A: Yes, it's absolutely possible to engage with individuals who've interacted with your Messenger, similar to how you'd send out a newsletter in email marketing. There are a couple of ways to go about this:

Sequence Messaging: This is akin to drip campaigns in email marketing. Based on certain triggers or after a specific time lapse, you can automatically send follow-up messages to those who have engaged with your Messenger. This ensures continuity in conversation and can be especially useful for nurturing leads.

Bulk Messaging: This allows you to send a message to a large group of users all at once. It's perfect for announcements or updates. However, as you rightly pointed out, it's important to keep in mind the 24-hour interaction window to ensure compliance with platform policies.

Hope that clarifies things! If you have any other questions or need further assistance, feel free to ask. Happy messaging! 😊
