Hey guys, Sid here! I've been working on a web application where users can - Upload a list and bulk verify them ( list gets processed in chunks and you can simply and check later, they gets tagged as "valid", "invalid", "syntax", "catchall" Clean the list and send newsletter to them using your own template or by adding your own messages Track the open/clicks via the dashboard I am looking for beta testers who can help me drive this product in right direction. If you find this interesting, just reply to this thread and we can take it from there. Looking to focus on; just bulk verifications, email filtering and Exporting. Something like neverbounce. I can create beta tester account details, whoever seems interested - I will be taking maximum 10 beta testers.
