The Composer in WEMASY Social media is where you write a post once and send it to one or more connected accounts. You see a preview per platform while you type, and you choose to schedule it, publish it now or keep it as a draft.
Where to find it
Open Social media from the product switcher and click Composer in the left menu. You can also click New post on the Overview, Queue or Calendar page.
Write and schedule a post
- Under Post to, click the chip of each account you want to post to.
- Under Content, type your text in the field What do you want to share?
- Optional: enter a web address under Link.
- Optional: click Upload or choose from library to add images or a video.
- Check the cards under Preview.
- Under Schedule, pick the date and time.
- Click Schedule.
Times are in your local timezone. Click Publish now to post right away, or Save draft to finish the post later.
Different text per platform
When you post to more than one platform, click Customize per platform. A field appears for each platform. Leave a field empty to use the default text, or write a shorter or different version, for example for X with its 280 character limit.
Text per language
If one of the chosen accounts has another language set on the Accounts page, the composer shows a tab for that language next to the main text. Write the text in that language on its tab. An empty tab means those accounts get the main text.
Images and video
Upload or choose from library opens your media library, where you upload files or pick up to 20 existing ones. You can also click Add image URL and paste the address of an image. Give every image an Alt text for visitors who use a screen reader.
- Images can be up to 10 MB and videos up to 200 MB. A file that is too large shows a message and blocks saving.
- For a video you can add a Video cover, a JPG or PNG. Instagram uses it as the Reel cover and Facebook as the video thumbnail. YouTube uses it as the thumbnail for verified channels.
- For Facebook you choose under Facebook video as whether the video becomes a Reel, a Page video, or the automatic choice: a Reel when it is vertical and at most 90 seconds.
- For YouTube you add one video, a YouTube title and a YouTube visibility: Public, Unlisted or Private. Videos can be up to 256 MB. A vertical or square video of up to 3 minutes becomes a Short.

The fields Format, Hook, Content line, Cut, Script and Pack are optional. Fill them in when you want to compare groups of posts on the Performance page.
Frequently asked questions
Is a link in an Instagram caption clickable?
No. Instagram does not make links in a caption clickable. Put the link in your Instagram bio and mention it in the text.
Can I change a post after I scheduled it?
Yes. Open Queue and click Edit on the post while it is still a draft or scheduled. A post that is already published cannot be edited from WEMASY.
Tip: Write the main text for the platform with the most room, then use Customize per platform for X and Bluesky.
