Mimi's Booster Message does not support embeds directly
Mimi's Booster Message is a feature in the Mimi messaging app that lets you pin a message to the top of a conversation so everyone sees it first. The feature itself does not have a built-in embed function — you cannot attach a link preview, video player, or interactive element that displays inside the pinned message itself.
What you can do instead is pin a regular message that contains a link, and Mimi will show a preview of that link below the text. The preview appears as a card with a thumbnail, title, and description pulled from the webpage or video you linked to. This is not the same as an embed, but it serves a similar purpose: it shows your contacts what the link points to without them having to click it first.
If you need something more interactive — like a live-updating counter, a form, or a media player that works inside the message itself — Mimi does not offer that through Booster Message. You would need to use a different messaging platform or share the link in a regular message and ask people to open it in their browser.
Key Takeaways
- Mimi's Booster Message feature pins text to the top of a chat but does not support true embeds or interactive elements.
- You can pin a message containing a link, and Mimi will display a preview card showing the link's title, description, and thumbnail.
- Link previews appear automatically when you paste a URL into a message — no special formatting or settings required.
- If you need interactive embeds like forms or live widgets, you will need to use a different messaging app or share the link separately.
How to pin a message with a link in Mimi
Open the Mimi app and go to the conversation where you want to pin a message. Type your message and paste the link you want to share. Mimi will automatically generate a preview card below the link showing the webpage's title, a short description, and a thumbnail image if one exists.
Once the preview appears and looks correct, press and hold the message (on mobile) or right-click it (on desktop). A menu will appear with options including "Pin Message" or "Pin to Top". Tap or click that option. The message will move to the top of the conversation and stay there until you unpin it or someone with admin permissions removes it.
Everyone in the conversation will see the pinned message at the top of the chat, including the link preview. They can click the preview card to open the link in their browser, or they can click the link text itself. The pinned message stays visible even as new messages arrive below it.
What kinds of links show previews in Mimi
Most standard websites and video platforms generate previews automatically. If you share a link to a news article, blog post, YouTube video, or product page, Mimi will pull the title and description from that page's metadata and display it as a card. Social media links (Instagram, Twitter, TikTok) also generate previews showing the post content or a thumbnail.
Some links do not generate previews — this usually happens when a website blocks preview requests or does not include the metadata Mimi needs to build a card. If a link does not show a preview, the message will still pin, but it will appear as plain text with just the URL showing. The preview will not appear later if the website adds the metadata; you would need to delete and re-pin the message.
Shortened URLs (like bit.ly or tinyurl links) sometimes fail to generate previews because the shortener does not pass through the original page's metadata. If a shortened link does not preview, try pasting the full original URL instead.
Pinning multiple messages or updating a pinned message
Mimi allows you to pin more than one message in a single conversation. If you pin a second message, both will appear at the top, usually with the most recent pin shown first. You can pin up to a limit that depends on your Mimi plan — free accounts may have fewer pinned messages allowed than paid accounts.
If you need to change what a pinned message says, you cannot edit it directly while it is pinned. You must unpin it first, edit the message text, and then pin it again. The link preview will update if you change the URL, but if you only change the text around the link, the preview card will stay the same.
To unpin a message, press and hold it (mobile) or right-click it (desktop) and select "Unpin" from the menu. The message will drop back into the normal conversation flow but will not be deleted.
Why you might want a pinned message instead of an embed
Pinned messages work well for announcements, rules, or important links that everyone in a group chat needs to see. Because the message stays at the top, new members joining the conversation will see it when ready without scrolling through old messages. This is useful for sharing a group's guidelines, a shared document link, or a schedule that does not change often.
The link preview card makes it clear what the link points to without requiring people to click it. This reduces confusion and means people can decide whether they want to open the link based on the preview alone. For a group chat, this is often more practical than trying to embed interactive content, which most messaging apps do not support anyway.
Alternatives if you need more than a pinned link
If you need to share something that requires interaction — like a form, a poll, or a live-updating widget — Mimi's Booster Message will not work. Instead, you can share the link in a regular message and ask people to open it in their browser. Many services like Google Forms, Typeform, and Slido are designed to work this way and do not need to be embedded inside a messaging app.
Some messaging apps like Slack or Microsoft Teams offer more advanced embed options through integrations or bots, but Mimi does not have this feature. If your group regularly needs interactive elements in your chat, you might consider whether a different platform would work better for your use case.
For most groups, a pinned message with a link preview is enough. It keeps important information visible, shows people what they are clicking on, and does not require them to learn new features or settings.
Frequently Asked Questions
Can I embed a video directly into a Booster Message?
No, Mimi does not support direct video embeds in pinned messages. You can pin a message containing a YouTube, Vimeo, or other video link, and Mimi will show a preview card with a thumbnail. People can click the thumbnail to open the video in their browser, but the video will not play inside the message itself.
What happens to a pinned message if I edit it?
If you edit the text of a pinned message, the change appears when ready in the pinned message at the top of the chat. If you change the URL in the message, the preview card will update to match the new link. You do not need to unpin and re-pin the message for edits to show.
Can other people unpin my message?
This depends on the conversation settings and who has admin permissions. In most group chats, only the person who pinned the message or a group admin can unpin it. In one-on-one conversations, either person can unpin messages. Check your conversation settings to see who has permission to manage pinned messages.
Will the preview card update if the website changes?
No, the preview card is a snapshot taken when you first pinned the message. If the website updates its title, description, or thumbnail image later, the pinned preview will not change automatically. You would need to unpin the message, delete it, and pin a new message with the same link to see the updated preview.
Can I pin a message that contains multiple links?
Yes, you can pin a message with multiple links. Mimi will usually show a preview card for the first link in the message. The other links will appear as plain text. If you need previews for all the links, consider pinning separate messages for each one.
