Source: https://trysincerely.com/playbooks/demand-gen Run direct mail the way you run a paid channel: fixed budget, locked experiment, holdout, readout. The play is simple. Carve 5 to 10 percent of your paid budget into mail, point it at accounts your ads already touch, and measure lift against a holdout. Mail earns more budget only when the readout says it moved pipeline. Run it when your paid channels have plateaued on the same target accounts and the next dollar of ad spend buys impressions, not meetings. ## The trigger The trigger is saturation, not a calendar. You know it when CPMs on your target account list keep rising and reply rates keep falling. If the same 500 accounts have seen your LinkedIn ads for two quarters and your cost per opportunity is climbing, that is the signal. Mail reaches the inbox that has no ad blocker: the desk. ## The audience Pull the accounts already in your paid audiences. Sync them from [Salesforce or HubSpot](https://trysincerely.com/integrations), or upload a CSV. Two rules: - Only accounts with a verified business address. Sincerely resolves and USPS-verifies addresses before anything prints, and remote-first accounts with no mailable address drop out. Expect to lose 20 to 40 percent of a raw list here. That is the channel working, not failing. - Hold out 20 to 30 percent of the list at random, at the account level. Small programs need big holdouts to detect anything. Size it with the [holdout calculator](https://trysincerely.com/tools) before launch, not after. ## The piece Start with a 6x9 postcard. It is cheap enough to test in volume, and nothing to open means nothing to throw away unread. On a Growth plan it runs $1,500/month with 1,300 pieces included, so a 400-piece monthly test fits with room to spare. The copy should say one researched thing about the account and make one ask. Not a brochure. Example: > Maya, your team posted three RevOps roles last month. Scaling headcount usually means scaling the reporting mess first. We help teams like Datadog's cut pipeline reporting from days to hours. Worth 20 minutes? Scan the code or reply to my email. Sincerely writes each piece for one recipient from CRM context and account research, and you approve every piece before it prints. See [the campaigns page](https://trysincerely.com/campaigns) for how a batch moves from draft to mailbox. ## The follow-up Mail lands over a 3 to 5 day window. Time the follow-up to the landing window, not the send date: 1. Day of expected delivery: SDR email that references the card. "Did the postcard make it to your desk?" outperforms a cold opener. 2. Two days later: call. The card gives the rep a reason to dial that is not "just checking in." 3. Day 7: LinkedIn touch, then back into the normal sequence. The card is a door opener for the sequence, not a standalone channel. Skipping follow-up is the most common way this play dies. ## How to measure it Report lift, not responses. Compare pipeline created in mailed accounts against the holdout over a fixed window, usually 60 or 90 days. Sincerely locks the experiment design at launch and reports lift with confidence intervals, and it says plainly when a result is not statistically ready. Be honest about sample size. A 400-piece monthly test cannot detect a 5 percent lift. It can detect a 30 to 50 percent lift on a decent baseline, and B2B mail to warm named accounts often clears that bar. Check what your sample can actually see with the [lift-significance calculator](https://trysincerely.com/tools) before you promise the CFO a number. For the CFO, report two things each quarter: incremental pipeline per dollar versus your paid channels, and the confidence interval around it. QR scans and CRM matchback are supporting evidence, not the headline. The full method is in [the holdout testing guide](https://trysincerely.com/holdout-testing). Budget like paid, test like paid, report like paid, and mail stops being a stunt and starts being a channel. --- Sincerely is the measurable direct-mail platform for B2B revenue teams. One workflow.
