## Meaning

To loop someone in means to add them to a conversation, email thread or meeting so they know what is happening. "Loop me in" means "include me from now on".

In tech workplaces, 'loop in' is a phrasal verb used to invite someone into an ongoing conversation or decision-making process. When you loop in a colleague, you are ensuring they have the information they need and can provide feedback or take action. This is commonly used in emails, meetings, and instant messaging platforms like Slack. For example, if you discover a bug that affects another team, you might say 'I will loop in the DevOps team so they are aware.' The phrase implies both inclusion and communication—the person is not just added to a list but is actively brought into the discussion. It is widely used across all levels of tech organizations because it emphasizes collaboration and transparency in decision-making processes.

## When you hear it

When you need to add someone to an email, Slack channel, or meeting to keep them informed.

## Examples

- **in an email:** "I will loop in Sarah from QA so she can review the test cases before we deploy."
- **in a standup meeting:** "We discovered a performance issue, so I looped in the infrastructure team yesterday."
- **in a Slack message:** "Let me loop in the design team to get their feedback on this mockup."

## What native speakers say

- "Let me loop in the product manager on this decision."
- "We should loop in the security team before shipping."
- "I will loop in our stakeholders on the timeline."

## Common mistakes

- ✗ "We looped in the problem to the senior developer." → ✓ "We looped in the senior developer to address the problem." (The person is looped in, not the problem. The person receives information about the problem.)
- ✗ "Can you loop me in this project?" → ✓ "Can you loop me in on this project? or Can you loop me into this project?" ('Loop in on' or 'loop in to' are more grammatically natural than just 'loop in' without a preposition.)
- ✗ "I looped in about the deadline." → ✓ "I looped in the team about the deadline. or I was looped in about the deadline." (You must specify who is being looped in, or use passive voice to indicate you are the person being included.)

## Be careful

Do not use 'loop in' for technical programming loops. It only means to include someone in communication. Also avoid 'loop in them' without specifying what they are being included in.
