By now, most of us have received a wedding invite or two online; but if you've ever thrown a party and realized that you forgot to invite a couple people who aren't on email or Facebook (I have, ooops!), you've probably also wondered whether that might be a problem for those throwing a wedding. Turns out that it is. 

So while many couples decide that it's faster, easier, less time-consuming and certainly eco-friendlier to invite the majority of people on their list to their wedding via an online invite, there are people who can get left out of this system.

Mariko Fritz-Krockow told that when she sent invites to her wedding in 2011 via Eventbrite, “There were a couple of people who were incredibly confused,” she said. “They didn’t understand that the email was an invitation. They had no idea what we were trying to do. We had to call them and ask them if they were coming and they said, ‘yes,' but then asked where their invitation was. Even my mother, who is tech-savvy, didn't know she had to had to RSVP electronically.”

Clearly, this can be a conundrum for couples; on one hand, the envelope-stuffing time, the expense and the waste of printing and mailing multilayered envelopes is wasteful (who but the couple really keeps a hard copy of a wedding invitation, after all? As a guest at a dozen weddings so far in my life, I know I've recycled them all). But you don't want to insult older relatives who won't feel officially invited until they've received some creamy, frothy, calligraphied thing in the mail. 

But fear not — there is a way to have it both ways. Some of the 'paper-free' invite companies are now offering a way to do both types of invites, with print-on-demand options (so you can, say, send 75 pretty, designed invitations via email, and 15 on paper). So you can have it both ways. 

Even the cofounder of Paperless Post, James Hirschfeld, understands the tough spot modern brides and grooms are put in — and the need for an appropriate response to it: “The reality is that we live in a hybrid world of print and digital. No one lives their life totally online or totally offline, so it’s important for us to serve digital and paper needs,” he said. 

So if you are sending out invites, keep in mind that you now have options to fit everyone on your list so you can have keepsakes and keep paper-lovers happy, and cut down on waste and costs too.

They might be good for the environment, but with virtual invites, there are some downsides.
