Email thread is one of the email management practices that assist you in getting the conversation flow in place. When you have an organization or business that uses email communication, email cluttering is a common scenario. This leads to using email threads to make your inbox more organized.

What is an email thread?

An email thread is a sequence or email chain that contains replies in chronological order. All the emails in this group indicate a specific topic that starts with the conversation. Here, emails don’t show individually but show with a group or thread that contains a series of conversations.

Email thread best practices 

Email communication gets easier when you don’t have an abundance of emails to reply to. When replying to a specific email consistently, it becomes a long message thread.

Email thread best practices


If there are two or more people involved, this will be considered a back-and-forth email, and keeping track of the responders will be difficult. 

Best practices for email thread


So, here are some of the best practices in the email thread you need to know. Check out!

Precise subject line

The first and foremost, to maintain proper email etiquette. The subject line should be precise, and to the point the email is all about. This will ensure the recipient comprehends what the email intends to say.

Otherwise, confusion arises about the email and leads to questioning or keeping it unopened by the recipient. 

Pro-Tip

If you find it hard to explain the email subject line, you can use the preheader text to explain what the email is about. 

Don’t send too many emails

There is a chance that you need to send several emails at a time. It stretches the conversation over time, and your inbox looks messy with no email threading option enabled. Sending too many emails may annoy the recipient and, ultimately, keep an incomplete conversation on what the email is about. 

Pro-Tip 

Always keep the conversation brief and don’t get diverted from the email topic.

Add Cc & Bcc when needed

When there are several recipients involved, and you need to add them to inform or hide their identity, use the Cc or Bcc options. However, try to avoid Cc or Bcc as it may create confusion among the recipients. When a conversation keeps going on, and Cc or Bcc joins in, it creates confusion in the email thread. 

Pro-Tip

Add Cc when it needs to, and they need to be in the email conversation and avoid adding Bcc to an email thread. Remember, you are one of the active senders here. The duty of an active sender of specific discussion keeps the group on track.

Avoid short responses 

Another reason your email conversation thread gets too long is using short responses. Responses like Good, Thank you, and All right are suitable for chat apps or business communication apps like Slack. Sending short responses in an email conversation makes the thread unnecessarily long and takes up the recipient’s inbox space. So, avoid short responses all the time.

Pro-Tip

If you need to respond in a short manner, stick to the email topic, mention something relevant to the previous conversation, and use email sign-offs at the end.

Notice the reply and reply all 

When replying to an email, make sure you respond to the person by Reply only. If there are multiple participants with Cc or Bcc and you need to reply to a specific person, use Reply only. Use the Reply all when you need to respond to all the participants in the email. 

Pro-Tip

Reply all will send a message to every participant with Cc or Bcc. If your email address is Bcc’ed and you Reply all, your email will be exposed to all the recipients. 

Decide whether to respond or not

If you are CC’ed in the email thread but not directly involved in the main conversation, avoid adding unnecessary responses. Doing so can extend the email thread and lead to off-topic discussions.

Pro-Tip

Respond only if you need to and send emails to the active participant or whom you are communicating with. 

Use conventional form for responding

Use the conventional form of communication for responding. This will ensure the email message maintains a professional and formal tone. You should maintain official and business communication using the conventional form of talking. 

Pro-Tip

Do not use any unconventional form of language, such as an informal way of expressing yourself or using irrelevant emoticons in the email body. 

Stick to a specific topic

If you have been asked questions that are out of topic, it might prolong the email conversation. Moreover, it might drag on another topic that is unrelated to your current conversation. So, stick to the single topic as much as you can. If you need to discuss something out of topic, open a new email string. 

Pro-tip

Notice the responder on what they reply, and evade the out-of-topic conversation or open a new message thread. This way, your email thread doesn’t get long or messy.

Craft emails with your conscience

Write emails to the point and clearly introduce your intent in the email body, subject line, and preheader. This will maintain email etiquette and relieve you of extended email conversations in the thread. 

Pro-Tip

Write an email in short form, summarize the complex points, and proofread it at the end to see if there’s anything you need to fix. 

Communicate over the phone for a detailed discussion

You won’t keep the conversation on with your recipient with endless emails. If you think you need to come up with a detailed discussion, plan for a meeting over the phone or video call. This will eventually relieve you from the long email threading.
