Donors, clients, partners and staff all rely on email communications from your organization. Email Marketing is shorthand for sending lots of emails - in bulk, one by one, or via "drip" sequencing.
Leading email marketing applications all provide a common set of featuers - content authoring, templates, open and click through tracking, customization and more. CiviMail is the email marketing component of CiviCRM and offers all of these features.
Additionally, CiviMail is fully integrated with the CRM database making it "one click" easy to select specific groups for emailing.
No more uploading lists to other email marketing applications. All email data is seamlessly integrated with other applications.
