This is a particularly effective technique as not only is the potential to save money a great incentive to subscribe to their email list, but the actual discount itself is also a great motivator to make a purchase. So by offering first-order discounts to potential customers, La Mer is both building their email list and increasing sales at the same time. https://assets.pcmag.com/media/images/465640-email-marketing.jpg?thumb
A disadvantage of digital advertising is the large amount of competing goods and services that are also using the same digital marketing strategies. For example, when someone searches for a specific product from a specific company online, if a similar company uses targeted advertising online then they can appear on the customer's home page, allowing the customer to look at alternative options for a cheaper price or better quality of the same product or a quicker way of finding what they want online.
Once your list is targeted, you need to spend an equally large portion of time coming up with a great deal – even if it means you might lose a bit of money on it. The underlying goal of any marketing campaign is to gain new customers, and it’s worth it to significantly reduce your profit margins to gain said customers. Once you have a surgically-honed list and an amazing offer, then you can spend some time on the design, copy, delivery methods, postage rates, date of delivery, size of the mailer…there are a lot of other options to consider, but following the 40/40/20 rule you can see how important audience and offer truly are.
