I am iOS developer so dont know very much about sending email.
ok here i tell you short story . From last 3-4 years i have been collecting emails from different sources . . . extracting emails from my /friends /relatives email accounts.Some of the list i have purchased from one of my client.
So if i combine them all they are aprox 80000 emails. and i know very well that from 80k at-least 50k are 100% ok emails because i know its source where i took.
So here is my question . . I have listen very much about affiliate marketing and i want to do that. and i have tried from MailChimp . When i import less then 300 contacts then it works very good and all the things work perfectly but when i import greater then 300 then MailChimp say the emails are not valid . i have tried multiple mailchimp accounts to check this thing .
What should i do. . i have the list of valid emails but my doors seems close to me to earn any money..
