Hello,
I work with a bulk sms and email marketing company which deals with a huge amount of data. Their primary work is to provide bulk sms services to people and businesses who require them.
I could provide you with a list of around 6000 emails, these emails would be primarily be indian and I could provide you more but that would require additional charge.
If you are interested then please feel free to contact me.
Thanks and Regards
Akshay
