PostPilot

PostPilot is a direct-mail platform for ecommerce brands, connecting postcard and catalog campaigns with customer and site data. It is strongest for merchants coordinating acquisition and retention across several campaign types; occasional senders may find its paid tiers more than they need.

Overview

PostPilot supports prospecting, retargeting, abandoned-cart, loyalty, subscription, winback, and retail campaigns. That range makes it a fit for brands building mail into an ongoing customer program, rather than a one-off mailing workflow. There is no sending minimum, so a brand can mail a single card, though card and postage costs apply even on the free plan.

Key features

Audience building and personalization

MailMatch connects email addresses to physical mailing addresses using PostPilot’s proprietary algorithm and dataset. AcquisitionAI finds prospects through lookalike audiences, while SiteMatch retargets anonymous site browsers. Together, these tools make PostPilot particularly relevant to ecommerce marketers seeking to extend digital audiences into physical mail. AcquisitionAI prospecting data costs $0.07 per recipient, a variable charge to account for when targeting large audiences. The platform supports one-to-one personalization and address verification.

Measurement and connections

Real-time dashboards, holdout-tested iROAS measurement, and cross-channel attribution give marketing teams ways to evaluate mail’s contribution. Shopify customer recipients are automatically tracked for 60 days. PostPilot connects with services including Shopify, Klaviyo, Yotpo, Attentive, Omnisend, Recharge, Loyalty Lion, and Loop Subscriptions, and offers an open API for connecting other systems. The company says aggregated, anonymized transactional data trains its AI products; customers cannot access or specifically benefit from another customer’s data.

Mail formats include 4x6, 6x9, and 6x11 postcards, handwritten cards, Cardalogs, and A5 pieces. The breadth is useful for teams varying their mail creative, while the API and ecommerce integrations are more compelling for data-led campaigns than for simple print-and-send needs.

Pricing

PostPilot is freemium, but free means access to the platform rather than free mail. Every plan requires payment for postcards and postage, and the paid tiers add a subscription charge.

Growth and Pro are priced for different sales and mailing scales, so the cheaper annual Growth rate is not necessarily the better fit for a high-volume sender. The published paid-from price is $82.50 a month on annual billing. No trial is needed to start with the free plan, and the pricing FAQ says there is no minimum order.

Platforms

PostPilot is available on web and through an API. The API is useful for teams connecting campaign data from systems beyond the named integrations; teams seeking only a basic web mail tool may not need that flexibility.

Who it's for

PostPilot suits ecommerce brands that want to coordinate customer acquisition, re-engagement, and retention through direct mail, particularly those already using ecommerce and marketing platforms such as Shopify or Klaviyo. Growth is aimed at brands with $1m–$3m in annual sales, while Pro and Enterprise address larger mailing volumes. A small business testing a few pieces can start free, but should budget for the cards and postage.

Pros and cons

• Pros: One platform covers prospecting through winback and retail campaigns, rather than only sending mail.
• Pros: Dashboards, holdout-tested iROAS, cross-channel attribution, and 60-day Shopify recipient tracking support campaign evaluation.
• Pros: No minimum send and a full-featured free platform lower the barrier to trying direct mail.
• Cons: Free does not include cards or postage, and Growth and Pro add monthly costs.
• Cons: AcquisitionAI prospecting data costs $0.07 per recipient, adding expense as audiences scale.
• Cons: The defined Growth and Pro sales or volume targets may not suit organizations outside those ranges; Enterprise requires custom pricing.

Alternatives

Direct Mail Automation Software is the broader category to browse when comparing more options. Choose DocuPost instead if a free web/API plan with one user, letters and postcards, no send limits, and pay-per-mailpiece pricing better fits your workflow. Inkit is another freemium web/API option, with a free tier that includes three signature requests monthly, one seat, and 10GB of storage.

Consider Lob Address Verification if the priority is address verification, or Postalytics if unlimited campaigns, templates, and lists on a one-user free plan are more important. Sincerely offers a free audit plan that cannot mail, while Stannp has a free tier with one user, one template, 50,000 contacts, and 20 virtual printer items monthly. thanks.io offers pay-as-you-go with no monthly subscription fee, and ZAP~POST is another option to compare.

Verdict

PostPilot is a strong choice for ecommerce brands that want direct mail tied to customer data, multiple campaign goals, and measurable performance across channels. Its range of audience tools and campaign reporting is the main reason to choose it; the reasons to look elsewhere are equally clear for smaller or price-sensitive senders: mailed pieces cost extra even on Free, AI prospecting carries a recipient fee, and paid plans become costly as monthly volume rises.
