Source: https://trysincerely.com/playbooks/sdr-teams This play gives an SDR team direct mail without a mail program. No vendor evaluation, no marketing budget line, no swag closet. Each rep gets a small per-account budget, two tiers of piece, and a rule for when to send. Run it when your team already works a named account list and your calls and emails have flatlined on the top tier. ## The trigger The trigger is rep judgment inside two tiers, not a marketing calendar. - Tier 1, top 20 accounts per rep: send after two weeks of no reply across calls, email, and LinkedIn. Mail is the pattern break, not the opener. - Tier 2, the next 50: send only on a signal. A new VP, a funding round, a champion who went quiet. See the [new executive play](https://trysincerely.com/playbooks/new-executive) for the strongest version of that signal. Budget per account keeps this sane. At [Starter pricing](https://trysincerely.com/pricing), a letter costs $1.75 past the included pieces. Cap Tier 1 at three pieces per account per quarter, about $5.25, and Tier 2 at one. A rep spending $50 a month on mail is running this play at full tilt. ## The audience The person you are already calling, plus their boss. Not the whole buying committee. SDR mail works because it lands on the same desk your voicemails die on. Sync the account list from Salesforce or HubSpot so addresses resolve and verify before anything prints, and so a rep never hand-types a suite number. One rule: if you would not call them, do not mail them. Mail is a touch in the sequence, not a separate campaign. ## The piece Letters for Tier 1, 6x9 postcards for Tier 2. A letter in an envelope gets opened at a desk and reads as one person writing to another, which is the whole point. A postcard is cheaper and faster to scan, which fits a signal-based nudge. The copy says what your best cold email would say if it were guaranteed to be read: one researched fact about the account, one specific problem you solve, one ask. Sincerely drafts each piece from CRM context and account research, and the rep approves it before it prints. Example, Tier 1 letter: > You posted four SDR roles in Austin last month. Teams that grow that fast usually hit the same wall: reps burn hours building lists instead of calling. We fixed that for two companies your size. Worth 15 minutes? I will call Thursday morning. Note the last line. The piece names the call before the call happens. ## The follow-up Mail without follow-up is decoration. Letters land in three to five business days, so put the call task on the rep's calendar for day four and day six. Open with the piece: "I sent you a letter about your Austin hiring, did it land?" Even a no is a conversation. Then run your normal sequence. The [outbound sequence guide](https://trysincerely.com/guides/direct-mail-in-outbound-sequences) covers the timing in detail. Do not gate follow-up on delivery confirmation. Call on schedule either way. ## How to measure it Be honest: an SDR team mails dozens of accounts a quarter, not thousands. That sample cannot prove lift on its own, and pretending otherwise burns trust with whoever funds next quarter. Report two things: 1. Activity you can count. Pieces sent per tier, reply rate on the day-four call versus your baseline connect rate, meetings booked within 30 days of a piece. 2. What you cannot yet claim. Say "12 pieces, 3 meetings, no control group" plainly. If the play earns a real budget, launch it as a campaign with a locked holdout so the readout reports lift with confidence intervals, and says when the result is not ready. The [holdout guide](https://trysincerely.com/holdout-testing) explains the design, and the [free calculators](https://trysincerely.com/tools) tell you how many accounts you need before a lift number means anything. Mail earns its seat the same way an SDR does: one specific message, on time, followed by a call. --- Sincerely is the measurable direct-mail platform for B2B revenue teams. One workflow. One invoice.
