An email marketing agency is a firm or company that specializes in the development, execution, and management of email marketing campaigns.

Email marketing is one of the most effective marketing channels today. The channel has an extremely good ROI of around 3800%, according to DMA. That essentially means that for every £1 ($1.27) spent on email marketing, you can expect to get back  £38.33 ($48). 

However, your strategy must be spot-on for you to get those results. You’ll need the expertise to design and write engaging newsletters. You must also leverage email marketing techniques like segmentation and A/B testing to optimize your results.

That’s where an email marketing agency comes in handy. For a good number of organizations, hiring an email marketing agency makes more sense than hiring an in-house team. 

Read on to see how partnering with an agency can benefit your company and whether you’re better off with an agency or doing it in-house. 

Benefits of hiring an email marketing agency

An email marketing agency brings a lot to the table. Here are some of the top benefits of outsourcing your email marketing:

  • Expertise and experience – Email marketing agencies specialize in email marketing. That means they’re always updated with the latest email marketing trends and best practices. Their businesses depend on it! As such, hiring agency email marketing firms ensures you’re getting nothing but the best for your email campaigns.  This can be especially beneficial for small-to-midsize companies that can’t afford to hire a full-time email marketer and equip them with all the resources they need. It can also benefit solopreneurs who are forced to wear many hats but may not have the time to execute effective email marketing campaigns
  • Access to advanced tools and technologies – Since most agencies specialize in a particular field, they must invest in the best resources to ensure they can deliver the best services to their clients. Therefore, you can expect the best email marketing agencies to have cutting-edge tech for running email campaigns. That includes email marketing platforms for sending emails, design tools for creating stunning templates, automation software for automating some email campaigns, and analytics tools for tracking performance. Email list building and A/B testing solutions are also vital for successful email campaigns. The good news is that email marketing services like GetResponse allow marketers to access most of these tools from one platform. Still, you must review the agency you want to partner with to see what tech they use to determine whether it’s enough to get the best results. Don’t worry. We’ll show you how to choose the ideal agency email marketing firm.
  • Saves time – Email marketing is extremely beneficial, but it takes time to build and execute an effective strategy. You must invest time in building tools like lead magnets for email collections. You need even more time to write and design engaging emails. There’s also tracking of results and tweaking your strategy. The whole thing takes a lot of time, which some organizations may lack. Outsourcing email marketing takes the burden off your team’s shoulders, allowing them to focus on other, more critical tasks, such as closing deals.
  • Cost-effective compared to an in-house team – The truth is that effective email marketing requires more than one expert. Sure, some folks can wear several hats, but if you want the best, chances are you’ll need to hire at least two experts: a designer and email marketing strategist. Depending on the skill set of those individuals, you may also require an email copywriter.That means you may end up with up to 3 full-time hires doing just email marketing. Then, you have to factor in other costs for stuff like the email marketing platform you’ll use. These expenses can add up quickly and get very expensive. An email marketing agency has these and other experts on their payroll. Partnering with them becomes a lot cheaper because you get access to all the experts without paying the full price for each of them. These email service providers can afford to provide their expertise at an affordable rate due to economies of scale. 

The case for outsourcing email marketing is strong, but you must know exactly what you want and do your homework when hiring an agency. 

Services offered by email marketing agencies

You’ve seen what are email marketing agencies and the potential benefits of hiring one. Let’s now look at the services you can expect from them.

Email campaign strategy development

Email marketing agencies will help you create an effective campaign strategy that aligns with your business goals. Now, you must first work together on a strategy call where you’ll explain what exactly your business hopes to achieve from email marketing campaigns.

The agency will then use that to develop a strategy that aligns with those goals. They’ll determine what email campaigns are right for your specific needs. For example, if the aim is to build customer loyalty, newsletters may take priority over promotional emails.

On the other hand, if your primary goal is to increase sales, promotional emails will likely be the focus. 

Besides deciding what emails to use, the agency will also work on the type of content, timing, and frequency of sending those emails. They might also create unique campaigns for specific seasons like holidays, black Friday, cyber Monday, etc. 

List management and segmentation

You can’t run successful email campaigns without effective list management. You have to get your email list right first! An agency can help you with that.

The agency will start by auditing your email list. They’ll pinpoint inactive or invalid email addresses that could affect your email deliverability and sender reputation. Next, they’ll look at how you’re capturing those email addresses. This is really important because if you’re collecting emails of the wrong people, converting them will be next to impossible.

Therefore, the agency will audit your email collection strategy and make the necessary changes to ensure you only capture the emails of folks who could benefit from your services. For example, they may change the lead magnets you use if they don’t align with your service offerings. 

