What is our approach to Email Marketing?

Our process is tailored to each client’s needs, but generally follows this structure:

1. Klaviyo Growth Audit

The first step is an audit. We look at your whole Klaviyo account; current list and segment structure, campaign plan, automation plan, forms, open rates and unsubscribe rates. From the audit we will make recommendations to improve and increase your revenue by identifying the top opportunities.

2. Email Strategy &
Lifecycle Plan

We work collaboratively with you to align your business objectives and your customer journey to build a bespoke lifecycle and email marketing plan to generate the best results for your brand. We can build an email strategy for you to manage or we can take care of delivering it from planning, designing, writing, sending, optimising.

3. Design New Email Templates

We know how to turn sends into clicks - Based on your email marketing strategy, our skilled team of designers and copywriters will create new email templates that are cohesive with your brand and get people to take action.

4. Build Impactful Messaging

We can then take care of crafting messages that cut-through to turn your email strategy into communications that convert.

Our team of copywriters can work to your existing brand guidelines and tone of voice or if you don't have one, we can craft a new tone for your email channel that complements your other marketing activity.

5. Test, Learn & Optimise

We use A/B testing with each email to learn as much as we can about our client’s subscribers. This helps us increase your open rate, your click through rate, and convert more subscribers into customers so that your business makes more money.

Through Klaviyo custom analytics and benchmarking we can determine the most effective sending times, sending frequency, and types of flows to generate the most revenue for your business.

FAQs: Still have questions about working with a Klaviyo Email Marketing Agency?

1. What is a customer lifecycle plan?

The customer lifecycle refers to the process of an individual becoming aware of a product, purchasing the product, and then remaining a loyal purchaser of the product. Long term customer loyalty is the goal for each interaction and purchase.

Did you know that it is easier and more cost effective to target previous buyers of a product rather than looking for new customers.

The customer lifecycle plan is made up of five stages: reach, acquisition, conversion, retention, and loyalty.

Email automations are the cheapest and the most effective way of targeting customers. To make life easier for you, we have compiled a list of email flows (automations) your brand should be running, give it a read here.

2. What is a Klaviyo Master Partner?

Being a Klaviyo master partner means that Altum Media is part of the Klaviyo Partner Program, specifically designed to channel growth for digital marketing agencies and their clients.

More research needed here - it’s an accreditation and demonstrates our wealth of knowledge and Klaviyo’s trust in us as a chosen Partner.

3. Why should I choose Klaviyo over MailChimp?

It’s hard to find someone in the marketing world who hasn’t heard of MailChimp and, being founded 11 years before Klaviyo, there is a simple reason why.

Whilst both check the standard boxes for email marketing tools, Klaviyo pricing is much simpler. Klaviyo grows as you grow with the distinct difference that all features are available at each level, what determines the cost is the number of subscribers. Mailchimp, on the other hand, offers four pricing packages, with the option to add individual features on each month (though some users have noted this isn’t particularly easy to do). Whilst Mailchimp may be easier to start, offering a free package, in the long run (and with the inevitable success of your automated email marketing) you’ll be needing an upgrade in no time.

Mailchimp has detailed designs that are great for marketing beginners. There is less scope for template choice but they are still fully customisable. Klaviyo offers much more flexibility. This may be a steeper learning curve for some email designers, but the opportunities to create email templates more unique and cohesive with your brand outweigh this in many opinions.

Simply put, Klaviyo’s segmentation process is taken seriously and you will be prompted to break your list down as soon as you sign up. You can segment by customer behaviour, transactions, or other information taken from CRMs (Customer Relationship Management software). This is where Klaviyo takes the lead over MailChimp, allowing you to segment your email lists based on something as specific as how many times they viewed one of your products, or people who only buy items when they are full price. MailChimp unfortunately pales in comparison, limiting its user to segments such as ‘new subscribers’ or ‘recent purchasers’.

Whilst both ESPs offer email segmentation and automation, the Klaviyo automation process is far more sophisticated and by allowing access to all features regardless of the pay package, you can benefit from this immediately. If you are a beginner, there are large scale flow templates that you can use directly, or as inspiration for your own automations. The data-analytics that Klaviyo comes with will also show you the specific route that each customer takes once opening your email, allowing you to segment customers further, if you wish.  MailChimp is less sophisticated but still reliable. There are options to use pre-existing templates or create new ones. If you are looking for basic automation then MailChimp is a great way to start.

4. What is it like working with a Klaviyo Partner?

Don’t take our word for it - here is what one of our clients said about our work -  

"We have been working with the team at Altum for just over 6 months now and from the off, we've been wholly impressed with their strategic approach to our content strategy. Throughout the process of getting them on board with our brand to develop the strategy for the year ahead, they have impressed us with their creative approach, their attention to detail and the structured way in which they manage the delivery of the activity and the monitoring and adjusting of our approach against our agreed KPIs. I would recommend them wholeheartedly."

Josie Curran, Head of Marketing

6. What should I consider when migrating ESP's?

Switching email service providers is not difficult, however, there are a couple of things that you might want to bear in mind to ensure the changeover process goes as smoothly as possible.

Time - allow enough lead time to get it right - this also includes enough time to run “warming” campaigns with your new ESP and audience.

Cost - for a period you will have to run two ESPs at the same time to reduce down-time of email marketing activity.

Templates - these might need to be rebuilt in the new ESP.

Segments - set up all the relevant segments in the new environment.
