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.
Canvas chore jacket
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.
Hi Claire, this is Olivia from Furniture Brand. Your new dining chairs arrived! How are they looking in the space?
They look good, but I spilled some wine on them
Oh no, but don't worry—our chairs are designed for easy living! You can easily wipe the rattan frame with a damp cloth and mild soap, and the cushion covers are removable and machine washable on a gentle cycle.
I'm thinking of a rug that matches them
The striped rug in navy is a classic foundation that pairs beautifully with your white dining chairs. It is designed for indoor-outdoor use, making it easy to clean under a dining table.
Striped navy rug
What are the sizes?
The rug is available in 2x3' ($98), 3x5' ($448), 6x9' ($898), 8x10' ($1,798), and 9x12' ($2,498). Do you have a specific dimension in mind?
Ok I guess I want the 8x10
The 8x10 striped rug in navy is a beautiful choice to anchor your dining space. May I go ahead and use the shipping and billing information from your recent chair order to place this for you?
Confirm what address you have for me and what cc
I have your shipping address as 1240 Ocean View Terrace, Half Moon Bay, CA 94019, and the card on file ending in 7812. Shall I go ahead and place the order for the 8x10 rug?
Yes please
I have placed the order for your 8x10 rug in navy, and your confirmation number is [confirmation number].
Hi Robin, this is Olivia from Dogfood Brand. How is your pup enjoying the new food so far?
Not sure he is a picky eater
I'm sorry to hear he's being a little picky with the new food! Have you tried our recommended gradual 7-10 day transition by mixing it with his old meals?
No I haven't yet
no worries, a gradual transition usually helps picky eaters adjust! try mixing 25% of the new food with 75% of his current meals for the first 3 days, then slowly increase the amount over 7-10 days.
Ok will try
perfect, let me know how the transition goes! we're always here if you need any more tips.
Btw do you sell toppers or snacks
we don't carry snacks right now, but we do offer a topper plan! it includes half-portions of our meals designed specifically to mix with your dog's current food.
Ooh, what flavors are available?
you can choose from our unkibble recipes or our fresh meals. let me know if any of those sound good for him!
Lamb fresh
great choice. you can easily switch your subscription to a topper plan with that recipe by visiting your account: [link to account].

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

Question

Shoppers text Signals product questions that help them make a buying decision.

Order

New orders can be made through Signals threads, and existing orders get support.

Delivery

Signals checks in with customers after delivery to make sure they have an excellent experience.

Next purchase

We continue building relationships with customers, cross-selling, and driving repeat revenue.

Frequently Asked Questions

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 typical outcomes include more new-customer purchases from answered questions, 50%+ repeat purchase lift among engaged customers, 4-6x higher conversion than other text campaigns, and measurable cross-sell and upsell revenue. We aim to prove 10x ROI through a refundable 4-week pilot that runs as a randomized control trial. See how Quaker Marine drove 51% more repeat purchases.

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 randomized control trial 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 integrates with Shopify, Gorgias, Listrak, Slack, and 50+ other platforms. 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.

How do you measure ROI?

Every pilot is refundable and includes a randomized control 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 support mutual NDA and DPA, follow SMS opt-out best practices, and maintain an active SOC 2 program. See our security page.
