So I just signed up to LingQ and I think it looks like a great site, really promising and I’m hoping it can help me to improve.
Just a bit of feedback, I deem 4 e-mails in the space of 20 minutes to be excessive. I don’t mind a welcome e-mail but I don’t appreciate the spam about referring friends and earning money.
Maybe you could consider condensing it all into a single e-mail?
