How much should I charge per email sent?

Hi,

I have a client for whom I have recently made a website and now he wants to promote his services in a specific area by sending B2B emails. My task would be to find the emails of companies in the client's area of interest and send a message to promote his services.

How much should I charge per email sent, including gathering emails, etc.?

I would appreciate your suggestions.

How much would you pay yourself if you were in his shoes? Take that amount and add a bit more to it.

Get a linkedin premium membeship and start scraping not only company websites but also employee websites. Double charge for that and don't be shy to keep prices high. Remember, these are essentially B2B leads.

Thank you for great ideas. I will do that.
