What to write, how to follow up, and how to judge results at tiny volume. Source: https://trysincerely.com/playbooks/founder-led-sales The play: you, the founder, send about 20 letters a month to accounts you picked by hand. Each letter is written for one person, signed by you, and followed up by you. Run it when you are the sales team, your deal size justifies real effort per account, and your inbox outreach is drowning in everyone else's. At 20 letters, personalization is not a feature. It is the whole play. ## The trigger You do not wait for a signal. You pick. Once a month, sit down and choose the 20 accounts you most want as customers this quarter. Good reasons to pick one: - They match your best current customer almost exactly. - You have a genuine opinion about their business. - A logo on this list would unlock five more like it. If you cannot say why an account is on the list, it is not on the list. ## The audience One person per account: the buyer, not the influencer. At a 30-person company that is usually the CEO or the functional head. Pull the accounts from your CRM or a CSV, and let Sincerely resolve and verify the mailing address before anything prints. Wrong-address letters at this volume are pure waste, so verification is not optional. Twenty is the number for a reason. It is small enough that you can research every account yourself and follow up on every letter personally. If you cannot follow up on it, do not mail it. ## The piece A letter, not a postcard. A letter in an envelope reads as correspondence from a person. A postcard reads as marketing, and this play dies the moment it reads as marketing. The copy has three moves: proof you did the work, one specific observation, one small ask. No pitch deck in prose. Sincerely drafts each letter from your CRM context and researched account facts, and you approve every one before it prints, so the words stay yours. See [the copywriting guide](https://trysincerely.com/guides/direct-mail-copywriting) for the full pattern. Example, founder to founder: > Maya, I read your postmortem on the failed EU launch. The part about support tickets doubling before revenue moved matched exactly what we saw at my last company. I started Acme because of that problem. If you have 20 minutes in the next two weeks, I will show you how three teams your size handle it now. Either way, the postmortem was the best thing I read this month. Sam Five sentences. One observation, one ask, no feature list. ## The follow-up You follow up, not a sequence. Letters land three to five business days after mailing. On day six, send a short personal email: "I mailed you a letter last week about your EU postmortem. Curious if it landed." Reference the letter's content, not the letter itself. If no reply, one LinkedIn touch a week later, then stop. The letter earned you two follow-ups, not ten. ## How to measure it Honestly: 20 letters a month is too small for statistics. A holdout test needs hundreds of accounts per arm to detect a realistic lift. Run the numbers yourself with the [holdout-size calculator](https://trysincerely.com/tools) and you will see why. So do not pretend. Track three plain counts instead: - Replies to the follow-up email, within 30 days of mailing. - Meetings booked with mailed accounts. - Cost per meeting: at [Pilot pricing](https://trysincerely.com/pricing), $199 one-time for 100 pieces, five months of this play costs about $2 per letter. If 60 letters over three months produce zero meetings, change the list or the ask. If they produce three, you have a play worth scaling, and at that point [holdout testing](https://trysincerely.com/holdout-testing) becomes possible and worth doing. Start on the Pilot plan: $199 once, 100 pieces, everything included. That is five months of this play for less than one month of most sales tools. Twenty letters you mean beat two thousand you don't. --- Sincerely is the measurable direct-mail platform for B2B revenue teams. One workflow. One invoice. One report.
