Definition
The email marketing team is the group of professionals responsible for planning, executing, measuring, and optimising an organisation's email communications. Core roles include the email marketing strategist (campaign planning, segmentation strategy, testing roadmap, compliance oversight), copywriter (subject lines, body copy, CTAs, transactional message content), email designer (HTML email templates, responsive layouts, accessibility compliance), email developer (ESP configuration, automation workflows, template coding, API integrations), marketing analyst (reporting, attribution, segmentation analysis, optimisation recommendations), and deliverability specialist (reputation monitoring, inbox placement testing, authentication maintenance, blocklist management). According to the 2024 State of Email Survey from Litmus, the average email team size is 1-2 full-time equivalents for companies sending under 1 million emails per month, 3-5 FTEs for 1-10 million monthly, and 6-15 FTEs for over 10 million monthly.
The decision to build in-house versus outsource to an agency depends on send volume, complexity, and strategic importance. Companies sending under 500,000 emails per month often rely on a single in-house marketer supplemented with freelance copywriters and designers. Mid-volume senders (500,000-5 million monthly) typically have 2-4 dedicated in-house staff with specialised agency partners for specific functions. High-volume senders (5 million+ monthly) almost always maintain fully staffed in-house teams because email is a critical revenue channel requiring deep integration with product, data, and engineering teams.
Best Practices
-
Define a RACI matrix for every email function: Create a Responsible, Accountable, Consulted, Informed matrix covering campaign ideation, content creation, design, development, QA, legal review, scheduling, sending, reporting, and optimisation. A RACI prevents the confusion that arises when multiple team members assume someone else is handling a critical function such as spam complaint monitoring or unsubscribe processing.
-
Invest in the deliverability specialist role early: As soon as send volume exceeds 1 million emails per month or monthly revenue exceeds £100,000, dedicate a role to deliverability. The cost of a deliverability specialist (£50,000-80,000 annually) is trivial compared to the revenue impact of a single blocklisting event, which can reduce email revenue by 30-50% for 1-3 months while recovery efforts are underway.
-
Build cross-functional workflows with IT and legal: Email team workflows depend on IT for authentication setup (SPF, DKIM, DMARC), API integrations, and infrastructure; and on legal for compliance review of promotional content, consent mechanisms, and data retention policies. Establish recurring cross-functional check-ins — monthly with IT, quarterly with legal — to prevent these dependencies from becoming blockers.
-
Develop a skills matrix and identify gaps annually: Email marketing requires skills in copywriting, design, HTML/CSS development, analytics, project management, compliance, and strategy. Assess each team member against a skills matrix and identify gaps. Common gaps in mid-sized teams are analytics (most teams underinvest in analytical capability) and deliverability (often neglected until a crisis).
-
Define career progression paths for email specialists: Retention of experienced email professionals reduces recruitment and training costs significantly. Define progression from specialist to senior specialist to manager to director, with clear skills benchmarks and salary bands at each level. Email marketing professionals with 5+ years of experience are in high demand, and organisations that invest in career paths retain them 40% longer than those that do not.
-
Match agency support to specific capability gaps: Rather than hiring a full-service agency, identify specific capability gaps in your team — complex automation builds, advanced analytics, deliverability consulting, or peak-season surge capacity — and engage specialists for those functions. This approach is typically 30-50% more cost-effective than a full-service agency retainer.

Frequently Asked Questions
A solo marketer can effectively manage a list of up to 10,000 subscribers with basic campaigns using a user-friendly ESP. At 10,000-50,000 subscribers, add a designer and consider a copywriter (2-3 total). At 50,000-500,000 subscribers, build a full team of 3-5 including a strategist, copywriter, designer, developer, and analyst. Beyond 500,000 subscribers, add specialised roles for deliverability, automation, and data engineering.
The email strategist or program manager — the person who sets the calendar, manages stakeholders, ensures compliance, and coordinates the full production workflow. Without this role, even well-staffed email teams produce inconsistent, reactive campaigns. Technical roles (developer, deliverability specialist) become more critical as volume and complexity increase.
In-house teams are better for high-volume, complex, or strategically critical email programmes. Agencies are better for low-volume, straightforward programmes or for filling specific capability gaps. The hybrid model — core in-house team with agency specialists for specific functions — works well for mid-market organisations and typically provides the best balance of control and efficiency.
Look for analytical thinking (ability to interpret data and form hypotheses), technical literacy (comfort with HTML, ESP interfaces, and basic API concepts), copywriting ability (subject lines and CTAs are the highest-impact skills), project management (multiple campaigns running simultaneously with tight deadlines), and compliance awareness (CAN-SPAM, GDPR, CASL knowledge). Industry experience is less important than these transferable skills.
Model current workload — number of campaigns per month, list growth rate, automation workflows to maintain, reporting hours required — and show the gap between current capacity and planned output. Use industry benchmarks for team size by send volume to contextualise your request. Demonstrate the revenue impact of delayed or underoptimised campaigns due to capacity constraints.
