An email newsletter is a message that is sent out to subscribers typically on a regular interval. Email newsletters may be sent daily, weekly, bi-weekly, monthly, or even annually. The content of email newsletters varies with each edition. Some email newsletters are so popular that they can sell advertising space. Email newsletters typically focus more on providing information and less on sales promotion, which helps businesses establish themselves as experts in their fields. Nonprofit organizations often use them to announce upcoming events to members and volunteers. MyNewsletterBuilder (MNB) provides an advanced WYSIWYG editor and hundreds of custom email newsletter templates to make your email newsletters more visually appealing for higher open rates and click-through rates.
