Consent Obtaining consent is a cornerstone of most email marketing regulations. This can be either explicit, where the recipient has clearly agreed to receive emails, or implicit, where the recipient is an existing customer.
Identification Email marketers must clearly identify themselves in their communications. This includes providing a valid physical postal address and possibly additional contact information.
Unsubscribe Mechanism All commercial emails must include an easy and obvious way for recipients to unsubscribe from future emails. This process must be simple and free of charge.
Content Regulations The content of the email must not be misleading. Subject lines should accurately reflect the content of the email, and any offers or promotions should be clearly explained.
