A good mailing list is essential to the success of an email marketing campaign. It doesn’t matter whether you have 10s or 1,000s of page views daily but if you have no way of persuading these visitors to return to your website in future, then all your efforts to increase sales may go to waste. It has been proven that repeat visitors usually end up being customers.

Mailing lists had been used even before the Internet exists when businesses started posting newsletters and promotional materials via snail mails. When Internet and email were introduced, this marketing method too went digital and businesses started sharing their promotions and updates through emails.

Another very important thing to remember when building mailing lists is that it should be permission-based. Don’t spam. Getting your customers to opt-in and agreeing to receive mailing lists is the ethical way and will improve your reputation while ensuring fewer bounced emails and un-subscriptions later.

Many businesses offer customers incentives or special deals to subscribe to their newsletters. It doesn’t need to be something expensive. A free e-book or a discount on the first purchase is sometimes good enough.
