Email threading and how to change your threading mode

Conversation threading is a feature used to automatically group messages with their replies. Every email contains a unique message-id, which is automatically included in the references of the email header. When we receive an email, we loop in the references and message-id to see if we can find any similar conversations. If we do, we'll thread the incoming message to the existing conversation we’ve just found. If no message is found, then we create a new conversation.

Threads can be displayed in a variety of different ways. Front has several threading options depending on how you connect your email account. Any change to your threading mode will only apply to future conversations.

When you connect a Gmail account to Front, the default threading will be set to Gmail threading. This is where we thread messages in accordance with Gmail's logic in addition to regular email threading. See below section for the impact on syncing using this threading mode.

Regular threading is where we thread messages only if they reference a previous email in a thread with the same message-id. See below section for the impact on syncing using this threading mode.

We will thread messages where the recipients explicitly respond to each other (Regular threading), or when the subject and the recipients are the same (Subject-Recipient threading). This threading mode means that if messages do not reference a previous email in a thread with the same message-id, they can still thread if the subject and recipients are the same. In instances where recipients/subject are different, but the message does reference a previous email with the same message-id, these messages would still thread together, as this still meets the criteria for Regular threading.

Messages will only thread by recipients/subjects if received within 2 days of each other. See below section for the impact on syncing using this threading mode.

A new conversation will be created whenever you receive a new message. Your outbound replies will still thread with the incoming message it's replying to. Subsequent inbound replies to your message will not be threaded and will create new conversations. See below section for the impact on syncing using this threading mode.

Why does my Gmail inbox setting to Message view not reflect in Front?

In your Gmail inbox, you are able to set the view to be either Conversation view or Message view; however, this is not a change to the actual Gmail threading. It just how Gmail displays the view. Thus, changing the view in Gmail will not result in unthreaded conversations in Front - you would still need to change the threading setting in Front.

When you connect an Office 365 account to Front, the default threading will be set to Office 365 threading. This is where we thread messages in accordance with Office 365's logic. See below section for the impact on syncing using this threading mode.

Messages with the same subject line will be threaded together, only if the email recipients are the same. Messages will only thread by recipients/subjects if received within 2 days of each other.  If you send email campaigns or auto-generate emails to your customers that solicit responses, you'll want to select this option. Keep in mind, this only addresses outbound messages (recipients).  For inbound messages, we will thread based on the sender's email and the subject line. In instances where recipients/subject are different, but the message does reference a previous email with the same message-id, these messages would still thread together. See below section for the impact on syncing using this threading mode.

We will thread messages if it meets either threading options above. See below section for the impact on syncing using this threading mode.

A new conversation will be created whenever you receive a new message. Your outbound replies will still thread with the incoming message it's replying to. Subsequent inbound replies to your message will not be threaded and will create new conversations.

See below section for the impact on syncing using this threading mode.

Here's a further breakdown of when to use which threading mode: 

Gmail or Office 365 default threading: You will maintain a two-way Gmail or Office 365 sync for inbound/outbound emails, but spam status will no longer sync.

Regular threading is where we thread messages only if they reference a previous email in a thread with the same message-id.

We will thread messages where the recipients explicitly respond to each other (Regular threading), or when the subject and the recipients are the same (Subject-Recipient threading). This threading mode means that if messages do not reference a previous email in a thread with the same message-id, they can still thread if the subject and recipients are the same. Messages will only thread by recipients/subjects if received within 2 days of each other.

Note that with this threading mode, in instances where recipients/subject are different, but the message does reference a previous email with the same message-id, these messages would still thread together, as this meets the criteria for Regular threading.

A new conversation will be created whenever you receive a new message. Note that your outbound replies will still thread with the incoming message it's replying to. Subsequent inbound replies to your message will not be threaded and will create new conversations.

Step 1

Click the gear icon on the top right of Front and select company, workspace, or personal settings in the left sidebar, depending on the space you’re working with. Select Channels from the left menu.

Step 2

Select the channel that contains the channel that you'd like to change the threading mode for, then click the Settings tab.

Step 3

Navigate to the Threading mode setting and choose between the options listed.

Step 4

Click Save to finish changing the threading mode. 

Please note that changing your threading mode will not retroactively update past conversations. It will only apply on new conversations going forward. For information on changing the threading in an existing conversation, you can use the manual split or merge functions. 

When viewing a conversation in Front, messages will always be ordered with the oldest message at the top, down to the newest. The same logic will also apply to comments and other activities featured in the activity trail such as tagging and rules.

This order cannot be changed, in order to ensure conversations show as a chronological timeline that is intuitive to read from top to bottom.

Conversations that reach their message limits will automatically split off into new conversation threads. See this article for more information.
