I have a wordpress system built for my wife's business, all her client details are stored there, it's all opted in data of current clients. She can reach out to these clients via SMS and email, but ideally she would like to contact people via facebook messenger, to send a message to (offers etc.),
All recipients would be people who have liked our page and interacted with us on messenger previously.
Is there anything out there that can be used to automate this, without having to manually type/send every message?
Thanks if you can help.
