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, so your time goes to high-level thinking, client communication, and account performance rather than tedious production work. 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

Delegate copy and email uploads to junior account managers and review 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
