AT&T email best practices

Make sure you follow these guidelines and any laws when you send email through AT&T.

DETAILED INFO

AT&T email guidelines

To make sure your email gets delivered:
  • Follow any relevant Requests for Comments (RFCs).
  • Check if your message complies with the Federal Can Spam Act of 2003.
  • Send email through your ISP’s mail servers. If you use dial-up or other dynamic IP addresses, your email might not work.
  • Avoid sending a lot of emails all at once.
  • 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 appropriate header information. You can check yours by viewing the raw version 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.
