6. Is email marketing still effective?Email marketing is one of the most effective ways for a business to reach its customers directly. Think about it. You don't post something on your site hoping people will visit it. You don't even post something on a social media page and hope fans see it. You're sending something straight to each person's inbox, where they'll definitely see it! Even if they don't open it, they'll still see your subject line and business name every time you send an email, so you're still communicating directly with your audience.
