Stop Future Emails From A Thread

This option allows subscribers to block future emails from a particular thread.

By thread, we mean Replies to a previous email message.

Typically with the same subject line, but see below for technical discussion.

If you click on Yes

And you will not receive any more messages from that thread

There are no reporting options to see who is blocking what thread.

If you change your mind, you can see the messages in either the Searchable Web Archive or the Missing Message Archive

Ask your list moderator for the password.

The Missing Message Archive only keeps messages for 2 weeks.

What if the Subject Line is used again ?

Not a problem.

We are not paying attention to the Subject line, but rather a hidden header field in everybody's email.


This header is created by each subscriber's email reader, when they reply to a message.  It contains the Message-Id of the message they are replying to.

The Message-Id field is a long unique identifier.

So if multiple people reply to a message, the In-Reply-To field is the same on each reply.

What if the Subject Line is changed when replying

The In-Reply-To header will take precedence over the Subject Line, and thus an email thread could have different Subject Lines.

References: header

The References header contains a list of Message-Ids, when their are Replies to Replies.

The Stop Thread information is deleted after 30 days

So if somebody replies to a message thread more than 30 days later, that message will not be stopped.

You remain on the mailing list

Just emails from this one thread are blocked from coming to you for 30 days.
