Every iMessage is a chance to
turn a buyer into a regular

Signals turns customer questions and post-delivery check-ins into one iMessage thread that recommends, reassures, and keeps customers coming back.

Hi, does the chore jacket run true to size? I am between medium and large.
Hi Leo, this is Olivia from Apparel Brand. It runs a little roomy through the chest. What is your usual jacket size and how do you want it to fit?
Usually medium. I want to layer a hoodie under it.
I would go large for layering. The washed canvas version is in stock in large, and it pairs well with the navy fatigue pant you viewed.

Great. Is return shipping free if it still feels big?
Yes, exchanges are free within 30 days. I can also send the product link with large selected so you do not have to hunt for it again.
Please send it
Here you go: [large chore jacket]. I will keep this thread open if anything comes up after it arrives.

From first question to repeat order

Signals keeps one iMessage conversation between shopper and brand open across the moments that decide sales, support, and repeat revenue.

Inbound · before they buy Outbound · after delivery

Before Order

A shopper texts a real question about sizing, fit, or shipping, and gets an answer that helps them buy with confidence.

Order

Signals points them to the right product, then handles the live order: changes, cancellations, and where's-my-package.

Delivery

The box lands and Signals checks in, catching fit and quality issues before they turn into a return.

Next purchase

Happy customers volunteer what they want next, and Signals recommends it from their own purchase history.

The post-purchase moments most brands leave on the table

Signals keeps the before-purchase and after-delivery moments connected, so sales, support, returns, and retention do not become separate workflows.

The 1:1 conversation your stack never starts

Klaviyo, Attentive, Postscript, and Omnisend broadcast. Gorgias and Zendesk react. Loop and Narvar process returns. Signals starts the 1:1 iMessage conversation those systems are not built to start.

Manage every buyer question in one operating surface

Most inbound and post-delivery conversations resolve fully with AI. When something unusual appears, it escalates to a human in the same thread, and your team can step in without losing context.

Ideas for the post-purchase channel

Questions, answered

Learn how Signals turns one-time buyers into repeat customers and drives measurable retention revenue.

How often do customers text Signals?

We see about 2.5 texts per 1,000 impressions, with roughly a 40/60 support-to-sales mix. About 20% of sales conversations result directly in a sale.

How does Signals drive repeat purchases?

Signals creates additional revenue for DTC brands in two ways: it helps new customers buy by answering the questions that block checkout, then it increases LTV from existing customers through reorders, cross-sells, upsells, and subscription saves. Brands see 50%+ more repeat purchases from engaged customers.

What kind of revenue impact should we expect?

Results vary by brand, but the A/B tests give concrete numbers. Jordan Craig made an extra $30 in repeat revenue from every Signals conversation after 2 weeks, and Quaker Marine saw 51% more repeat purchases among engaged customers. Beyond that lift, brands get more new-customer purchases from answered questions plus cross-sell, upsell, and subscription revenue. We scope a refundable 4-week pilot that runs as an A/B test against a holdout, so you can measure it on your own numbers.

Who is Signals built for?

DTC brands and e-commerce companies that want to turn one-time buyers into repeat customers. Best for brands selling physical products with natural reorder or cross-sell opportunities. Not a fit for teams looking for a bulk SMS marketing tool.

How is this different from email or SMS marketing?

Marketing campaigns broadcast offers to a list. Signals starts 1:1 conversations with customers at the moment they are most engaged, right after they receive their order. Customers reply, share feedback, and buy again inside that conversation. That is why engagement rates reach 61%, versus single-digit rates for email and traditional SMS. Read more in SMS CX Shouldn't Be NoReply.

Why iMessage instead of email or app notifications?

iMessage is where customers already have real conversations. Messages are read in minutes, not hours. Customers can reply instantly, share photos, and pick up the thread later. No app to install, no inbox to compete with. The result is 61% engagement and real two-way conversations that drive revenue.

Does proactive outreach feel spammy to customers?

The opposite. A well-timed check-in after delivery feels like genuine care, not marketing. Customers respond because the outreach is personal and helpful. About 15% of customers voluntarily share future buying intents during the conversation without being asked.

How does Signals handle subscription retention?

Signals detects early churn signals like product buildup, skipped orders, or dissatisfaction during post-purchase conversations. Instead of waiting for a cancellation, it proactively adjusts delivery frequency, offers alternatives, or resolves issues, saving subscriptions before they are lost.

How long does it take to see results?

Setup can take 10-20 minutes total when access is ready, because Signals lives on top of your customer stack instead of replacing it. The refundable pilot then runs as a 4-week A/B test to tune the first playbooks and measure lift against a holdout. The goal is to prove roughly 10x ROI by the end of the pilot. Book a demo to scope yours.

What integrations do you support?

Signals connects to Shopify, Gorgias, Zendesk, Gladly, Loop, Redo, Subscribfy, Listrak, Manhattan Associates, EasyPost, Slack, and more. It lives on top of the customer stack you already use, so your helpdesk, return portal, SMS marketing tool, and commerce systems can stay in place. You provide access to your commerce platform and an escalation path for support; we handle the rest.

Can we connect our own AI tools to Signals over MCP?

Yes. Signals runs a remote MCP (Model Context Protocol) server, so you can connect Claude, Codex, and other MCP clients straight to your Signals workspace. An org admin creates scoped, revocable access tokens, or connects over OAuth, to expose read-only analytics, catalog, orders, customers, and conversation data, plus admin settings when you opt in. Your team can pull performance numbers and manage Signals from the tools they already use, and a brand can let its own AI agent reply to customers through the same connector. See our compliance page for how MCP-initiated messages are governed.

How do you measure ROI?

Every pilot is refundable and includes an A/B test with a holdout group. We measure incremental new-customer conversion, revenue per customer, cross-sell conversion, repeat purchase rate, and subscription retention. Signals typically charges per engaged conversation per month, so ROI is measured against actual conversation volume and cost.

How is pricing structured?

Signals typically charges per engaged conversation per month. Exact pricing depends on expected volume and refundable pilot scope, which is why we usually scope pricing and ROI together in the demo.

How do you handle security and compliance?

We separate support and customer-initiated conversations from optional unsolicited marketing. When marketing is enabled, we gate brand-initiated sends by channel, consent state, and restricted-state signals, honor STOP-style and natural-language opt-outs, and maintain an active SOC 2 program. See our compliance page and security page.
