Dear Dr Rollock
Thank you for your time today. As discussed, the Advertising Standards Authority is currently carrying out a project to explore its position on gender stereotyping in ads. One of the key aims of the project is to seek views and gain insight from a range of stakeholders. We would be grateful if you could share our press release and call for evidence with colleagues who you think might hold relevant research or be interested in the subject matter more generally. We are currently in the scoping stage of the project and although the press release states the deadline as the end of June, at this stage we expect that any research received by 22 July would be in time to help inform our public research brief. Research submissions received after that would not be able to inform the scope of the public research but of course would still be very welcome.
We are happy to receive research, commentary and questions to this email address (firstname.lastname@example.org).
