Cold Email: Is there something like swipefile.com for email marketing?

Hey folks!

We're writing a lot of emails and need inspiration. I'm not looking for fill-in-the-blanks templates, but inspiration from successful marketers. I thought there has to be a website that gathers famous newsletters but I couldn't find it. I already subscribe to a few obvious ones and have them sent to a folder but thought maybe there's a more convenient way.

thanks!
