I'm quite direct during parents night.
I only really talk about literacy and numeracy as, in my experience, no primary aged child's parent wants to know how they fare in RME etc.
I summarise their progress, identify any areas we are working on together, suggest ways in which the parents can help, give an overview of behavior throughout the year/term and then ask if there are any issues.
I leave out the most recent literacy and maths jotter for parents to look at before or after the meeting.
I let parents know they can arrange a meeting with me after school and we can discuss any further issues in depth.
I find that I only go over when parents derail the conversation. I've had one talk about her recent dentist visit, one about her nursery childs poo, one about how school was in his day, one about their work etc. I tend to nod along and when a lull occurs I politely but firmly say "nice to meet you, don't forget I'm around at the end of the day if you want to speak to me about anything else. Little Bobby's work is outside if you'd like to look before you go".
I'd also never give out my professional email address. I do not need parents houding me when they are capable of writing a note or asking to speak to me. That email address is to communicate with other members of staff, not to answer all parental queries. That email address is also only accessed in personal time as there is no time during working hours, I'm not spending my personal time replying to parents.
