Original Message Headers for a sent email

Help your contact find the original Message Header for your email in their email client to troubleshoot why they received multiple copies, why your emails are landing in their spam folder, or why they're having authentication issues

Occasionally our Customer Support team may ask you to provide us with a copy of the “Original Message Headers” for an email campaign sent from your Constant Contact account.

When are Message Headers necessary for troubleshooting?

Message headers let us see any patterns or error messages that may shed some light on the root cause of the problem. There are a few situations where we may ask for Message Headers:

• Multiple copies of emails received
• Email Delivery troubleshooting
• Email Authentication errors

More often than not, the contact's server, firewall, or email relay service is the reason contacts may be receiving duplicate emails, having your emails land in their spam folder, or having authentication errors. Unfortunately when this is the case, there is nothing that you as the sender can do, but we can further investigate for you.

How do I help my contact find the message header in their email client?

Before contacting Support, you'll need to obtain the message header for each of the problematic emails. First find out what kind of email client your contact is using, and then ask your contact to find the header information by following the following instructions for their email client:

• Microsoft Outlook instructions
• Yahoo Mail instructions
• Gmail instructions
• Apple Mail instructions
• AOL Webmail instructions
• Thunderbird instructions
