Email and SMS Account Manager

Job Title: Email and SMS Account Manager Location: Remote Employment Type: Full-Time Contractor Working Hours: 8 hours per day, worked within the 8:00 AM to 6:00 PM EST window (Monday to Friday) Industry: E-commerce / Email & SMS Marketing 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
