Source: https://trysincerely.com/playbooks/abm-programs Mail earns its place in [ABM](https://trysincerely.com/glossary/abm) the same way ads and SDR touches do: it moves target accounts toward a meeting. The difference is cost and weight. A letter costs $1.25 to $2.00 and lands on a desk. That math works in your 1:1 and 1:few tiers, where each account is worth thousands. In 1:many, use mail only for accounts that show intent. This playbook covers where mail slots in, how to sequence it with the rest of the program, and how to prove it worked. ## The trigger Tier assignment is the trigger. When an account enters a 1:1 or 1:few tier, mail goes into its plan from day one. For the 1:many tier, wait for a signal: a surge in ad engagement, a pricing page visit, or an SDR reply that went cold. Do not mail the whole 1:many list on a schedule. That is demand gen with worse economics, and the demand gen playbook covers it. ## The audience Match depth to tier: - **1:1**: the full buying committee, usually 3 to 8 people per account. Every piece references that account's specifics. - **1:few**: 2 to 4 contacts per account, typically the economic buyer and the champion. Pieces reference the shared pain of the cluster, personalized per person. - **1:many**: one contact per account, the likeliest champion, and only at accounts showing intent. Sync the list from [Salesforce or HubSpot](https://trysincerely.com/integrations) so tier and account owner ride along. Addresses get verified before anything prints, so a stale CRM does not burn budget. ## The piece Letters for 1:1 and 1:few. A letter in an envelope gets opened alone at a desk, which fits a considered, account-specific argument. Use 6x9 postcards for 1:many intent plays, where you want the message read in two seconds without an open. The copy should prove you did the work. Name the account's situation, connect it to one outcome, and make one small ask. For a 1:1 letter to a VP of Engineering at a company that just posted twelve SRE roles: > You are hiring twelve SREs while running four monitoring tools. Most teams in that spot consolidate before the new hires start, not after. I wrote up how two teams your size did it. Fifteen minutes and I will walk you through both. Each Sincerely piece is drafted from CRM context and researched account facts, and a human approves it before it prints. ## The follow-up Mail is one instrument, not a solo. Sequence around the in-home date: 1. Ads on for the account two weeks before the piece lands, so the name is familiar. 2. The piece lands. 3. The SDR calls or emails within three business days, referencing the piece directly: "I sent you a letter about the SRE hiring wave." 4. The account owner sends a LinkedIn connect the same week. The reference in step 3 is the point. It turns a cold call into a warm one. Log the send in the CRM so the SDR knows the in-home window. ## How to measure it Hold out accounts, not contacts. Mail hits a buying committee, so the account is the unit that either progresses or does not. Randomly hold out 10 to 20 percent of each tier and compare meetings and pipeline against the mailed group. The [holdout guide](https://trysincerely.com/holdout-testing) walks through the design. Be honest about sample size. A 1:1 tier of 30 accounts cannot produce a statistically significant readout, and no tool changes that. Read those tiers as case-by-case evidence: meetings booked, deals moved. Reserve real lift math for the 1:few and 1:many tiers, where you have hundreds of accounts. The calculators at [/tools](https://trysincerely.com/tools) tell you what your sample can and cannot detect before you launch. Sincerely locks the design at launch and says plainly when a result is not ready. Mail belongs in the tiers where accounts are worth the postage, and the holdout tells you if you were right. --- Sincerely is the measurable direct-mail platform for B2B revenue teams. One workflow.
