right now all I have is email ids

If the lawyers are not using the domain of their law firm are you sure you are dealing with real lawyers and not scammers? If it is the domain of their lawfirm then you should be able to get contact information off their website. Something is off about all of this.

No, I mean I'm using a email service on top of my own domain, and the people I want to contact only have their email ids listed online and I want to have contact via email prior to having a voice call or video call for which I need a two way communication via email.

Belive it or not, that's my current situation
