100 Birthday Email Subject Lines to Inspire Your Own

Sending your customers an email on their birthday is a nice personal touch to your email marketing that strengthens the customer relationship. Having great birthday email subject lines is essential to ensure trust with your customers.

It’s also a great way to generate additional sales throughout the year without giving away too much margin all at once. 

But sending birthday emails is only half the challenge. The other half is getting customers to open them. 

That’s where subject lines come in. 

When one-third of your email list decides whether to open an email or not based on its subject line, coming up with the right subject lines is vital to improving your open rates.

That’s why we’ve put together this list of 100 great birthday subject lines top brands have used in the past. Feel free to use them as inspiration for when you’re coming up with your own.

Instead, you can send it a few days in advance to get in ahead of others.

Examples mentioning a special birthday offer

Including an offer in your email campaign is a great way to make your customers truly feel special on their birthday. 

And if you decide to do this, you’ll also want to mention it in your subject line to help boost open rates. Just like the examples below have done.

Asking for a customer’s birthday

Of course, to send your customers an email on their special day, you first need to know when their birthday is. 

If you don’t know this, one way to find out is simply by sending them an email and ask them when it is. If you opt for this strategy, you’ll want to give the email a subject line similar to the examples below.

• Happy birthday! Oh no. WAIT. – Boden
• Happy birthday, maybe? – Evite
• Sign up to receive a birthday treat. – Garnet Hill
• When’s Your Birthday? – Kendra Scott
• Happy Birthday, {NAME}? – Minnesota Timberwolves
• Want A Birthday Gift? – Splendid

Obviously, your subject line is only an (albeit important) part of your birthday campaign. 

To ensure your campaign reaches its full potential, you’ll also need to think about the contents of your email. 

Luckily, we’ve also put together a guide on birthday emails that covers everything you need to know from asking customers when their birthday is, what offers to include in your emails, to cultural sensitivities to be aware of.
