CodeCrew

Email marketing agency that averages 1,300% ROI. Custom programs, zero templates. Klaviyo certified, 100% agnostic..

CodeCrew is a full-service email and SMS marketing agency founded by three specialists who saw the same problem in the market: most email agencies were running templated programs and recycled strategy, optimizing for their own efficiency rather than their clients' results. We were built to be the alternative — a team that treats every brand's email program as unique, every subscriber list as worth understanding deeply, and every send as an opportunity to drive measurable revenue. Today, CodeCrew is a global team of 40+ email and SMS specialists — strategists, designers, developers, deliverability experts, copywriters, and analysts who only do email and SMS. Nothing else. That singular focus is what allows us to average 1,300% ROI across client programs, and it's what makes the difference between a program that runs and a program that compounds. What We Do We manage full email and SMS programs end-to-end: strategy, custom design, copywriting, HTML development, automation architecture, campaign management, deliverability monitoring, A/B testing, and monthly revenue attribution reporting. Every element is handled in-house by specialists. Nothing is outsourced. No templates are pulled from a library and color-swapped. Every email we send is built specifically for the brand it represents. Our services include: — Email marketing strategy and program roadmaps — Custom email design and HTML coding — Lifecycle automation and flow architecture — Campaign management and deployment — SMS marketing (Klaviyo, Attentive, Twilio) — ESP migration and platform onboarding — Email deliverability monitoring and recovery — Email marketing audits — A/B testing and optimization — Transparent revenue attribution reporting Who We Work With The majority of our clients are ecommerce and DTC brands — health and wellness, beauty and CPG, food and beverage, outdoor and sporting goods, fashion, home goods, and technology. We also have deep experience in B2B, professional services, and subscription-based businesses. Our 28+ published case studies span brands of all sizes, from emerging DTC startups to globally recognized names including Nextdoor, PetLab Co, Semihandmade, Oru Kayak, Zwilling, Maniology, LYS Beauty, and Mosaic Foods. Platform Expertise CodeCrew is platform-agnostic. We work on whatever ESP your brand uses — we don't push clients toward platforms that benefit us. Our primary platforms include Klaviyo (Silver Master certified partner), Salesforce Marketing Cloud, HubSpot, Braze, Omnisend, Attentive, Twilio, Mailchimp, Sailthru, GetResponse, and ActiveCampaign. For enterprise brands on SFMC or Braze, and for ecommerce brands scaling on Klaviyo and Shopify, we have dedicated specialist expertise rather than general platform familiarity. Results Our programs average 1,300% ROI because we build lifecycle systems, not just campaign calendars. A few examples from our case study library: Semihandmade (kitchenware/lifestyle): 700% quarter-over-quarter email revenue growth after a full platform migration from Bronto to Klaviyo and lifecycle program rebuild. Inkjets (consumables ecommerce): 1,226% increase in placed order rate following a full program rebuild. Oru Kayak (outdoor/sporting goods): 527% Black Friday and Cyber Monday revenue increase, $2.25M raised through a single Klaviyo email campaign, and 156% subscriber growth after SMS launch. The Kombucha Shop (food and beverage): Email grew to account for 25% of total store revenue under CodeCrew management. Sitka Seafood Market (food subscription): 127% increase in placed orders and 135% increase in campaign revenue. Credentials Klaviyo Silver Master Partner — verified partner status within Klaviyo's global partner program, reflecting certified platform expertise and documented client results. dotCOMM Award Winners — 2x Platinum and 1x Gold awards for email campaign design excellence, judged independently by the Association of Marketing and Communication Professionals. 24 five-star Google reviews from verified clients across ecommerce, B2B, and nonprofit sectors. How We Work Every engagement starts with a full program audit — we assess your current setup, deliverability health, active flows, list quality, and platform configuration before we build anything. From that, we deliver a documented roadmap with clear priorities and timelines. Most clients have campaigns deploying within two weeks of kick-off and core flows live within 30-45 days. You receive a dedicated account team from day one, monthly reporting that ties email performance to revenue, and a program that improves continuously through structured testing. Our Values CodeCrew has donated 1% of annual revenue to environmental causes through One Percent for the Planet since our early years, and has provided pro bono email marketing support to nonprofits including Mission Graduates and Impact Matters since our founding.
