Social and technical Business Email Researcher

General information for the business: We have an Online Database
Industry: Internet/Software
Geographical areas: Global
Data to include: Hi.

We need a email/contact researcher.

We have a list of 561 business emails, including company contact name and company name. These emails failed while validating through bulkemailchecker, we excluded catch all server issues, but included Dupe, not existing, invalid dns, invalid format, internal blacklist emails.

We want you to research the correct mail adresse, through:
- check/ correct the spelling (wrong spelling in the domain)
- researching the correct email:
1) does the person still work there? linkedin, company website or even call (via skype)
2) google etc search
3) guess validating the email address e.g. through hunter.io

The list needs to be extended with the correct emails address and/or a comment, like:
Does not work at company anymore.
Link to Email Addresse found via Google.

Best,
David
