Best practices for Email marketing regarding anti-spam laws

• Get consent: You’ve obtained express permission or opt-in from your list to send commercial email messages, and have explained the nature of the relationship you’re establishing. Make sure you have a record of this in case you ever need to provide proof.
• Clearly identify yourself: Your messages must clearly identify yourself or your company as the sender, and offer some way to reach you—like a physical address or a website, usually in the footer of your emails.
• Offer a way to opt out: Every email needs to provide a way to unsubscribe that lets the recipient remove themselves from all future communication.
