Maintain a Clean Email List: Regularly update and clean your email list to remove inactive or invalid email addresses. This reduces the chances of your emails being marked as spam. Obtain Proper Consent: Ensure that you have explicit permission from recipients before sending them emails. Use a double opt-in process to confirm their consent. Follow Best Practices: Adhere to email marketing best practices, such as providing a clear and easy way to unsubscribe, including your contact information, and avoiding misleading subject lines. Monitor Feedback Loops: Keep an eye on feedback loops provided by ISPs to identify and address complaints promptly.
