Newsletters are an important reinforcement of your brand.
They show off your expertise to both existing and potential customers, with valuable content that reminds them why they care about your business. Newsletters need to have engaging, fun and social content balanced with relevant business news and insights. You want to be human. You want to be an authority in your industry. You want to engage with your customers and create new business opportunities.
As an added bonus, place your newsletter on your website and you can increase subscriptions, thus building out your mailing list.
