Whether you already have a list of subscribers or are starting from scratch, email marketing services can help. All of the services we cover let you add contacts manually using copy and paste or by uploading CSV or Microsoft Excel files. Some integrate with third-party software enabling you to import Gmail and other webmail contacts, Salesforce and other CRM data, or other software where you might have contacts stored. Depending on the size and location of your list, third-party integration could be key. Verify whether you can export contacts as well (and how easy it is to do so) should you leave the service. Managing users who unsubscribe should also be easy so you're not accidentally contacting anyone who has opted out of your newsletters.
Bloggers are the most obvious example of focusing on this email marketing strategy almost exclusively. SaaS (Software as a Service) businesses are another group that typically heavily emphasize content emails. Of course, bloggers, SaaS businesses, and everyone else can send content emails while also using the other email marketing strategies. And you should do it, too.
