Take Action Agency
At a Glance
Take Action Agency turns email from a cost center into a primary revenue channel for ecommerce and DTC brands by blending human strategy with AI-driven insights. As a certified Klaviyo partner, the agency builds and optimizes automated flows, segmentation, and conversion-focused campaigns that consistently raise open rates, click-throughs, and recover lost sales. If you want email to reliably replace a portion of paid ad spend and scale predictable revenue, this is the team to call.
Core Features
Take Action focuses on a tight set of high-impact capabilities: human + AI-powered email strategy, automated flows (welcome, abandoned cart, post-purchase), optimized segmentation with personalized content, and a strategic system of data-backed optimization. Every campaign and flow is designed to match brand voice and aesthetic so messaging feels native to the customer experience. Reporting and ongoing optimization are core to the offering — not an afterthought — so you get measurable lifts instead of one-off creative work.
Pros
- Specialized Klaviyo expertise: Take Action leverages deep platform knowledge to build robust automations that recover abandoned carts and increase average order frequency. This is their operational backbone and competitive edge.
- Human + AI strategy: They combine human judgment with AI insights to identify high-value segments and subject lines, making campaigns both creative and data-smart.
- Conversion-focused approach: All work is designed to drive measurable outcomes — higher open and click rates, increased order volume, and improved customer lifetime value.
- Seamless brand integration: Emails are crafted to honor your brand voice and aesthetic so sequences feel native and drive stronger engagement.
- Ongoing partnership and transparency: Clients receive regular reporting and continual optimization rather than set-and-forget deliverables, creating long-term growth rather than short-term spikes.
Who It’s For
Take Action is ideal for ecommerce brands, scaling startups, and DTC businesses that already recognize email as a growth lever — or those ready to make it one. If you use Klaviyo (or plan to) and need automated systems that scale revenue reliably, this agency fits. It’s particularly strong for teams that want a strategic partner to run flows, manage segmentation, and translate analytics into creative, conversion-driven campaigns.
Unique Value Proposition
Take Action’s unique value is its singular focus: converting email into a predictable revenue channel through a hybrid of expert human strategy and AI optimization, anchored by Klaviyo proficiency. Unlike agencies that scatter across dozens of tools or sell isolated campaigns, Take Action engineers end-to-end systems — automated flows, precise segmentation, brand-aligned creative, and continuous data-driven iteration — that compound over time. That systems-first mentality means faster recoveries of abandoned carts, consistent increases in repeat purchases, and measurable reductions in dependence on paid ads. In short: they don’t just send emails — they architect a revenue engine that grows with your brand.
Real World Use Case
A client working with Take Action saw revenue increase by 272% after the agency rebuilt their flows, refined segmentation, and executed consistent campaign management. Abandoned cart recovery, timely post-purchase sequences, and tailored re-engagement emails combined to transform email into a profitable, scalable channel.

Email Uplers
At a Glance

With a large internal team and flexible engagement models, it’s built to move quickly on medium-to-large projects for brands and agencies. That scale is a strength for complex needs, but it can feel like overkill for very small teams with simple requirements.
Core Features
Email Uplers provides complete email marketing execution: responsive and modular template design, campaign setup and management, automation workflows, and related assets such as banners and landing pages. The team includes over 150 full-time email marketing professionals and supports more than 50 ESPs (including Salesforce Marketing Cloud, Mailchimp, HubSpot, Braze, Klaviyo, and Marketo).

- Flexible pricing models: Options like project-based pricing, wallet models, or dedicated teams let you choose the engagement style that fits your budget and timeline.
Cons
- Can be overwhelming for small businesses: The breadth of offerings and scale of the team may be more than what very small brands need.
- Variable pricing requires quotes: Costs depend heavily on scope and complexity, so you’ll need detailed quotes to understand true budget impact.
- Reliance on an external vendor: Outsourcing campaign execution and assets means you depend on a third party for timely delivery and brand fidelity.
Who It’s For
Email Uplers is best for businesses and marketing agencies that need a reliable, fast, and technically skilled email partner—especially teams that run frequent campaigns, require multi-ESP support, or want a dedicated resource model. If you manage complex templates, automation, or need consistent production capacity, this agency fits well.
Unique Value Proposition
Email Uplers’ distinct advantage is its combination of full-service capability and scale: a large, specialized team capable of designing responsive, interactive templates and executing campaigns across dozens of ESPs with quick turnaround options and flexible engagement formats.

- Proven track record of increasing revenue and ROI for clients: The agency highlights measurable uplifts that make their services directly accountable to business outcomes.

- Comprehensive insurance for peace of mind: Coverage for cyber, media, and liability risks reduces operational exposure when an agency manages customer communications.
Cons

- Focus primarily on ecommerce brands, may not suit non-ecommerce businesses: If you’re outside DTC or retail, the methodologies and KPIs may be less relevant.
- Details on specific pricing plans are not provided upfront: You’ll need to request a quote to understand exact costs, which makes quick vendor comparisons harder.
Who It’s For
