Wedding invitation email subject lines that get opened
The subject line decides whether your wedding invitation gets opened or left in the inbox. Here's what to write, how many characters, and how to fix a change without resending.

It's 7:40 on a Tuesday, you're on the train, and you're scrolling your inbox with one thumb. Twenty emails. One says "Hi" from a name you're not sure about. Another says "A little something". A third is from the electricity company. Somewhere in that list is the subject line of your wedding invitation email, and right now it's competing with a gas bill and a gym newsletter for the same two seconds.
That's the whole problem. The subject line is the only part most guests read before deciding whether to open. Get it right and the envelope opens itself. Get it wrong and you'll spend the next month chasing replies from people who never saw the date.
The wedding invitation email subject line is the envelope nobody sees
On a locked phone screen, a guest sees roughly 30 to 40 characters of the subject line, next to your name. That's the whole shop window. So it has to do the job the handwritten name on an envelope used to do: identify the event in the first three words.
- 'Marta and Luis are getting married' does the job. 'Invitation' on its own doesn't say whose wedding it is.
- Keep the order: who, what, when. 'Marta and Luis - Wedding invitation - 14 June' is clear without opening anything.
- If guests live in different countries, add the city at the end: 'Marta and Luis - 14 June - Seville'.
- Don't start with 'You're invited to...'. It makes people open the email just to find out what it's for.
Put the names before the decoration
Start with the actual names, not the formula. 'Lucia and Andres are getting married on 14 June' puts the useful part where the eye already is. On a phone, anything past the first line gets clipped.
If guests are spread across cities, the place earns its space just as much as the date. 'Marta and Luis - 14 June - Seville' stops someone emailing back to ask whether this is the wedding they think it is.
If the subject line would work just as well with another couple's names in it, it isn't doing any work yet.
Capital letters, emojis and other alarm signals
'MARTA AND LUIS'S WEDDING - OPEN NOW' shouts. Spam filters and guests read shouting the same way: like a promotions folder, not a wedding. One emoji is plenty, and only if it means something - a ring, an olive branch. Three hearts in a row turn an invitation into a newsletter. Urgency words do the same damage: 'LAST CHANCE' and 'REPLY TODAY' make a happy date sound like a deadline.
Your name in the sender line does half the work
Send from a real address, not a 'noreply'. A guest who wants to ask about the dress code should be able to hit Reply and get an answer. With a long guest list, use BCC or share the link one at a time; nobody wants their email sitting next to sixty others. Sign it as 'Marta and Luis', not 'wedding organisation'. The subject line and the sender are the same introduction.
If the ceremony moves from 1pm to 12:30, the useful subject line is 'Update: Marta and Luis's wedding, 12:30' - clear, no apology needed. A digital invitation keeps the same link, so you can edit the time, the map or the dress code and guests see the updated version without a second email. One link, correct every time someone opens it.
