A digital surprise party invitation on a tablet

Not to toot our own, but — toot! toot! — we’re sort of professional surprise party planners. Detectives envy our secrecy, our lips are always sealed, and our surprise party invitations — they don’t leave a trace of evidence.

That’s right. Your guest of honor can dust for fingerprints and search our (snail)mailboxes with a magnifying glass, but our surprise invites will go undetected. Why? Here’s a bit of not-so-classified information for you: Our paperless invites don’t use RSVP cards, address labels, or stamps. No paper, no evidence.

So put us under the microscope all you want. These surprise party invitations won’t be found.

Greenvelope Can Keep a Secret 

Now, persuading each and every guest to keep their lips sealed? That’s where we bow out.

While we can’t ensure that one of your co-conspirators won’t blurt out the big surprise, we can ensure that the honoree won’t find evidence prior to the party. With Greenvelope, all invitations are sent directly to your guests’ inboxes.

There’s no secretly-stuffing envelopes, guarding mailboxes, or hiding address labels. Just quickly — and discreetly — customize one of our surprise party invitations according to your needs, upload your guests’ email addresses, and walk away from the computer.

If your guest of honor is known for being quite the detective, we assure you that we won’t leave evidence behind. But when it comes to face-to-face conversations, all we can advise is … try to avoid eye contact.
