Your invitation should get your guests excited as soon as it lands in their inbox. There are definitely some things to keep in mind before sending out your first blast of invites, so here are a few of our very best tips:

Case of the Mondays. Yes, it’s a thing.
Everyone knows that Monday is the worst day of the week. So, it only makes sense that Tuesday is considered the golden day of the week. At Splash, we found that emails on this day have an overall open rate of about 18% – higher than any other day.

Looks do matter.
When designing your party invitation, make sure the design is consistent with your event site. Invitees are 15 times more likely to register for the event if the overall look of both the invite and event site are homogeneous.

Timing is everything.
On average, we spend a total of 9 minutes on email via mobile device every day. Of the said 282 minutes on our phone, that’s only a whopping 3.19% in email. Reality check: that’s not a lot. So, sending your invite at just the right time actually matters. We have found that the optimal times to send invitations are 6AM, 10:30AM, and 4:30PM.

Consider phone vs. desktop.
45 percent of all emails are viewed on mobile phones, so the way your invite looks on a phone screen is crucial. If you have to pinch and zoom, or scroll to the right to view the entire invite, then it’s time to go back to the drawing board. It’s also important to keep in mind that on smartphones, only the first 38 characters of your subject line can be seen before opening the actual email. Make your first line a good one!

Creativity stands out.
Do you remember the You’re Invited! invitations from 1995? Yeah, we don’t either. Emails with “you” in the subject line are opened 5% less than without. Try to get a little more creative than just simply stating the obvious in the subject line of your invitation. For example: “Time to get down” is a great opener for your 90s dance party. And “Grab a cup, pet a pup” is the perfect way to invite guests to your puppy-themed breakfast event.

Be fun or go home.
Let’s face it: no one wants to go to a boring party. And they certainly don’t want to receive a boring party invitation. GIFs are the perfect remedy. Just search for “dance” or “party” or “celebrate” on, and you’ve got a goldmine of party-related GIFs. (This one is my favorite.) Pro-tip: If you’re using Splash to design your event page or invites, adding a GIF is super simple to do.
