Email Marketing Agency

An email marketing agency manages the strategy, design, copywriting, automation and deliverability of email campaigns on behalf of a brand. Enchant Agency provides end-to-end email marketing services — from auditing your current programme to building automated customer lifecycle flows and ongoing campaign management.

Email marketing agency pricing varies depending on the scope of services required. Enchant Agency offers flexible engagement models from project-based audits to retained monthly management. Contact us for a tailored quote based on your email programme size and goals.

When choosing a UK email marketing agency, look for demonstrated results (measurable revenue impact), specialist expertise rather than a generalist offer, transparency on pricing and process, platform partnerships with leading ESPs such as Klaviyo or Salesforce Marketing Cloud, and verifiable client testimonials. Enchant Agency has delivered over 1,000% email revenue growth for clients and holds DMA Award recognition.

A specialist UK email marketing agency brings immediate access to a full team of strategists, designers, copywriters and deliverability experts without the overhead of full-time salaries, benefits and training. For most brands, an agency delivers faster results and broader expertise than building an equivalent in-house function — particularly for email marketing, where platform knowledge, creative testing and compliance with UK GDPR requirements demand ongoing specialist attention.

Results vary by starting point, but UK brands working with a specialist email marketing agency typically see significant improvements in open rates, click-through rates and attributed revenue within the first 90 days. Benchmarks for well-managed UK email programmes sit at 35–45% open rates and 2–5% click rates. At Enchant Agency, we have delivered over 1,000% email revenue growth for clients by combining strategic automation, rigorous testing and conversion-focused design.

The leading UK email marketing agencies work across a range of ESPs depending on client size, sector and complexity. The most widely used platforms in the UK market are Klaviyo (particularly strong for ecommerce and D2C brands), Salesforce Marketing Cloud (enterprise), HubSpot (B2B), Dotdigital (mid-market UK brands), and Braze (mobile-first and app-led businesses). Enchant Agency holds partnerships across the major platforms and will recommend the right ESP for your specific programme rather than defaulting to a single tool.

For most UK brands, the first measurable impact from working with an email marketing agency comes within four to eight weeks — typically from optimising existing automations and improving campaign creative. More structural improvements such as rebuilding lifecycle flows, growing the subscriber list and establishing A/B testing cadences deliver compounding returns over three to six months. Enchant Agency begins every engagement with a full audit to identify the fastest-impact opportunities in your specific programme.

The 3-3-3 rule in email marketing refers to capturing attention in 3 seconds, communicating your core message in 3 sentences, and driving action with 3 words or fewer in your call to action. It is a framework for writing concise, high-converting email copy.

Reputable UK email marketing agencies build compliance into every stage of the programme — from list acquisition and consent capture through to data retention policies and unsubscribe handling. This includes ensuring all contacts are opted in under a lawful basis, that suppression lists are maintained and honoured across sends, and that data processing agreements are in place with your ESP.

Post-Brexit, UK brands must comply with the UK GDPR and PECR, which govern electronic marketing. Enchant Agency applies UK GDPR best practice as standard across all client programmes.

All you need to do is pick a subscription plan or get help with choosing from our experts and you are then free to brief as many projects as you like, whenever you like. It's that simple.

Your Enchant team are based in the UK (we are headquartered in London), Berlin and various states in the USA. We cover all timezones and serve clients globally.

Clients on our essentials plan receive account management from a variety of Enchant team members. Clients on the professional plan and enterprise plan have a dedicated account manager.

Once we've approved your suitability to work with Enchant, we can activate your account and services within 48 hours.

Over 70% of our clients renew from year 1 into multi-year working relationships because they get the ROI and value they need. We have many clients that have been with us for over five years.

The term-length that you choose with Enchant is entirely up to you. The pricing shown in our pricing tables is based on a 12-month agreement. Shorter agreements are available for all plans, but they are more expensive.

We accept direct debit, credit card and bank transfer payments. All terms are strictly 30 days in-cycle. This means that you are issued an invoice on the first day of working together and that invoice is required to be settled within 30 days. Discounts are sometimes available for clients who are happy to settle invoices ahead of time across a quarterly or annual plan.

Please note that if you fail our credit check, we may request payment in advance in order to activate your services.

We want you to get the most from working with us, so there are no limits to the number of staff you have working with your Enchant team. That said, we have found over the last 10 years that having one single point of contact to organise and agree priorities with Enchant works best.
