Email & Lifecycle Marketing

Email and lifecycle marketing is the work of converting acquisition spend into recurring revenue — the post-purchase, post-trial, post-signup work that separates programmes with strong unit economics from programmes that burn cash on every customer they win. The conversation about marketing usually focuses on acquisition. The conversation about whether marketing is profitable usually focuses on retention. We run both — but this service is specifically the retention side.

What this service covers

The standard programme covers:

• Email marketing: campaigns, newsletters, broadcast sends — strategy, copy, design, deliverability, list hygiene
• Marketing automation: triggered flows based on behavioural signal (signup, purchase, abandonment, milestone, churn risk)
• Lifecycle journey design: welcome flows, onboarding sequences, activation programmes, retention triggers, win-back campaigns, reactivation
• Loyalty and advocacy: referral programmes, ambassador outreach, customer-led content
• SMS and push (where appropriate) — channel-agnostic lifecycle execution under one strategy
• Customer data infrastructure: CDP integration, audience segmentation, lifecycle stage taxonomy
• Measurement: LTV cohort analysis, retention curve modelling, blended ROAS contribution from retention

Why retention is the leverage point most programmes underweight

Acquisition gets the budget; retention gets what's left. The economics of that allocation usually don't survive scrutiny.

Two specific patterns repeat:

1. First-purchase economics are barely profitable, sometimes loss-leading. Real margin sits in repeat purchase, expansion revenue or referral. Without lifecycle work, that latent margin doesn't materialise — customers churn before reaching it.
2. LTV is the variable that determines acceptable CAC. Higher LTV means you can outbid competitors on acquisition. Marketing programmes that don't actively work on LTV are leaving the most leveraged variable on the table.

Boston Consulting Group's research on growth investment consistently shows that LTV improvements compound — a 10% lift in LTV typically enables 10-15% higher acquisition spend at constant payback, which compounds further as more customers enter higher-LTV cohorts. The work pays back faster than acquisition optimisation in many programmes.

How the lifecycle programme runs

Why this paired with paid acquisition is more efficient than either alone

What it costs

Lifecycle programmes are typically priced as a fixed monthly retainer (not as a percentage of media spend, since most lifecycle activity has no media cost). Pricing reflects the complexity of the lifecycle architecture and the volume of campaigns + flow maintenance:

• Maintenance / lower-complexity programmes (existing flows, modest campaign volume): from £3,500/month
• Standard programmes (full lifecycle architecture, 4-8 broadcast campaigns/month, ongoing flow optimisation): £6,500-£14,000/month
• Comprehensive programmes (multi-product or multi-region lifecycle, advanced segmentation, SMS + push integration, advocacy programmes): £12,000-£28,000/month

Where this service wins

• Subscription businesses (SaaS, consumer subscription, membership) — where LTV improvement compounds across the recurring revenue base
• Ecommerce with material repeat-purchase behaviour — where lifecycle work captures the gap between first-time and repeat-customer LTV
• B2B services with multi-product expansion or repeat-engagement potential — where post-engagement nurture turns into expansion revenue
• Programmes with strong acquisition but weak retention curves — usually a lifecycle problem dressed as a product problem
• Brands that have hit a CAC ceiling on paid acquisition — lifting LTV is the path to making higher CAC profitable

Where it doesn't fit

• Pure-transactional businesses with no realistic repeat or expansion path (one-off purchases with low referral potential)
• Brands with acquisition that's so weak the lifecycle architecture would be optimising against insufficient cohort volume
• Programmes with no first-party customer data infrastructure — the work depends on knowing who customers are and what they've done
