Let agents send real handwritten notes for you

QX picks the card, writes the message in your voice and sends it through Handwrytten—so the people who matter to your business actually hear from you.

@QX Who deserves a thank-you note this week?

Sarah Chen at Northwind just renewed for year two, and Marco at Lumen closed his first deal Tuesday. I've drafted warm notes for both on your branded card. Want me to send them?

Stop letting good intentions die in your to-do list. Hand the handwritten touch to an agent.

Gratitude

Thank-yous that actually go out

Every new customer, signed contract or referred lead triggers a personal note—drafted in your voice, mailed on your card—so appreciation lands in a mailbox, not a draft folder.

Retention

Stay top-of-mind with the people who matter

Birthdays, anniversaries, milestones and quiet accounts all get a real card at the right moment, automatically—turning your best relationships into ones that keep coming back.

Outreach

Cut through the digital noise

When email isn't enough, an agent identifies the right targets, writes a thoughtful note and sends a physical card—the kind of touch that actually gets a reply.
