Source: https://trysincerely.com/guides/direct-mail-in-outbound-sequences Put the mail piece in the middle of the sequence, not the start. Trigger it after two or three digital touches get no reply. Then time the follow-up call off delivery, not the send date. USPS publishes a 1 to 5 day service standard for First-Class mail, and printing adds days before that, so a call scheduled "2 days after send" lands before the piece does. The mail is not the close. It is the pattern break that makes the next call warm. ## Which step gets the mail Three positions work. Pick one and test it. - **Step 3 or 4, after silence.** Two emails and a call go unanswered, then mail goes out. This is the default. You spend $1.50 to $2.00 only on prospects who ignored the free touches. - **Step 1, for a small named list.** For 20 to 50 high-value accounts, open with mail. A letter to a VP beats a cold email to a VP. Expensive per touch, so reserve it for accounts worth a real pursuit. - **The revival step.** The last touch before you close the sequence. "Sequence finished, no reply" is itself a trigger. See the [closed-lost revival playbook](https://trysincerely.com/playbooks/closed-lost-revival) for the same logic applied later in the lifecycle. Do not mail every prospect at every step. Mail is the scarce touch. Scarcity is why it works. ## What triggers the send Tie the send to a behavior, not a date. - **No reply after N touches.** The workhorse. Prospect finished steps 1 through 3 with no response. - **Engagement without reply.** Opened three emails, clicked once, never answered. This person is aware of you. Mail converts awareness into a conversation. - **A signal.** Funding round, new executive, hiring spike. A new executive is the strongest version: they have a mandate and no incumbent loyalty. In practice the trigger is a list operation. Your sequencer tags prospects who hit the condition. You sync that segment to Sincerely through [Salesforce, HubSpot, or a CSV export](https://trysincerely.com/integrations), and a [campaign](https://trysincerely.com/campaigns) picks it up. Sincerely has no native Outreach or Salesloft integration today, so the CRM or a CSV is the bridge. Sincerely then writes each piece for the individual recipient from CRM context, and a human approves before anything prints. ## Time everything off delivery, not send This is the step most teams get wrong. The send date is when printing starts. Delivery is when the prospect holds the piece. Plan on roughly 3 to 7 business days between them: [USPS publishes 1 to 5 days](https://www.usps.com/ship/mail-shipping-services.htm) for First-Class delivery, and production runs before the piece ever enters the mail stream. Marketing Mail takes longer. Every downstream touch should key off delivery: - **Day of delivery, or day after: the rep calls.** "I sent you something, did it land?" is a real opener. It only works if the piece has actually arrived. - **1 to 2 days after delivery: a short email.** Reference the piece by name. One line, one ask. - **Never before delivery: nothing.** A call that mentions mail the prospect has not received burns the surprise. Sincerely mails through Lob, and per-piece delivery events flow back so the rep task fires on confirmation, not on a guess. If your stack cannot see delivery events, assume 5 business days and accept the slop. It is worse, but it is better than calling on day 2. ## Coordinating the rep The rep needs three things before the call: 1. **What the piece said.** The rep must be able to quote it. Sincerely pieces are individually written, so put the final copy in the CRM activity. 2. **A task that fires on delivery.** Not a calendar guess. The task is "call within 24 hours of delivery confirmation". 3. **A talk track that uses the piece.** The piece earns 15 seconds of attention on the phone. The rep spends those seconds on the prospect's problem, not on the mail itself. ## An example sequence A 14-business-day sequence for a mid-market target, mail at step 4: | Day | Step | Touch | | ----------------------- | ---- | --------------------------------------------------- | | 1 | 1 | Email 1: problem-led, one ask | | 3 | 2 | Call 1 plus LinkedIn connect | | 6 | 3 | Email 2: new angle, short | | 7 | 4 | Mail triggers: 6x9 postcard or letter, personalized | | Delivery (day 11 to 14) | 5 | Rep calls within 24 hours of delivery confirmation | | Delivery + 2 | 6 | Email 3: references the piece, one line | | Delivery + 5 | 7 | Call 2, then break up email | Cost of the mail step: $1.40 to $2.00 per piece on most Sincerely plans, print and postage included. That is one touch that costs more than the other six combined, aimed only at prospects who earned it by going quiet. ## Measure it or skip it Hold out a slice of the eligible segment and run the sequence without the mail step. Compare reply and meeting rates between the two groups. Sequenced touches make last-touch attribution useless, so lift against a [holdout](https://trysincerely.com/holdout-testing) is the only honest readout. Sincerely locks a holdout into the campaign design at launch and reports lift with confidence intervals, including when the result is not ready to call. The mail piece does not book the meeting. It makes the prospect pick up the call that does. --- Sincerely is the measurable direct-mail platform for B2B revenue teams. One workflow. One invoice. One report.
