Frequently asked questions
The pen, the proof, your handwriting, the price, and how it connects to your tools.
About the product
Is it a real pen and real ink?
Yes. A pen plotter, a machine that holds a real pen, writes every piece in real ink. It is written, not printed. The pen follows a handwriting font with natural variance. Our machine does the writing; it is not a person with a pen.
What does a proof look like?
A render of the exact card and envelope, with your message and the merge data from your list filled in, as it will be written. You review it, and nothing is written until you approve it.
Can I use my own handwriting?
Yes. You write a sample, and we generate a font matched to your hand from it during onboarding. That takes minutes and is included. If you would rather not, you can pick one of the fifteen handwriting styles that are ready to write today.
What does it cost, and where do I see it?
There are three monthly plans: Essential at $399, Professional at $949, and Enterprise at $2,199. Per-piece rates for greeting cards, postcards, and letters are listed for each plan on the pricing page and billed monthly based on what you send. There are no setup fees or long-term contracts, and you can cancel anytime.
Which integrations does LetterCircuit have?
LetterCircuit connects through the REST API, Zapier, Salesforce, HubSpot, and MCP for AI agents, or you can upload your recipient list as a CSV.
Does anything mail without my approval?
No. Every batch is reviewed and approved before it mails, and nothing is written until you approve the proof.
How do I get started?
LetterCircuit is hand-onboarded for now. Join the waitlist with the Get Early Access button. Self-serve comes later.
For real estate and mortgage teams
Is handwritten mail compliant for real estate and mortgage outreach?
LetterCircuit is not a compliance service. Fair-housing, RESPA, and state-specific rules are the customer’s responsibility. What we provide is a human approval step before any batch mails, so nothing goes out unreviewed.
Can I send a large batch of listing-anniversary letters at once?
Yes. Listing anniversaries are recurring, date-driven campaigns, which is what a LetterCircuit campaign is built for. Send the list, approve the proof, and we write, inspect, and mail.
What list do I need to supply for a listing-anniversary campaign?
A CSV of past-client name, mailing address, and transaction-close date, exported from your CRM or transaction-management system. We validate it for required fields and address deliverability before anything is written.
Can the same campaign structure serve both agents and mortgage loan officers?
Yes, but the message angle and merge fields differ (listing date vs. loan-closing date), so each role gets its own approved template inside the same campaign structure.
How do you measure whether a listing-anniversary letter led to a referral?
You pick the measurable action at scoping. Common choices for this vertical are a dedicated callback line or a reply card; whichever you choose is defined before production starts.
