Here's what I noticed!
1) It was a generic email written to everyone - they didn't even address me by name
2) they asked for my resume/headshot/showreel, but they didn't even check my website and realise that my headshot, resume and showreel were already there.
If I am looking for an agent to represent me, I would prefer someone who is GENUINELY INTERESTED in me. Rather than sending a mass email to everyone who you could get your hands on, try researching a few people, seeing who you can really help, write them a personal email and show some interest in them.
If only you did this, I probably would have signed up!
TRY AGAIN NEXT TIME!
Hint for actors:
DO NOT write generic emails to casting people sending them junk. Say something meaningful and show that you are interested in them. Talk to them on a personal level. No person likes being treated as a 'business'.
