Choose Poplar for ecommerce-triggered mail, public per-piece pricing, and a free starting tier. Source: https://trysincerely.com/compare/postie-vs-poplar Postie is better for broad consumer acquisition built on lookalike audiences. Poplar is better when ecommerce events should trigger affordable mail with published pricing. Both target household mailboxes, but they enter the program at different points. Postie starts with an audience problem and applies lookalikes, machine-learning segments, and site-visitor identity resolution. Poplar starts closer to the campaign trigger, with Shopify, Klaviyo, Customer.io, site visitors, and order matchback in the mix. ## The two platforms at a glance | Dimension | Postie | Poplar | | -------------- | --------------------------------------------------------- | ------------------------------------------------------------------- | | Core product | Consumer acquisition and retargeting at scale | Trigger-based household mail at volume | | Audience tools | Lookalikes, ML segments, site-visitor identity resolution | Site visitors, lookalikes, ecommerce and customer-data integrations | | Formats | Its site does not publish a format list | Postcards, letters, bifolds, trifolds | | Measurement | ROAS, CPA, and CVR dashboards | Delivery tracking, order matchback, randomized holdouts | | Typical volume | Tens of thousands of pieces and up | Consumer-volume campaigns | | Pricing | Not published; custom quote | Free, Lite, Pro, and custom Enterprise tiers | ## Audience modeling: Postie is better Postie is the stronger pick when the job begins with finding more households like your current customers. It builds lookalike audiences from a customer file, creates machine-learning segments, and matches anonymous site visitors to home addresses. That is a serious acquisition toolkit, not merely a way to upload a mailing list. Poplar also offers lookalike modeling and website visitor retargeting. Its public positioning, though, puts more weight on event-driven mail connected to ecommerce and customer-data systems. Choose Postie when modeled prospecting is the center of the brief rather than one campaign option. ## Ecommerce triggers and formats: Poplar is better Poplar fits the marketer who wants a postcard to follow an abandoned cart or a winback event. Its connections to Shopify, Klaviyo, and Customer.io put direct mail beside existing lifecycle messages. Postie's site does not publish those named integrations. Poplar also publishes a broader physical menu: postcards, letters, bifolds, and trifolds. Postie's site does not publish its available formats, so buyers with a fixed format requirement should confirm it during the sales process. ## Measurement: Poplar explains more Postie reports ROAS, CPA, and CVR for high-volume consumer drops. That language will be familiar to an acquisition team with enough conversions to feed the dashboard. Poplar publishes more detail about causal measurement. It supports randomized holdout groups and incremental lift over a 30, 60, or 90-day window, alongside last-touch order matchback. If the test design must be clear before a sales call, Poplar gives you more to evaluate. ## Pricing reality: only Poplar publishes numbers Postie does not publish pricing. As of August 2026, [postie.com](https://www.postie.com) has no pricing page or self-service tiers and sends buyers to a contact form for a volume-based quote. Poplar publishes a Free tier at $0/month with no minimums, Lite at $249/month or $208 annual, Pro at $499/month or $416 annual, and custom Enterprise pricing, as of August 2026. On [Poplar's pricing page](https://heypoplar.com/pricing), 4x6 postcards run from $0.73 on Free to $0.55 on Pro, color letters from $0.84 to $0.72, and trifolds from $1.01 to $0.89. Email-to-address append and lookalike modeling each add $0.07 per match or address. ## Which is better for what - Modeled consumer acquisition: Postie, because lookalikes and machine-learning segments sit at the center of the product. - Abandoned-cart and winback mail: Poplar, because it names the ecommerce and customer-data connections that drive those triggers. - A campaign that needs bifolds or trifolds: Poplar, which publishes those formats. - A buying process that needs public unit costs: Poplar. Postie requires a quote. - ROAS, CPA, and CVR reporting: Postie names all three for high-volume drops. ## Where Sincerely fits Sincerely runs the B2B mail channel end to end, building audiences from your CRM, writing each standard postcard or letter for one recipient, and measuring lift against account-level holdouts. Handwritten 4x6 postcards and letters are written by hand with a real pen. Sincerely also sends gifts on a recurring plan: 47 physical gifts with a personalized note, US prices starting at $49, and the exact price shown before confirmation, in the United States and Canada. See [gifts](https://trysincerely.com/gifts). Published pricing starts at a $199 one-time pilot for 100 live pieces. It does not provide Postie's consumer acquisition modeling or Poplar's ecommerce-triggered household mail, as the individual reviews of [Postie](https://trysincerely.com/vs/postie) and [Poplar](https://trysincerely.com/vs/poplar) explain. ## The bottom line Choose Postie when finding and acquiring new consumer households is the main job and a custom contract suits the scale. Choose Poplar when lifecycle triggers, published per-piece economics, and an explicit holdout method matter more. Get a Postie quote before deciding, because a feature verdict without comparable pricing is only half a buying decision. ## Related questions - [Sincerely vs Postie](https://trysincerely.com/vs/postie): Postie is built for consumer acquisition at scale.
