MailPoet is an email delivery service and a product of Automattic, designed to support small businesses using the WordPress platform. It delivers both transactional emails, which support business operations, and marketing emails used to communicate with customers and audiences. The service provides the infrastructure through which these messages are sent, including the sendingservice.net domain and a published range of delivery IP addresses.

MailPoet also provides information to help recipients and administrators address email-related concerns. Its site links to an Anti-Spam Policy, Privacy Policy, and Terms and Conditions. People who receive spam or abusive messages from its network can report them by emailing [email protected], with the full message and its complete headers included to assist review. For technical matters, the service directs users to [email protected]. Together, these services and support channels reflect MailPoet’s role in email delivery for WordPress-based small businesses and its process for handling abuse reports and technical inquiries.
