What is Smile.io?

Smile is growing by wiring itself into everyone else's app — including Shopify's AI assistant.

Almost everything on this feed is joint content with another Shopify app: Redo on abandoned carts, Stay AI on subscription churn, Loop on returns, Digioh on zero-party data, Judge.me on reviews. Each follows the same structure — take a moment in the customer lifecycle that another vendor owns, and attach loyalty enrolment or point earning to it. The exception is a genuine product launch, a Sidekick app extension that lets merchants ask Shopify's AI assistant about loyalty program performance.

What is Sendcloud?

Sendcloud is making shipping prices explain themselves before the label is bought.

Sendcloud's November entries target the chores around a label. Customs PDFs upload through API v3, Shipping Rules fill Importer of Record details, and carrier contract rates load from a dragged-in PDF. The latest work is on price accuracy: saved boxes fill dimensions on the Shipping Prices page, missing prices now show the reason, and a warning flags prices that may be incomplete without dimensions.

Smile.io vs Sendcloud: editorial side-by-side

E-COMM
5.0

Smile is growing by wiring itself into everyone else's app — including Shopify's AI assistant.

◆ Current state

Almost everything on this feed is joint content with another Shopify app: Redo on abandoned carts, Stay AI on subscription churn, Loop on returns, Digioh on zero-party data, Judge.me on reviews. Each follows the same structure — take a moment in the customer lifecycle that another vendor owns, and attach loyalty enrolment or point earning to it. The exception is a genuine product launch, a Sidekick app extension that lets merchants ask Shopify's AI assistant about loyalty program performance.

◆ Where it's heading

Smile has stopped positioning loyalty as a destination app and started treating it as a layer that attaches to other moments — a return, a cancellation, a review, an abandoned cart. That is a distribution strategy as much as a product one: each integration borrows another vendor's install base and their moment of customer intent. The Sidekick extension extends the same logic to the platform layer, putting loyalty data where merchants are already asking questions rather than making them open Smile.

◆ Prediction

Expect more co-marketed integrations with adjacent Shopify apps on the same lifecycle-moment template, and further work exposing loyalty data through Shopify's own surfaces. Omnichannel recognition across retail and DTC is the thread most likely to become a product push.

5.0

Sendcloud is making shipping prices explain themselves before the label is bought.

◆ Current state

Sendcloud's November entries target the chores around a label. Customs PDFs upload through API v3, Shipping Rules fill Importer of Record details, and carrier contract rates load from a dragged-in PDF. The latest work is on price accuracy: saved boxes fill dimensions on the Shipping Prices page, missing prices now show the reason, and a warning flags prices that may be incomplete without dimensions.

◆ Where it's heading

Three releases in a week target the same gap: prices that change after the label because dimensions were missing. Sendcloud is moving surcharge and error explanations to the point of quote, which cuts support tickets and post-shipment corrections rather than adding new carriers.

◆ Prediction

Expect dimensions to become harder to skip, likely saved-box defaults in the New Shipment Form or Shipping Rules that apply a box automatically.
