Pitchbox Email Personlisation / Data Entry

I have a list of websites, and email addresses associated with those websites.

I need someone to go through the list, delete email addresses that are not relevant to the website, and find the names of the email addresses which are relevant to the website.

This will be done via a tool called Pitchbox. If you have experience with Pitchbox, that would be beneficial.

This jobs is a test run. If this goes well, then I will be looking for someone to do this on multiple projects. Which will provide a larger budget in total for the freelancer.
