PostPilot vs Sincerely

PostPilot is a direct mail platform for ecommerce brands using postcards and catalogs to acquire, retarget, and retain customers. Campaigns cover prospecting, retargeting, abandoned carts, loyalty, subscriptions, winback, and retail. MailMatch links email addresses with physical mailing addresses. AcquisitionAI helps find lookalike prospects, while SiteMatch retargets anonymous site browsers. Reporting includes real-time dashboards, holdout-tested iROAS measurement, and cross-channel attribution. Listed integrations include Shopify, Klaviyo, Yotpo, Attentive, Omnisend, Recharge, Loyalty Lion, and Loop Subscriptions; an open API can connect other systems to campaigns. PostPilot automatically tracks Shopify customers who receive a postcard or handwritten card for 60 days. There is no sending minimum. The free plan has no platform cost, but postcards and postage are paid separately. Growth costs $82.50 a month with annual billing; monthly billing is 99 USD per month. Its AI prospecting data fee is $0.07. Pro costs $419 a month with annual billing, and Enterprise pricing is custom.

Sincerely is web software for B2B direct-mail campaigns using CRM or CSV audiences, personalized printed pieces, and measurement against account-level holdout groups. Salesforce and HubSpot sync account, contact, opportunity-stage, and campaign-membership data, and CSV import is supported. The product drafts personalized writing from account research and links each factual claim to a source. Drafts require human approval before printing, and edits are versioned. Postcards and letters can be mailed; handwritten notes and gifts are not live because their fulfillment adapters are not built. Address verification and correction are included on every plan, with low-confidence addresses routed for review. Every plan includes account-level holdouts, and Sincerely says five of eight campaign types measure lift against a holdout. When a plan reaches its monthly cap, live campaigns pause rather than print additional pieces. The free Audit plan supports imports, a mailability audit, brand designs, and draft editing, but cannot mail. Paid plans start at $250 a month; Pilot is 199.00 USD once.
