Comments let a team discuss a template inside the [Topol Email Editor](https://docs.lettr.com/learn/templates/topol-editor.md). Each comment is attached to a **block or a section** of the template, so a note about a headline sits next to that headline for everyone who opens the template. Comments work in transactional templates and in campaign content, on all plans. ![The Lettr email editor with the comments panel open on the left, showing a conversation of three comments with thumbs-up reactions and a Reply box, next to the template canvas where the headline block the conversation belongs to is outlined in green](https://mintcdn.com/lettr/v9sgBVA72FniI0eN/images/comments-thread-on-block.png?fit=max\&auto=format\&n=v9sgBVA72FniI0eN\&q=85\&s=c94ff7b12c148cfe7708aeee4dc203c1) ## How comments are organized Every comment belongs to a **conversation**, and a block or section has at most one. The first comment on a block starts its conversation, and every later comment on that block is a reply in it. Comments are stored separately from the template's design, so they never appear in a sent email or a test email. Saving or publishing a new [version](https://docs.lettr.com/learn/templates/versions.md) of the template leaves them in place. > [!NOTE] > > Comments are part of the visual editor. Templates written in custom HTML don't have them. ## Start a conversation **1. Pick the block or section** Hover over the block or section the comment is about. Its controls show a speech-bubble icon with the tooltip **Comment**. **2. Write the first comment** Click the icon. The comments panel opens on that block with a **Start conversation** box. Type the comment and send it with the arrow button. ## Reply, react, and resolve Open a conversation to see all of its comments, and add one with the **Reply** box at the bottom. New comments, replies, reactions, and resolved conversations appear for everyone who has the template open, with no reload needed. * **Reactions**: each comment has a thumbs-up and a thumbs-down button. Each person has one reaction per comment, which they can switch or take back. * **Editing and deleting**: hovering over your own comment shows a menu with **Edit comment** and **Delete comment**, as long as it's still the latest comment in the conversation. Nobody can edit or delete someone else's comment. Deleting the only comment in a conversation deletes the conversation too. * **Resolving**: the check button at the top of a conversation marks it resolved once the change is made. Resolved conversations drop out of the list but aren't deleted. Turn on **Show resolved** to see them again and reopen one. * **Deleting a conversation**: **Delete conversation** in the conversation's menu removes it with all of its comments. Any teammate can do this. ## Mention a teammate Type `@` in a comment to open the list of teammates, and pick the person who should look at it. The list holds everyone on your team except you. ![A reply being typed in the comments panel, with the @ mention list open below it showing two teammates, Maya Chen and Tom Becker](https://mintcdn.com/lettr/v9sgBVA72FniI0eN/images/comments-mention.png?fit=max\&auto=format\&n=v9sgBVA72FniI0eN\&q=85\&s=e634c62b6a1a856d53e02daab2b26ab7) Each teammate mentioned in a new comment gets an email with the subject **\[author] mentioned you in \[template]**. It quotes the comment and has an **Open template** button that opens the template in the editor. Only new comments send these emails, so a mention added by editing a comment doesn't notify anyone. ![The mention email: You were mentioned in a comment, Tom Becker mentioned you in a comment on the template Winter collection launch, the comment quoted below, and an Open template button](https://mintcdn.com/lettr/v9sgBVA72FniI0eN/images/comments-mention-email.png?fit=max\&auto=format\&n=v9sgBVA72FniI0eN\&q=85\&s=74ccb2f949a24fee052af5c5d2b356e4) ## Find open feedback The **Comments** icon in the editor's left sidebar opens the list of conversations in the template. Each entry shows the people involved, the block or section it belongs to (named by its ID, such as `#SkQ9mLp3e`), the latest comment, and how many replies it has. A dot marks conversations with comments you haven't read. ![The list of conversations in the comments panel: three entries, each with the avatars of the people involved, the block ID it belongs to, the latest comment and a Reply or 2 replies link](https://mintcdn.com/lettr/v9sgBVA72FniI0eN/images/comments-conversation-list.png?fit=max\&auto=format\&n=v9sgBVA72FniI0eN\&q=85\&s=b77692eed00f7bf6665e7e5b5df63ad1) The menu at the top of the list sorts conversations with **Sort by date** or **Sort by unread**, and **Show resolved** adds resolved conversations back in. Opening a conversation marks it read, and **Mark as unread** in the conversation's menu flags it again for later. ## Who can comment Every member of the team can read and write comments, whatever their [role](https://docs.lettr.com/learn/settings/teams.md#team-roles). Comments are part of every plan, and there is no limit on how many people take part. To bring a reviewer in, [invite them to your team](https://docs.lettr.com/learn/settings/teams.md#inviting-team-members). ## Related topics > **[Topol Email Editor](https://docs.lettr.com/learn/templates/topol-editor.md)** > > The editor's layout model, blocks, and toolbar > **[Template Versions](https://docs.lettr.com/learn/templates/versions.md)** > > Save, publish, and roll back template versions > **[Team Management](https://docs.lettr.com/learn/settings/teams.md)** > > Invite teammates and manage roles > **[Saved Blocks](https://docs.lettr.com/learn/templates/saved-blocks.md)** > > Reuse sections across templates This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
