An email sent or received using a provider other than the primary entity involved in the communication is considered a message facilitated by an external organization. For example, if Company A uses Solution B to send marketing communications to its customer base, those emails are being sent through a third-party provider. This arrangement contrasts with a scenario where Company A hosts and manages its own email servers and infrastructure.
The use of external email service providers presents numerous advantages, including scalability, deliverability enhancements, and access to advanced analytics and reporting capabilities. Historically, organizations have turned to these services to offload the complexities and costs associated with maintaining robust email infrastructure. This shift allows companies to concentrate on their core business functions while ensuring reliable and effective electronic communication.
