There are no free email marketing lists. It is against United States law to harvest emails for business purposes using a marketing service. However, there are other ways to build up a solid contact list for your marketing plan.
The first thing you need to do before you even think about building a list is to review your home nation's digital laws regarding personal email addresses. Each country is different, so you definitely want to know what the stance is of the home government before you build up your email list.
After studying the legal aspects of email marketing, you can start building a functional list. One of the best ways to do this is through social media. Social media is an excellent method for getting close to your target audience without seeming intrusive. You can get an interested customer's email by asking them to subscribe to your blog. This way, the customer is giving you permission to send them your marketing documents such as coupons, catalogs and whatever else you have put together.
You can also cut time by hiring an email marketing specialist, either at an advertising agency or on the freelance market, to draft all your marketing copy and managing your email list; this way, you never need to be bothered by creating effective marketing.
