About Us

Mint Source is a remote-first bridge that connects vibrant talent with international clients and agencies, enabling skilled individuals to showcase their expertise on a global stage.

Role Overview

Mint Source is hiring an Email and SMS Account Manager to join an email and SMS marketing agency that helps e-commerce and B2B brands grow through data-driven campaigns, flows, and lifecycle strategy, with a strong footprint in telehealth and supplement brands. This is a client-facing, strategy-first seat: you'll own the relationship and direction for a portfolio of accounts, lead weekly calls with clients and the internal team, and keep the creative team stocked with clear, well-briefed tasks. Implementation support sits with junior team members, though some clients prefer the account manager they speak with to upload their emails, so expect to be hands-on in the platform for those accounts. Beyond that, your time goes to high-level thinking, client communication, and account performance. This role is the hub of the agency, where client trust, team output, and retention all come together.

What You'll Do

• Manage a portfolio of email and SMS client accounts with varying levels of involvement, from high-touch strategic relationships to light maintenance accounts, starting with around 8 accounts and growing week by week to 10+ at full capacity
• Lead weekly calls with clients and with the internal team supporting your accounts
• Set the strategy for each account, including campaign calendars, flow priorities, and side projects
• Create and brief tasks for the creative team in ClickUp based on each client's workload
• Read and interpret performance data across Klaviyo, Omnisend, and other email platforms to guide account decisions
• Upload emails hands-on for the clients who prefer their account manager to handle it, and delegate copy and the remaining uploads to junior account managers, reviewing their output
• Keep clients updated with proactive, structured communication over Slack and regular meetings
• Monitor account health, spot risks early, and act before they become retention problems
• Stay current on email and SMS trends and bring fresh ideas to your accounts

What We're Looking For

• 3 to 5 years of experience managing client accounts in email, SMS, or lifecycle marketing, ideally agency-side
• Experience handling multiple client accounts at once and a clear understanding of what it takes to keep that many relationships healthy
• Hands-on familiarity with Klaviyo, Omnisend, HubSpot, ActiveCampaign, and most major email platforms
• Comfortable working across Slack, ClickUp, and Figma
• An understanding of what it takes to scale a DTC brand, with the flexibility to apply email thinking to non-ecommerce clients too
• Experience with telehealth or supplement brands is a strong plus. Both come with compliance considerations and customer journeys that reward account managers who already know the terrain
• An outgoing, proactive communicator who stays resilient and calm under pressure
• Strong attention to detail paired with creativity and problem-solving
• A plus, not a dealbreaker: hands-on design skills for same-day edits, an eye for design, and case studies or a portfolio of past client work

Key Performance Metrics (KPIs)

• Maintain solid client retention across your portfolio
• Demonstrate command of marketing data and overall digital marketing, using performance insights to drive account decisions
• Keep the team you manage consistently briefed, so everyone always has clear work in the queue
• Run client and internal calls that leave both sides aligned on priorities and next steps
• 30/60/90: begin with a small pod of accounts during training, take on additional clients weekly as you ramp, and progress from supervised handovers to independently managing a full portfolio of 10+ accounts

What You Get

• Competitive compensation discussed individually based on experience and location
• A fully remote role with a 50/50 balance of collaboration and independent ownership
• Regular structured feedback through weekly and monthly check-ins
• Real growth headroom as the agency scales and your portfolio grows
• Back-office support from Mint Source for payroll, onboarding, and HR
