SassySender — CRM, Retention & Email Marketing Consultancy (Klaviyo & ActiveCampaign) for Ireland, the UK & the US
We're a consultancy-first CRM and email marketing partner based in Dublin, working with ecommerce and service brands across Ireland, the United Kingdom and the United States. Specialists in Klaviyo and ActiveCampaign, we build full-funnel CRM ecosystems and personalised customer journeys that grow retention and customer lifetime value — strategy first, sending second.
What we do
We're CRM and retention strategists, not button-pushers. We map your full funnel, audit your data and tooling, design personalised lifecycle journeys, and guide your team to execute — so email compounds customer lifetime value instead of adding inbox clutter.
Our service tiers
START — CRM foundations. Data and ESP setup, customer journey mapping, domain warmup, and core lifecycle automations (welcome, abandoned cart, post-purchase).
GROW — Personalised journeys. Behavioural segmentation, RFM scoring, advanced flows, cross-channel touchpoints, and retention KPIs like repeat rate and LTV.
OPTIMIZE — Maximise lifetime value. Deep CRM audits, deliverability rescue, churn and cohort analysis, loyalty and reactivation programs, continuous experimentation.
Results our clients see

Higher repeat purchase rates and customer lifetime value through personalised journeys

Sustainable list growth without burning out subscribers
Who we work with
Ecommerce brands on Shopify and service businesses across Ireland, the UK and the US who want strategic email expertise — not another freelancer sending campaigns. Based in Dublin, working remotely with clients in London, Manchester, Cork, New York, LA and beyond.
