Email & SMS for Shopify brands
We build original Klaviyo email and SMS programs for Shopify and ecommerce brands — no recycled templates, every message A/B tested, and CAN-SPAM/TCPA compliance built in from the first send.
20 minutes. We review your flows, list health, and compliance risk — no obligation.
What we do
We don't do everything. We do retention — the channels you own — and we go deep on them.
01
Core flows built for your brand — welcome, abandoned checkout, post-purchase, winback — plus a campaign calendar planned around your launches and margins. Copy written in your voice, not pulled from a swipe file.
02
Compliant two-way SMS: 10DLC registration handled, quiet hours respected, clear opt-out on every send. We use SMS where it earns its keep — restocks, drops, and time-sensitive offers — not as a second inbox to flood.
03
Popups and signup forms tested for conversion, with consent language that holds up. Every subscriber is someone you're legally allowed to message — and someone actually worth messaging.
Why us
A single TCPA violation can cost $500–$1,500 per text. Carrier filtering can silently kill your SMS deliverability. A spam-folder reputation can take months to repair.
Most agencies treat this as legal fine print to deal with later. We build it into every flow, list, and campaign from day one — because the fastest way to lose the revenue in your list is to abuse it.
Clear, provable consent for every subscriber. No purchased lists, no pre-checked boxes, no gray areas.
Registered sending, quiet hours, frequency caps, and opt-out honored instantly — so texts get delivered and you don't get sued.
Honest subject lines, a working unsubscribe, and your physical address on every single send.
List hygiene, sending warm-up, and engagement segmentation keep you in the inbox instead of the spam folder.
Our process
If you've seen an agency's "proven flows" deployed identically across fifty stores, you know why they stop working. Here's what we do instead.
Step 1
We study your brand, customers, margins, and past sends before we write a word. What you sell shapes what we build.
Step 2
Flows, campaigns, and capture designed around your offer structure and customer journey. Original copy and design — nothing copy-pasted.
Step 3
Subject lines, copy, send times, offers — tested head-to-head with your audience. We keep what the data proves and cut what it doesn't.
Step 4
Monthly reporting on revenue per recipient, click rate, flow conversion, and list health — not vanity open rates. The program compounds instead of going stale.
Every flow, template, segment, and campaign lives in your Klaviyo account, under your ownership, with full access at all times — not just at offboarding. If you leave, it all stays with you.
How we measure success
No case studies to share yet — Market Weld is a new agency. Here's exactly what we track and why, so you know what to expect from month one.
The clearest read on whether a flow or campaign is actually earning its place in the calendar.
Unlike opens, clicks aren't inflated by Apple Mail's proxy pixel — a real signal of whether the message landed.
How well each automated flow turns a triggered send into an actual purchase.
Inbox placement, list hygiene, and opt-in status — tracked so a problem gets caught before it costs you.
Questions
You do. Everything we build — flows, templates, segments, campaign assets — lives in your Klaviyo account under your ownership, with full access at all times, not just at offboarding.
Flat monthly retainers, scoped after the free audit. No percentage-of-revenue pricing and no long lock-in contracts — you'll see the exact number before you commit to anything.
A full program review: flows and campaigns, list health, deliverability infrastructure, capture forms, and compliance exposure — opt-in records, 10DLC registration status, quiet-hour settings, and unsubscribe handling.
Flow rebuilds typically show measurable lift within 30–60 days. Campaign and testing programs compound over a quarter. We won't promise overnight ROI — anyone who does is guessing.
Not as a primary KPI. Apple Mail proxy opens inflate them badly. We report click rate, revenue per recipient, flow conversion rate, and deliverability — numbers you can actually run a business on.
Shopify is our home turf, but we work with any ecommerce brand on Klaviyo, including WooCommerce and BigCommerce stores.
