With House of Pitch you can sort pitches by clicking "Connect" (and it goes to your inbox) or "Nope" (a sender receives a notification, and this means no, no follow-ups, no more bugging).

Only a one-liner and a short description. No misspelled names or "Hope this email found you well" openers.
And don't be afraid of clicking Nope. "No" answer is better than no answer.
