Including ads in email footers to other brands is generally acceptable under certain conditions. Key factors include relevance to the recipient's interests, avoiding misleading or spammy content, ensuring clear identification of the ads, and providing an opt-out mechanism. Compliance with anti-spam laws like CAN-SPAM and privacy regulations like GDPR is crucial, particularly regarding explicit consent for EU residents. It's also recommended to monitor deliverability and user engagement, potentially using A/B testing, and to avoid negatively impacting the user experience. Checking the Acceptable Use Policy (AUP) for relevant restrictions is advised.
