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.
