to find pretty easily once you have successfully installed a mailing list program onto your web site.
Moving on, you will need to set up a ezine/newsletter sign up box somewhere. Otherwise, how will you get new subscribers?!?
Now, any email list building system should have an HTML subscription premade code hanging around inside of it for you to access and use. Then it's just simply a matter of finding it, and 'copy and pasting' the HTML code into your existing web site or product. You could even generate your own squeeze page if you want to get really fancy (and also grab the immediate attention of your site visitors!). Not to be outdone, the idea of making use of a pop up window can be quite an attention getter and maybe even recruit more subscribers when they see them.
Now, a squeeze page is simply a plain old HTML page that is designed to do one thing and one thing only‌ make your site visitors subscribe to your mailing list. Therefore, it would be fairly easy to 'copy and paste' your HTML subscription form info inside one of these. You can see a fine example of a sign up system in place here.
Pop ups are a little different. But not too much. You still need to copy and paste the HTML code, but in this instance you'll need to do that within an existing code of another sort, usually a JavaScript. This will take a little more skill, but can still be done without too much hassle.
