Say you’re launching a beta test soon or collaborating with someone on a side project outside your typical newsletter scope. In an installment of the newsletter you usually send, briefly mention the project and provide a link where interested parties can go to sign up for updates about it. This way, those who aren’t interested only had to hear about it once and in a non-invasive way. A user experience win and a win for you, the guy who has two thumbs and a super-engaged email list sub-segment. 

Pop-up forms provide visitors with a quick, convenient way to share contact information and subscribe to your list while they’re browsing your site, making them a powerful tool for audience growth. They’re easy to add to your site, and they’re proven to work—our research shows that Mailchimp users have seen their list growth rate increase by an average of 50.8% after adding a pop-up form to their site. https://reallygoodemails.com/wp-content/uploads/2015/01/Have-You-Seen-Our-Top-100-Email-Marketing-Campaigns.png
One hundred years ago, companies such as Sears, Roebuck & Co. and J.C. Penny Co. used customer data to send out catalogs and mailers. Back then, the companies possessed small sets of data, mainly names and addresses of customers. Now, marketers have mountains of complex data and are faced with a modern conundrum: How much personal data is too much to incorporate into the content?
Push marketing is a proactive technique that enables e-marketers to "push" their product/service information to Web visitors or shoppers without their requesting it. Banner advertising, pop-up advertising, e-mail promotion, and spamming belong to push marketing. For instance, e-marketers can rent designated space from Internet service providers such as America Online or MSN for their banner or pop-up ads. Using animated graphics, appealing messages, and links, e-marketers try to lure visitors to their sites to buy their products or services. Many Internet users, however, find such ads annoying and employ software that blocks pop-ups and banner ads. <
