Introduce a list of queries (the more better) and let Mail Crawler make the job.

Mail Crawler navigates on related webpages searching for public email addresses, so all the crawled emails will be potential for the introduced queries.

Very easy to use! Just import queries from an Excel file or type them manually. Tap the "Crawl" button and wait for the results.

You can copy the result mails or export them in an Excel file to your device.
