We all want to create a magical birthday experience for our little ones. Our online birthday invitations make that job a little easier, giving you one less thing to worry about ahead of the big day. If your child is mad about mermaids, choose from our exciting range of mermaid party invitations to send to guests. You can send online invitations quickly and effortlessly on behalf of your little mermaid to all of their friends to create excitement and anticipation for the magical event.

What to write in your mermaid birthday invites

When you create an online mermaid birthday invite, you’ll be prompted to complete the template with an event date and location. Our templates are super easy to edit, and you can be sure that you haven’t missed out on any important information! If you want to get creative, there is also space to add your own text and images.

What details should I include on a mermaid birthday invitation?

On your invitation, make sure you’ve included the name of your child, and what age they’re turning. Include the time of the event, the location details, and your RSVP deadline. If the theme isn’t already obvious by the beautiful mermaid design on the invitation, let your guests know with a sentence or two!

When to send your mermaid party invitations

Our online mermaid birthday invitations are quick and easy to create. We recommend sending your mermaid invitations between three and five weeks before the big day, to give your guests time to check their calendars and RSVP. If you choose to send them earlier than this, no worries! Paperless Post makes it easy to send out helpful reminders to guests a week or two before the event.
