We all have ‘em. Emails that we’ve written but never sent; confessions of unspoken crushes, reconciliation with heartbreak, apologies you couldn’t bring yourself to send– with cursors hovering over and eventually retreating from the send button.

To celebrate this month’s theme of Taboo, MailChimp and CreativeMornings want to see those emails.

We’re collaborating on a campaign called The Inbox of Forgotten Emails and inviting you to share your most horrific, funny, weird, or embarrassing emails and drafts. We’ve built a site to collect and curate emails like love letters, “just following up,” rejections, and convos with old bosses. Names, of course, can be anonymous.

So dig to the bottom of your inbox or drafts folder, and hop on over to The Inbox of Forgotten Emails to submit yours today.
