Brett Wilson LLP Solicitors (M): Over 99.9% of Our E-mail is Self-Marketing, We Send You 3.5MB E-mails for Less Than 1KB of Text
They clearly lack IT skills/IT personnel:
That's about 2MB per plain text sentence (there's no formatting).
There are no attachments there. They just sent like 14 MB of E-mails to transmit a grand total of eight sentences via Microsoft. Everything they use is Microsoft, even storage ("privileged" but shared with Microsoft) and authoring (Microsoft can see everything they type in real time).
Why would tech people entrust legal matters to such people? They don't know the very basics. █
