What guests see with the Space Invaders theme
This page wears the theme just as your party page will. The same art and colors carry through every email you send.
The invitation email
Subject: โ๐ You're invited: Arjun's 7th Space Missionโ. The theme art sits at the top, and the message opens: โA bright birthday mission is almost ready for launch, and we'd love to have you on board for Arjun's 7th Space Mission.โ
A matching RSVP page
Guests open a party page in the same art and colors, see the date, time, and place, and reply Going, Maybe, or Not going. Every reply lands in your guest list.
Reminders and thank-yous
RSVP reminders, party-day reminders, and thank-you emails you send from Kiddobash keep the Space Invaders look. You can change the theme later from your event page.

- At a planetarium or science center, name the entrance or room and say whether adults need their own tickets.
- For an evening stargazing party, give the end time and suggest warm layers.
- If the activities suit a certain age, mention it so parents of younger siblings can plan.
