AT&T email best practices

We have a few guidelines to help you make sure that your email gets delivered.

• Follow any relevant Requests for Comments (RFCs).
• CVerify that your email complies with the Federal Can Spam Act of 2003.
• Send email using your ISP’s mail servers. If you use dial-up or other dynamic IP addresses, your email might not work.
• Avoid sending multiple emails at one time.
• Remove your IP address from any Real-time Blackhole Lists (RBLs). If you’re on one, contact the list’s manager.
• Don’t send email from an IP address where the sender changes often.
• Use accurate header info. Check the header details by viewing the raw source code of a sent message.
• Don’t try to find email accounts by sending mass messages to spam our server. We’ll block these emails and may take legal action.
