IP.
