Help with Automation Ideas - 10k posts per month / Half Automated already

Hi There,

I'm the admin of a buy and sell group which has 10k ads posted per month. I already have a system where I am automatically posting these ads onto my classified website.

But I would like to be able to message these people individually. So is there software in 2020 that actually works and can do this? Or is it a full custom script and trial error?

I do have two pages also, one which I can make admin of the group and use for messaging.

Ideally I want this to look as professional as it can be, rather than having 100 fb profiles messaging all these people.

Maybe someone could point me in the direction of a BHW member who has a good reputation with this sort of thing?

Full custom script, but there is a high chance of being flagged if you are going to be messaging EVERYBODY that posts from one admin account.

I'm not entirely familiar with how buy/sell groups function on Facebook - but do you have access to any of their email details? If so, you could potentially grab those and send an email. Lower visibility but less risk.

Is it possible to do something like this with some form of messenger script?

I was originally thing of using maybe 20 fb accs, but it doesnt look very professional from the websites point of view.
