Replatforming and scaling on Shopify comes with real traps. Here are the ones we build around.
Sending more email doesn't help if it lands in spam. We manage list hygiene, sunset unengaged contacts, and protect your sender reputation so the messages you send actually reach the inbox and drive revenue.
Most brands lean too hard on one-off campaigns and leave automated flows half-built. We balance the two — welcome, abandonment, post-purchase, and winback flows earning in the background while campaigns drive the calendar.
Blasting your whole list trains people to ignore you. We build segments off real behavior and first-party data so the right offer reaches the right customer, and unengaged contacts get a different track.
SMS and email compete for attention when they're run in separate silos. We orchestrate them together — one message strategy across both channels — so customers get a coherent experience instead of duplicate, overlapping sends.
Klaviyo's attribution can flatter itself, and last-click misses the real story. We set up attribution you can trust so you know which flows and campaigns actually move revenue — and where to invest next.
How we grow your brand
01 · Convert
We turn dense product knowledge into buying confidence — PDPs that answer the real questions, comparison and finder tools, and CRO tested against your real traffic.
02 · Acquire
Paid search and paid social built around your margins and seasonality, not vanity ROAS.
03 · Retain
Email, SMS, loyalty, and post-purchase experiences that turn a first-time buyer into a repeat customer.

First Pier is recognized by Clutch across Shopify, ecommerce development, design, and performance marketing — nationally and here in Maine.
Both. We build and maintain the core automated flows — welcome, browse and cart abandonment, post-purchase, and winback — and run the campaign calendar on top, so revenue comes from both the always-on flows and timely sends.
Yes. We audit list health, set up sunset flows for unengaged contacts, and manage sender reputation and authentication so your email reaches the inbox instead of the spam folder.
Yes. We run SMS and email as one orchestrated strategy in Klaviyo so the two channels reinforce each other instead of bombarding customers with duplicate messages.
We set up attribution you can trust and report on flow- and campaign-level revenue, so you can see which programs drive lifetime value rather than relying on last-click or Klaviyo's default numbers.
