Phone calls can be intrusive, and you may not be able to reach the customer when you call. Direct mail marketing can get expensive, and most people don't want more of what they perceive as junk mail. Email marketing, on the other hand, is an inexpensive way to provide customers with information they can read at their leisure. It is also effective because customers have already shown interest in your products or services. Before you can start an email marketing campaign, you must build an email list.
Subscribe to an email auto responder service. These services create a database for the emails you collect and allow you to send mass emails to customers.
Request existing customers' email addresses. If you have a brick-and-mortar business, you can ask for addressing when customers pay for goods or services. If you have an online business, you can place an opt-in form on the pages of your website. Auto responder services provide the HTML code you need to do this.
Offer one of your products or services for free in exchange for the customer's name and email address. This works especially well for online businesses that offer free e-books, programs, music or videos on their website and social media sites.
Put your email address on receipts and other business correspondence. When a customer contacts you by email, write back and request permission to email them about products, services and news pertaining to your company. Email auto responders can provide this service automatically.
