How would you go after this client base?
The company has their tagline "website design by ..... " in their footer, so we can use Google to some extent, but what other options would you pursue if you were in our shoes to get this client data to make contact and see if you can help them migrate to our services?
Is there a way to scrape for email addresses using IP addresses? Any other legal ways that anyone can suggest that can help us find and contact this client base? Any feedback appreciated!
