Hello,
What is a whitelist MTA (Mail transfer agent )?
-> A software that allows to transfer electronic mail messages from one computer to another using SMTP to the inbox folder not to the spam folder.
Like spamhaus ,which marks the host or ip as blacklist .
Alright, let's get to the point .
We can get the confirmed coin buyers from the blogs (Twitter and bitcoin)
My major projects have web scraping in it using php, puppeteer ,headless chrome and most important JS injection.
My prior project in freelancer.com was the same skill set but for instagram to get 10M+ followers in 30 minutes.
About 3rd party email verification ,yes, that you can perform for verification of the data.
I am looking forward to work with you and the project success.
Thanks
