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
