Multi-thread Emails (Re./ Fwd. in email subject)

Multi-thread Emails (Re./ Fwd. in email subject)

To maintain a consistent conversation across many emails, multiple threads are used.  

Example: "Re: Fitness equipment order" or "Fwd: Fitness equipment order". Sometimes even two or more threads are employed. For instance,  "Fwd: Re: Fwd: Fitness equipment order"

Even before an email is delivered, the recipient's system checks chain conversations and identifies forged fwd:/re: emails. Any emails without the proper fwd/re footprints are quarantined, usually in the spam folder. If you add fwd/re tags in your email campaigns and your recipient finds out that there are no previous conversations, they may feel skeptical and mark it spam.

Email threads are maintained through the following technical information:

  • Message ID - a code created to maintain the identity of the first email and it's sender. 
  • Reply to/References - two values that are maintained over the course of a thread.
This technical information is automatically generated when sending an email.
A system can easily recognize a chained email thread by observing the presence or absence of the In Reply To and References. 
 
You may include "Re:" or "Fwd:" in the subject line or copy-paste breakpoints, style lines, and salutations in the content but the technical information  cannot be forged. 
Emails without proper In Reply To and References info with a subject line containing "re:" or "fwd:" will be quarantined or marked as spam. If the system recognizes enough fake multi-thread emails from the same source, the source domain's reputation will be degraded. In some cases, the domain may be blacklisted, unable to reach any customers via email. 

First Message will have a Message ID
First message will  not have In-Reply-To and Reference values

Message ID in email header

In-Reply-To and References will be found only in genuine reply or forward messages
