Trello plus contalist (or another contact management software )

[Archie]

Hello 👋 all ,

I am looking for a way to send sms blasts to employees or employee groups

example to all employees or managers or admins

I just started exploring contact list and that seems to do the job

What I am not clear on is how to send sms blasts to a groups directly from Trello (+ contalist) without having to leave the boards

I used power ups and integrated trello and contalist , but from Trello I am able to send sms messages only to one or more contacts and not to a group or segment from contalist 

am I missing something ?

TIA 🙏🙏
