Digital invitations: the email subject line that gets opened

You're sending the wedding invitations and you type "Fiesta!" in the subject line. Three days later your cousin texts you to ask the date. The email arrived. It just never got opened.

For digital invitations, the email subject line does more work than anything else in someone's inbox. There's no envelope on the hallway table and no card on the fridge. The subject line is the entire first impression.

The email subject line for a digital invitation does the sorting

Picture the person on the other side: twenty emails a day, a phone buzzing in a coat pocket. "Party!" gives them nothing to sort on. "Marta and Luis's wedding · 14 June · 19:00" answers the two questions they have before they tap: what is this, and do I need to do something about it. All caps and three exclamation marks read like a promotion. A wedding reads like news.

• Wedding of Marta and Luis · 14 June · 19:00, Barcelona
• Nico's birthday: Saturday 8, 17:00, at the grandparents' house
• Julia's christening · 21 September · Santa Ana Church
• Office dinner: 12 December, 21:00, Albor restaurant

What fits before the first cut

On a lock screen you get a few words and then an ellipsis. Put the event and the date at the front, never at the end. "Ana and Diego · 12 October · 19:00" arrives complete. "Wedding of Ana and Diego, ceremony, dinner and dancing from seven" gets chopped in the middle and tells the reader less.

If you're writing in two languages, write the subject line in the language your guest actually reads, rather than running it through a translator. Send The Joy's invitation content can be set per language inside the same page, so the email and the page match. And when you drop the link into a group chat, keep the same words you used in the email. Changing them halfway makes people wonder whether it's the same event.

The subject line opens the door. The link does the rest.

One language per subject line, one link behind it

An email with a PDF attached makes people download a file and hunt for it later. A link opens in the browser on their phone, with no app to install. Because the link stays the same when you edit the time, the venue or the map, the subject line you wrote is still correct after any change.

From email to reply, without chasing anyone

The email announces; the confirmation happens inside the invitation. Replies land in an ordered list on the same page, and you set the RSVP questions yourself. Nothing gets lost in a chat thread, and nobody has to reprint an envelope because the address changed.

Write your subject line around the event and the date, email it to yourself first, and let the link handle everything else. You can try a design for free and edit the cover; when you buy, every scene of the invitation unlocks for €29.99 as a one-off payment.
