SassySender — Email Marketing Consultancy (Klaviyo & ActiveCampaign) for Ireland, the UK & the US
We're a consultancy-first email marketing agency 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 email strategies that actually convert — strategy first, execution second.
What we do
We're email marketing strategists, not button-pushers. We design the playbook, audit your account, build the roadmap, and guide your team to execute it — so email becomes a real revenue channel instead of a guessing game.
Our service tiers
START — For new brands. ESP setup, domain warmup, foundational flows (welcome, abandoned cart, browse abandonment, post-purchase), and a content calendar to launch with confidence.
GROW — For established brands ready to scale. Advanced flows, segmentation strategy, list hygiene, A/B testing frameworks, and revenue optimisation.
OPTIMIZE — For brands fighting deliverability issues, spam complaints, or stagnant revenue. Deep audits, deliverability rescue, and performance turnaround.
Results our clients see
Email becoming a top-3 revenue channel within 90 days
Significant lifts in flow revenue through better segmentation
Recovered deliverability for senders stuck in spam
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.
