Hi, ​@mjm1997!

At the moment, there's no way to trigger an automation within this scenario. Unless they send a keyword, nothing happens.

BUT… you could set a default answer flow up. It would trigger on every message send to your account that isn't triggering another automation.

Take a look: https://help.manychat.com/hc/en-us/articles/14281159586588-Default-Reply-in-Manychat

Hope this helps!

i have the same situation, users do not send keywords and sometimes dont follow the default reply...

Try setting the default reply with a Data Collection block. You can set an Option list and a default reply in case some user send anything different.

It's not the most flexible way, but it should work to sort the conversations...
