I am a beginner marketer to promote the project (proofy.io)
This online service is designed to check the validity of email addresses. The customer receives a quality check email addresses at an affordable price. From concurrency makes us different price, an individual approach to each the client and scan speed.
You can probably cut heaps out of your list with a simple PHP script (proofy.io) that queries the mail server and checks if the address is deliverable. Some mail servers won't respond properly to this but enough will to give you a better bounce rate. You could also do some more things like checking if the domain is registered and if it has MX records. If you want I can do this for you and customize a script that will work with other providers that do not respond correctly to the above. Please send me a PM if you would like to discuss it.
