MailerMailer is a service that helps users run their email-based marketing campaigns and newsletters. It can be used to create or import lists of recipients and will automatically remove bounces, unsubscribes, and invalid email addresses. MailerMailer also provides an editor for creating professional and visually-appealing email messages from scratch or with a template. Legally required features, such as an unsubscribe link, are automatically included.
MailerMailer also provides users with metrics on the number of opens, clicks, bounces, signups, unsubscribes, and complaints that their emails receive. It uses several authentication technologies to reassure ISPs that users' email messages are legitimate and improve the rate of successful delivery. Developers can connect MailerMailer to their websites or applications via XML-RPC API.
