e-Mail adress check on internet

Job ID: 34801943

Budget: €30 – €250 EUR

I have a list of email addresses. I must have checked whether these e-mail addresses can be found on the Internet, if they are found I need the link on which page they can be found.
Example:
anfrage at fleissigesbienchen.de - Link on: https://fleissigesbienchen.de/Impressum-fleissigesbienchen

If this email address cannot be found anywhere on the Internet, then the field must be filled with NULL.

I will provide an Excel file with the email addresses. I would like to have a good and reasonable price for this work from you. I don't want to renegotiate anymore. Questions like sir, can you please give me more money I will not answer. The scope of the work is clearly defined. I will accept the offer where the price is cheap and where there are good reviews from other clients.
