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.
  

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

Solutions

• Avoid using fake multi-thread emails to improve deliverability. 
  
• If you want your email recipients to recollect your previously sent campaigns, then you can include a reference to your previous newsletter in a box or within quotes as shown below:
  

  Scenario 1:
  

  When you send a campaign and want to ensure that your email recipients will remember your previous conversation/ campaign.
  



Scenario 2:


When sending an email to someone you met at a trade show or conference and want to make sure they remember your previous conversation.
