Simple Process
Getting started is simple
Send us your list and what you want to say. Same message for all, or unique, it doesn't matter to us. That's it. We handle the rest.
A real pen on premium cardstock, written by our proprietary handwriting machines. Every note has natural imperfections and is reviewed for quality before it goes out.
Not their inbox. Their actual mailbox. The one they open every day without a filter, a delete button, or a spam folder.
Need to keep recipient data in-house? We can work around your preferred process.
Your Warm List
The people worth staying in touch with are already in your world. Here's how to make sure you actually do.
Most professionals have hundreds of people they've already built a connection with. Past clients. Referral sources. People who went quiet but never forgot you. That relationship is worth a lot more than most people act on.
You already know the problem. Emails get ignored. A phone call every six months feels forced. So the list stays cold and the relationship fades. Not because they forgot about you, but because nothing stood out enough to bring them back.
A handwritten note shows up in their mailbox, not their inbox. It doesn't ask for anything. It doesn't need a response. It just reminds them that you're real, you're thoughtful, and you're still around. That's usually enough to get a reply.
