The names you add to your recipient list will automatically populate on the front of the envelope. If you leave the "Name" field blank, your event title, or the subject line for non-RSVP cards, will appear instead.
If you're hoping to change the font and color of the text on the envelope, the steps to do so depend on whether you are designing a V1 or V2 Card. To tell what kind of Card you are designing, look for the V2 icon in the lower left corner of your page, as seen here. If you don't see V2, it's a Legacy card!
V2 Card
From your Card's Create/Edit page, click or tap on the envelope to select it, and then choose the Flip icon to view the back of the envelope.
From there, you can tap or click on the text to select it, and choose the font of your choice from the Envelope fonts panel that appears.
There is not a way to choose a different color for the envelope font at this time — we hope to add this feature in the future!
V1 Card
From your card's Customize page, you can can edit your envelope’s font and color by clicking the sample text on the front of the envelope. A menu will appear on the left with two sections: Typefaces and Colors. Click on either menu to see the options available.
