Use an opt in page so people can join your list. This important as you want people who have given you permission to send them emails. They’ve done that because they’re interested in getting more from you.
Also, since they have done this you can then repeatedly send emails with useful information and with offers. In other words, the email communication can lead to sales. This is not the same as bombarding them with the latest offers all the time. This way you burn a list so that they get fed up with it, stop looking at your emails, and eventually unsubscribe. Nevertheless, having a list built by yourself provides you with your own market who are easily communicated with, and who want to hear from you.
One way to build your list is to ensure you always offer website visitors the chance to join it and so keep in communication with you. To do that you can put an opt in form on every page. At the time of writing, however, Google has recently expressed a dislike of squeeze-type page pop ups. But they think an exit pop-up, which can be the most effective in list building, is OK and will not penalize them. For WordPress sites you can get plugins that show an opt in pop-up when the visitors goes to leave the page.
Getting people to see the advantage of being on your list is important because it can take someone several times of seeing an offer before they decide to buy it. Thus the importance of repeatedly sending emails with your offer. Think of this as making the best you can of your profits.
