# Send Facebook Messenger messages
To send a one-time Facebook Messenger message in Pushwoosh, navigate to the **Campaigns** section, select **One-time messages**, and click **Send message > Facebook Messenger**.
## Compose your message
In the **Content** step, enter your message in the text field.
## Use a message tag outside the 24-hour window
Meta only delivers free-form content inside the 24-hour window opened by an inbound message from the user. Outside that window, select a **Message tag** matching one of Meta's approved use cases, or the send fails. See [message tags](/product/customer-journey/journey-elements/channels/facebook-messenger/#use-a-message-tag-outside-the-24-hour-window) for the full list and how Pushwoosh handles a closed window.
## Select the audience for your Facebook Messenger campaign
In the **Audience** step, define who will receive your message.
### Send to segment
Target a predefined [segment](/product/audience-data-and-segmentation/segmentation/) of your audience based on tags, events, or behavior. Select a segment from the dropdown, or click **Create segment** to [build](/product/audience-data-and-segmentation/segmentation/create-segments/) or [import](/product/audience-data-and-segmentation/segmentation/create-segments/by-import/#how-to-import-a-segment) one.
### Send to all subscribers
Target your entire Facebook Messenger-reachable audience.
Once you've set your audience, click **Next** to proceed to the scheduling step.
## Schedule your message
Choose when to send your Facebook Messenger message.
### Send immediately
Send the message as soon as the campaign setup is complete. This is ideal for urgent or time-sensitive messages.
### Selected time
Schedule your message for a specific date and time.
* **Set the date and time**: use the calendar to pick the date, then specify the time in hours and minutes (24-hour format).
* **Select the timezone**:
* **Subscriber's device timezone**: the message is sent at the specified local time for each recipient.
* **Custom timezone**: the message is sent at the same time for all recipients, useful for targeting a particular region.
### Set frequency capping
Use [**Frequency capping**](/product/messaging-channels/global-frequency-capping/#enable-global-frequency-capping) to limit how often users receive Facebook Messenger messages, preventing over-messaging. Choose one of the following options:
* **Use Global frequency capping settings**
Apply the project-wide limits configured in your [Global frequency capping settings](/product/messaging-channels/global-frequency-capping/#enable-global-frequency-capping). For example, if the global limit is 3 messages in 9 days, additional messages exceeding this limit are skipped.
* **Ignore Global frequency capping**
The user receives this message even if they've exceeded the channel's message limits. Use with caution to avoid over-messaging.
* **Use custom frequency capping**
Set a custom message limit for this message. If the user exceeds this custom cap, the message is skipped.
Choose a counting mode for this custom limit: [Rolling window or Calendar day](/product/messaging-channels/global-frequency-capping/#configure-global-frequency-capping).
## Review and send
In **Review**, check the preview and the summaries for content, audience, and schedule. Update anything that still needs to change before you send.
Once everything is verified, click **Schedule** to set it for later delivery or **Send Now** to send it immediately, depending on your selected scheduling options.
## Manage a scheduled message
For Facebook Messenger messages that are scheduled and not yet sent (status **PENDING**), you can change or cancel them. Open the list of messages in **Campaigns → One-time messages**, then open the actions menu (⋮) for the message:
* **Edit message**: opens the Facebook Messenger form with the message data loaded. You can update the content, message tag, audience, schedule, and delivery settings.
* **Delete message**: cancels the scheduled delivery and changes the status to **Canceled**.
