Account-based direct mail for B2B revenue teams
Build physical outbound into your revenue motion. Personalize and send every piece from one place, integrate it into existing workflows, and measure the pipeline it creates.
Why paper works
The inbox absorbs another sequence without noticing. A good piece of mail gets opened, read, and left on the desk, which is exactly where your rep’s call finds it. Physical isn’t nostalgic. It’s under-contested.

The platform
A print API gives you an endpoint. Sincerely is everything around it: the writing, the orchestration, the operations, and the number at the end.
01 · Writing
Every draft starts from what the account actually did: the round they raised, the roles they opened, the product they shipped. Every fact carries its source, and nothing prints until a rep approves the words.
Maya is a sample. Hover the highlights to see where each claim comes from.
Dear Maya,
Congratulations on the Series B. I read the announcement, and then the eleven open sales roles on your careers page. New reps mean new pipeline targets, and most teams find out mid ramp that the outbound stack was sized for the last stage.
If that’s already on your mind, I’d like twenty minutes before your new reps start in June. The QR below books it, and either way, no sequence follows this letter.
Sincerely,
Dana Reyes · Account Executive
02 · Formats
Postcards, letters, handwritten notes, and gifts, at published per-piece prices. You contract with no print vendor.
every provider → one interface → one invoice
03 · Orchestration
Sequences trigger on what your CRM already knows: a funding round, a renewal window, a deal gone quiet. They run to a cadence, and eight campaign types cover the funnel.
a sequence for every segment
04 · Measurement
QR scans catch direct response, matchback ties meetings to mailed accounts, and account-level holdouts measure lift. Evidence and inference, labeled.

Fulfillment

Weak facts stay flagged even after approval. Nothing prints until someone here approves the words.

Launch a pilot to your top accounts: research-backed pieces your reps approve, follow-up timed to delivery, and an account-level holdout that reports what the channel actually created.
Setup takes an afternoon. Delivery takes days, because paper travels. The report takes a sales cycle, because pipeline does too.
