PostPilot

PostPilot is a direct-mail platform for ecommerce brands, with tools for matching customer emails to mailing addresses, finding prospects, and measuring campaigns. It is best suited to merchants using direct mail alongside digital retention and acquisition; smaller senders can start without a platform fee, while postage and cards still cost extra.

Overview

PostPilot covers the lifecycle of an ecommerce customer, from prospecting and abandoned-cart follow-up to loyalty, subscription, winback, and retail campaigns. Its strongest case is for brands that want direct mail tied to customer and site data rather than a standalone mail-sending service. The trade-off is that the platform subscription is only part of the cost: every mailed piece carries a separate production and postage charge.

Key features

Address matching and prospecting

MailMatch uses a proprietary algorithm and dataset to connect email addresses with physical mailing addresses, helping brands turn customer records into mailing audiences. AcquisitionAI is a lookalike engine for prospect discovery, while SiteMatch targets anonymous site browsers. AcquisitionAI prospecting data costs $0.07 per recipient, so prospecting can add a meaningful variable cost at scale.

Campaign measurement

Real-time dashboards, holdout-tested iROAS measurement, and cross-channel attribution give marketers ways to assess whether mail is contributing to results. For Shopify customers receiving a postcard or handwritten card, PostPilot automatically tracks activity for 60 days. That fixed window is useful for near-term attribution, but it is not a promise of ongoing tracking beyond that period.

Connections and formats

Integrations include Shopify, Klaviyo, Yotpo, Attentive, Omnisend, Recharge, Loyalty Lion, and Loop Subscriptions; an open API can connect other systems. Supported formats include 4x6, 6x9, and 6x11 postcards, handwritten cards, Cardalogs, and A5 formats. One-to-one personalization and address verification support targeted campaigns, while the no-minimum sending policy lets teams send one card or as many as one million.

PostPilot says aggregated, anonymized transactional data is used to train its AI products, and that customers cannot access or specifically benefit from another customer's data. Support contact: [email protected].

Pricing

The Free plan costs $0.00 per free and includes the full platform and 10+ analytics reports. There is no platform charge, but postcards and postage are paid per send. It is a practical starting point for testing campaigns without a subscription commitment, though not a free mailing service.

Growth is $82.50/mo with annual billing or $99/mo with monthly billing. Cards start at 68¢ including postage, and the plan is built for brands doing $1m–$3m/yr in sales. It suits growing ecommerce teams that want the platform's campaign tools and can justify a recurring fee; the annual price requires a billing commitment, while month-to-month costs more.

Pro is $419/mo with annual billing or $499/mo with monthly billing. Mailpieces cost 64¢ or less including postage, based on volume, and the plan is built for up to 50,000 mailpieces/month. It is aimed at higher-volume programs where lower per-piece pricing can offset the larger subscription. Enterprise has custom pricing for brands sending 50,000+ mailpieces/month, with custom volume pricing.

Platforms

PostPilot is available on the web and through an API. The API is useful for brands connecting campaign data from systems beyond the listed integrations, while the web platform serves teams managing campaigns directly.

Who it's for

PostPilot is a strong fit for ecommerce marketers who already have customer data in platforms such as Shopify or Klaviyo and want to coordinate direct mail with prospecting, retention, and attribution. Its free platform tier lowers the barrier to starting, and the absence of a sending minimum accommodates small tests. Brands sending at substantial volume can consider Pro or custom-priced Enterprise. It is a weaker fit for anyone seeking mail without per-piece costs or a simple address-verification tool rather than a full campaign platform.

Pros and cons

• Pros: Free access includes the full platform and 10+ analytics reports, so teams can explore campaign capabilities before paying a subscription.
• Pros: MailMatch, prospecting, retargeting, and multiple campaign types bring acquisition and retention workflows into one direct-mail platform.
• Pros: No sending minimum makes small pilots possible, while volume-based Pro pricing is designed for larger mailing programs.
• Cons: Free does not mean free mailing: postcard and postage costs apply, and AcquisitionAI prospecting adds $0.07 per recipient.
• Cons: The lowest paid price depends on annual billing; Growth costs $99/mo when billed monthly.
• Cons: Shopify postcard tracking is limited to a 60-day window, which may not suit evaluation of longer customer journeys.

Choose ZAP~POST if a free annual plan with up to 60,000 Zaps, unlimited campaigns, and two integrations better matches a workflow built around Zaps. DocuPost is worth considering for its free plan with one user, letters and postcards, and no send limits, with mail charged per piece. Choose Inkit if signature requests and document storage are the priority. Postalytics offers a free plan with unlimited campaigns, templates, and lists, making it an option for campaign management with per-piece mail charges. Sincerely has a free audit plan that cannot mail, suited to teams focused on auditing and preparing mail before sending. Stannp may suit teams that want a free plan with one user, one template, and 50,000 contacts. thanks.io offers pay-as-you-go pricing with no monthly subscription fee and full API access.

Verdict

Choose PostPilot if your ecommerce brand wants direct mail connected to customer data, prospecting, and campaign measurement, especially when its Shopify and marketing integrations fit your stack. Its no-fee platform tier and no minimum make it approachable, but card, postage, and prospecting charges mean the real cost rises with use. Look elsewhere if you need a narrowly focused mail utility or want to avoid recurring platform and per-piece costs as your campaigns grow.
