Looking for meetup group admin email ID's? Does anyone know how to get a list of emails from major cities?

Which specific major cities are you targeting across the USA, EU & UK?

• New York, NY San Francisco, CA Chicago, IL Washington, DC Palo Alto, CA Boston, MA Los Angeles, CA Mountain View, CA Seattle, WA Austin, TX London, GB Toronto, CA Tel Aviv-Yafo, IL Paris, FR Vancouver, CA Sydney, AU Melbourne, AU Bangalore, IN Berlin, DE Amsterdam, NL Stockholm, SE Oslo, NO Pune, IN Singapore, SG Madrid, ES Brisbane, AU Hyderabad, IN Auckland, NZ Barcelona, ES Budapest, HU

What would be the keyword/s to be used as input search criteria for extracting the required data?

• I am not sure about the keywords. I am looking for meetup group admins with less than 2000 group members

What would be the key data attributes in terms of output file apart from the admin email IDs?

• Group Name | Group Admin Full Name | Email | Group Members | City | Country

What would be the frequency to extract the data like Daily, Weekly or Monthly basis etc.?

• This data is for a pre-launch of a product in the same space. So it's a one - time job.
