Reach your most engaged customers

Email marketing is cost-effective and ideal for lead generation. Very few marketing strategies focus on building trust and connection with your clients in the same way. This approach improves conversion rates and enhances your marketing success whilst protecting your brand.

We don’t believe in generic email blasts. Every client engagement starts with understanding your data, your audience, and what success actually looks like for your business. Here’s how a typical partnership runs:

Email marketing services: How we work

1. Audit & discovery

We review your current platform setup, list health, deliverability history and past campaign performance. Most accounts have quick wins waiting to be unlocked before we even send a single email.

2. Strategy & roadmap

We build a 90-day strategy aligned to your commercial goals, whether that’s revenue, lead generation, retention or re-engagement. You’ll know exactly what’s being sent, to whom, and why.

3. Build & launch

Our team handles copywriting, design, segmentation, scheduling and technical setup. A/B testing is built into every campaign from day one, not bolted on afterwards.

4. Optimise & grow

We report on the metrics that matter — open rates, click-through rates, revenue attributed and list growth — and use that data to improve every subsequent send. Campaigns get sharper over time, not stale.

Automation

Automated email sequences keep your brand front of mind, whether that’s a welcome series highlighting your brand values, a drip campaign, or transactional emails like abandoned carts. Maintaining consistent communication strengthens your relationships through perfectly timed emails, personal to each user.

We offer a comprehensive solution for email marketing that drives engagement, builds customer relationships, and delivers measurable results.

Full strategy development

  • We will conduct an in depth analysis of your business objectives, target audience, and current marketing status.
  • Develop a strategic plan that aligns with your unique business needs and KPIs.
  • Constant communication about your goals (e.g. brand awareness, sales, lead nurturing), so you can monitor your performance.

Campaign management

We will handle all end-to-end campaign management from planning, scheduling, execution, monitoring to reporting:

  • Develop detailed campaign plans with content calendars for each target area.
  • Oversee creation and deployment of emails, ensuring the highest standards for each email.
  • Through campaign monitoring in we can make adjustments for optimisation.
  • We constantly conduct A/B tests to compare email elements and maximise effectiveness overtime.

Our work

Pitchside Hospitality

Pitchside Hospitality is a luxury hospitality provider operating across multiple industries, audience types and service tiers, each requiring its own tone, timing and targeting.

We built and executed an 8-month email strategy from the ground up, covering everything from initial data cleansing and audience segmentation through to full campaign management and performance reporting. With strict data protection requirements and a diverse contact database, deliverability and compliance were as important as engagement.

The result: A 66% open rate and 75% click-through rate across the programme — significantly above industry benchmarks — achieved through precise segmentation, consistent A/B testing, and a content calendar planned months in advance.

Email marketing platforms we work with

We work across all major email marketing platforms, so you’re never locked into a tool that doesn’t fit your business. Whether you’re running e-commerce flows in Klaviyo, scaling B2B outreach through Apollo.io, or managing complex CRM workflows in Salesforce, our team knows the platform inside out before we touch your account.

Klaviyo

Our go-to for e-commerce brands. We build revenue-generating flows, including abandoned cart, post-purchase, win-back sequences and browse abandonment. Klaviyo’s segmentation depth means every send reaches the right customer at the right moment.

Mailchimp

Ideal for growing businesses that need reliability and simplicity. We handle full account setup, audience segmentation, template builds, and campaign scheduling — making Mailchimp work harder than most clients thought possible.

MailerLite

A powerful, cost-effective option for SMEs and content-led brands. We use MailerLite for newsletter programmes, lead magnet delivery, and automated welcome sequences that convert subscribers into customers.

Apollo.io

Our preferred platform for B2B prospecting and outbound email. We build targeted contact lists, manage sending domains, and run sequenced outreach campaigns that generate qualified pipeline without damaging your domain reputation.

Patch Retention

Specialist retention tooling that we use for brands focused on reducing churn and increasing customer lifetime value. Particularly effective for subscription businesses and repeat-purchase e-commerce.

Zoho & Salesforce

For businesses with more complex CRM requirements, we integrate email marketing directly into your existing Zoho or Salesforce setup, ensuring your campaigns and customer data work as one.

FAQs about Email Marketing

An email marketing agency manages the strategy, creation and execution of email campaigns on your behalf. At Roar Digital, that includes everything from platform setup and audience segmentation to copywriting, automation builds, A/B testing and monthly performance reporting — so you get results without the in-house overhead.

Costs vary depending on the scope of work, your chosen platform and the complexity of your campaigns. We work with businesses of all sizes and build packages around your specific goals, whether that’s a single monthly newsletter or a full automation programme. Get in touch for a tailored quote.

It depends on your goals. For e-commerce brands, Klaviyo is typically our first recommendation due to its segmentation depth and revenue tracking. For B2B businesses, Apollo.io or Salesforce integration often works best. For SMEs or content-led brands, Mailchimp or MailerLite are cost-effective and reliable. We’ll always recommend the right tool for your situation, not the one we prefer.

Industry averages sit around 20–25% for open rates and 2–3% for click-through rates, but our client accounts average 51% open rates and 66% CTR. The difference comes down to list quality, segmentation and relevance of content, all areas we focus on from day one.

Email automation means sending the right message to the right person at the right time without manually pressing send each time. Common examples include welcome sequences, abandoned cart reminders, post-purchase follow-ups and re-engagement campaigns. If you’re not using automation, you’re leaving revenue on the table. Most of our clients see it become their highest-performing channel within 90 days.

List growth is one of our core specialisms. We use a combination of lead magnet strategy, sign-up form optimisation, paid traffic integration and data hygiene practices to grow your list with engaged, high-quality contacts. A smaller, well-segmented list consistently outperforms a large, unengaged one.

Under GDPR, you must have a lawful basis for contacting subscribers, typically explicit consent, and give them a clear way to unsubscribe. You’re also required to store data securely and honour deletion requests. At Roar Digital, compliance is built into everything we do, from sign-up form copy to unsubscribe flows, so your campaigns are always legally sound.

Yes. While we’re based in London, we work with businesses across the UK and internationally. Email marketing is a channel that works regardless of location, and so do we. If you’re looking for an email marketing agency that can work remotely and deliver results, we’re happy to chat.
