Many laws specifically regulate the ways online ads are delivered. For example, online advertising delivered via email is more regulated than the same ad content delivered via banner ads. Among other restrictions, the U.S. CAN-SPAM Act of 2003 requires that any commercial email provide an opt-out mechanism. Similarly, mobile advertising is governed by the Telephone Consumer Protection Act of 1991 (TCPA), which (among other restrictions) requires user opt-in before sending advertising via text messaging.
The best email copywriting starts with the subject line, which has to make recipients want to open your email. Follow that with an appealing headline so they’ll keep reading. Constant Contact’s research suggests that email copy should be short, around 200 words. It’s also wise to avoid being promotional in all your emails. Instead, offer value to your subscribers. The most important part is the call to action which leads recipients from the email to your site or resource.
Particular groups of customers can be targeted or even individuals. Offering individual customers special deals on merchandise and/or services on the customer's birthday, for instance, is one example of email marketing personalization. (A restaurant might send an email to customers on their birthday offering 50% off an entree,) Email marketing helps a business develop and maintain a relationship with a customer over time that hopefully results in increased sales and increased customer loyalty.
