Sending Automated Birthday Cards to Customers (Without Data Collection)

Most DTC brands aren’t sending birthday cards. Not because they don’t see the value, but because the data’s a mess, and they probably don’t have a direct mail partner they can rely on.

If you don’t have a loyalty program collecting birthdates or a CRM that tracks customer milestones, it feels impossible to personalize at scale.

PostPilot solves that. 

You can send automated, personalized birthday postcards to your customers—even if you don’t have their birthdate on file.

No manual data pulls. No extra software. Just a crazy easy way to increase retention and customer lifetime value using one of the most effective touchpoints out there.

Birthday Cards Still Work (Maybe Better Than Ever)

Birthday postcards in the mail feel different. 

They’re timely, tactile, and don't scream “promotion.”

• They’re tactile. Birthday emails are great, but if you get a physical happy birthday from a brand, even if it IS automated, brands that send them show customers they’re going the extra mile.
• They tap into positive emotion. They trigger memories, sentiment, and surprise. Especially if you’ve automated handwritten cards.
• They make customers feel remembered. It’s a break from the constant pitch.
• They prompt action. A card can drive a purchase, a share, or even a photo posted on social.
• They stick around.

Postcards that don’t look or feel like a marketing flow tend to perform best. A birthday message landing right before someone’s big day hits that sweet spot—relevant, welcome, and personal.

You Don’t Need Birthday Data. We’ve Got You Covered.

PostPilot has proprietary access to birthdate data on millions of U.S. consumers. You don’t need to ask for it. You don’t need to collect it.

That means…

• No loyalty program needed.
• No customer input required.
• No delays. You can start sending immediately.

We match your customer list to our database of known birthdates. Then we handle the rest. Cards go out automatically, arriving just before each customer’s birthday.

It’s a simple plug-and-play retention tactic that works for any ecommerce brand, regardless of your tech stack.

Two Examples of Automated Birthday Cards at Scale

Red Land Cotton

This Alabama-based bedding brand is known for quality that’s made in the U.S. They focus on creating lasting connections with customers who appreciate craftsmanship and heritage.

When Red Land started sending birthday postcards through PostPilot, they saw consistent repeat purchases from high-value segments. And they didn’t have to lift a finger to gather extra data.

The cards were simple but personal, timed to arrive a few days before each customer’s birthday. Just thoughtful enough to feel special, but smart enough to scale.

The results were stellar: a 9.02x ROAS.

Plum Deluxe

Plum Deluxe started as a community, and they brand they built is centered around sincere, personal, thoughtful experiences.

To add another layer to those experiences, they used PostPilot to send handwritten birthday cards to customers, automating what would otherwise be a time-consuming retention play.

Plum Deluxe's Dir. of Marketing Communications, Ciaran Heast, even told us, "When we saw that PostPilot had the handwritten birthday card feature, we thought: “This is so perfect for us.” This is our ethos, but we can't handwrite that many birthday cards. Our hands would fall off!"

The cards drove real results: a 9.6x ROAS! 

By making the gesture feel human, even at scale, Plum Deluxe turned birthdays into high-converting touchpoints.
