# Create and submit a post > Start a draft for a channel, write the body, attach media, set a time, and send it to review. Source: https://docs.use-mark.com/docs/create-and-submit-a-post Write a post in the post editor, then submit it for review. For what each status means, see [Review and approval](/docs/concepts/review-and-approval). Open your posts from the sidebar: **Content** > **Posts**. Tabs split them by where each one is: * **Needs review**: submitted and waiting for a decision. See [Review and approve posts](/docs/review-and-approve-posts). * **Drafts**: drafts, and posts sent back with changes requested. * **Scheduled**: approved and scheduled posts, soonest first. * **Published**: posts that went out, newest first. * **All**: every post, newest change first. Each row shows the **Post** (its first line, or "Untitled post" if the body is empty), the **Channel**, the **Status**, and when it **Goes out**. On a phone, the channel shows as its logo and the time is hidden. Filter any tab by **Channel** and scheduled date. If there are no posts yet, **All** says "No posts yet. Start one with New post." ## Start a draft 1. Select **New post**. 2. Pick a **Channel**. 3. Select **Create draft**. The post opens in the editor. To switch channels later, change **Channel** in the editor. Fields that the new channel doesn't use are cleared. ## Write the post The editor shows the post's status at the top, next to **Channel**. * **Body**: write the post. The counter shows its length against the channel's limit, like 180 / 2200 on Instagram. Over the limit, the counter turns red and the editor says "The body is over the 2200 character limit for instagram." **Save draft** and **Submit for review** can't be selected until you shorten it. See [Social post text](#social-post-text) for how the body is sent and counted. * **Angle**: pick an angle for the post, or leave it on **No angle**. Angles come from **Strategy** > **Angles**. For setting them up, see **Create and assign angles**. * **Scheduled time**: pick the date and time the post should go out, in your timezone. Leave it empty if you don't know yet. * **Media**: select **Attach media**. In the dialog, drag files in to upload them, or select files this workspace already uploaded. Select **Done**. To take a file off the post, select the remove button (**×**) in the corner of its thumbnail. If uploading isn't available in your workspace, the dialog says so. Files that are already uploaded are still there to pick. * **Details**: fields for the channel you picked, so they change when the channel does. Fields marked with **\*** are required. A field that reads "One value per line", like Instagram's **Collaborator usernames**, takes each value on its own line. The preview beside the editor updates as you type. See [Preview the post](#preview-the-post). ## Social post text Instagram, X, Facebook, LinkedIn, TikTok, Pinterest, and YouTube bodies are plain text. Mark sends them exactly as you type them. These platforms don't format Markdown, so `**bold**` or `[text](link)` would show up as those characters. Use line breaks for structure and paste links as the full URL. Blog posts, FAQs, and competitor pages are different. Their body is a formatted editor, and the website renders the formatting. ### X counting and threads X counts characters its own way, and the counter follows it: * Every link counts as 23 characters, however long it is. * An emoji or a Chinese, Japanese, or Korean character counts as 2. To post a thread, write the first post in **Body**, then write each reply in **Replies** under **Details**. Each reply has its own box and keeps its line breaks. Select **Add to replies** for another box, or **Remove** beside one to drop it. Each reply is counted on its own against X's 280 limit. Empty replies are dropped when you save. ### TikTok videos TikTok publishes videos only to everyone. For a post with a video, set **Who can view** to **Everyone**. Any other choice stops the save with "TikTok only publishes videos to Everyone." The other choices work for photo posts. ## Preview the post The preview shows the post the way the channel you picked shows it, with its media laid out for that channel, and several Instagram images or videos as a carousel. It counts characters the same way as the counter. On X, it shows the first post, then each reply with its own count. * On X, a post with no media shows a link card for its last link. * On Facebook, a post with no media shows a link card for its first link. * Required **Details** fields that are still empty are listed under the preview, like "Who can view is required." A preview shows what Mark will send. It doesn't guarantee the platform accepts the post. ## Save or submit * Select **Save draft** to keep your work. **Saved** appears next to the buttons. The post stays a draft and stays editable. * Select **Submit for review** when it's ready. Mark saves the post first, then sends it to review. The status changes to in review. If the channel's **Approval policy** is **Auto**, Mark can approve it right away instead. See [Connect social accounts](/docs/connect-social-accounts). If something needs fixing, the editor says so above the buttons. "Some fields need attention." means a **Details** field has a problem. The message shows under that field. Once you submit, the post is locked. Trying to save it shows "This post is locked for review. It can be edited again after a reviewer requests changes." To see what happens next, read [Review and approve posts](/docs/review-and-approve-posts). ## Edit a post later Select a post in the **Posts** list to open it in the editor. Drafts and posts with changes requested stay editable. Other posts are locked. After a reviewer requests changes, fix the post and select **Submit for review** again.