Next, they must segment your list to deliver tailored messages. They’ll come up with the relevant segmentation criteria and create a unique content strategy for each group. 

For instance, they may create a separate segment for the contacts in your digital address book that you acquired through digital business cards. You can even create several segments from this book depending on how they interact with your digital business card. 

The agency can also segment subscribers based on behavioral traits like purchase history.

Even more important, they’ll monitor the segments regularly to ensure they remain relevant.

Finally, the agency will make sure the email list-building strategy is compliant with the latest data protection laws like GDPR and CAN-SPAM.

Email design and content creation

The only way to capture your subscribers' attention is through effective email design and content. A great design and compelling content will ensure email recipients read through your email and get to your calls to action (CTAs).

An email marketing agency will take care of this because they typically have expert email designers, content strategists, and copywriters. 

In addition to increasing your email engagement rates, they’ll ensure subscribers are always looking forward to your emails, which will drive higher open rates and click-through rates for future campaigns. 

Automation and workflow setup

Modern email marketing requires automation. This is the only way to ensure you reach subscribers at the right time with the right message.

The agency you partner with will set up the necessary triggers to ensure the right campaigns are deployed at the correct time. 

For example, they’ll create a welcome email workflow and set up the trigger for when new users sign up to your email list.

They can also set up cart abandonment triggers for eCommerce stores or free trial workflows and triggers for SaaS brands. 

Every business will require several automation workflows for different campaigns. Agency email marketing firms will identify the right ones for your company and set them up for you.

Analytics and reporting

Finally, you have analytics and reporting, which is where email marketing experts determine whether the strategy is working. The agency will analyze this data and create an easy-to-understand report for you. 

The report should show how the email marketing strategy performs and whether it brings you closer to your business goals. 

How to evaluate and choose the right email marketing agency

Now for the most important bit: how do you hire an email marketing agency? What items should you keep in mind when hiring an agency email marketing firm to ensure you’re getting the best experts for your company? 

Follow this 5-step guide:

1. Define your email marketing goals

You can’t pick the right partner for any function of your business if you’re not sure what you want or hope to achieve from the partnership. That’s why the first and perhaps most important step of hiring an email marketing agency is determining your goals. 

What do you want to achieve with your email campaigns? Do you want to boost all aspects of your business, from increasing customer loyalty to driving more sales and getting more customer referrals? Or perhaps you’re only focused on one aspect, like reducing the cart abandonment rate or boosting customer lifetime value (CLV)?

Whatever the case, make sure the goal is clear before contacting any email marketing agencies. It also helps if you can have specific KPIs in mind. 

These details will help you pick the right partner that aligns with your business goals. Clear goals will also make it easier to determine whether the partnership works or not. For starters, knowing the goal helps you identify the relevant metric to track. 

Secondly, you can come back several quarters after outsourcing your email marketing to determine whether the strategy is hitting its mark. 

2. Evaluate their expertise and services

After writing down your goal (or goals), it’s time to create a short list of potential email marketing agencies. You can find these agencies by simply searching them on Google. You can also find relevant firms on business directories like Clutch.

With that list ready, go through every agency looking at the services they provide. Most of the time, you’ll find agencies provide end-to-end email services. That means they’ll help with everything from email list building and segmentation to strategy development, execution, and reporting. Those are full-service email marketing agencies.

Still, just make sure they provide the specific services you’re most interested in.

Next, ask important questions like what industries they specialize in, how they build an email marketing strategy, can they share examples of strategies they’ve executed in the past,  and how they ensure compliance with GDPR and the CAN-SPAM act.

You also want to know what tools they use, the reports and insights they’ll be providing, and how the process works (will they need to integrate their solutions with any of your company’s systems). For example, will they need access to your Google Analytics 4 or an integration to your CRM?

3. Review case studies and client testimonials

It’s not enough to hear from the agency. You must do your own due diligence to confirm their expertise and capabilities. That means reviewing both the case studies published on their site and reaching out to past clients.

This should give you an idea of what it’s like working with the agency and the results you can expect. To get accurate insights, try to find clients in the same industry as you. That’s because email marketing campaigns can take different forms depending on the industry and target audience. 

For example, B2B email marketing tends to be very different from DTC and B2C email marketing. Similarly, you can expect eCommerce email marketing to be quite different from SaaS email marketing. 

4. Assess their reporting and analytics capabilities

Email marketing has one of the highest ROIs of any marketing channel. However, you’ll only realize that ROI if you make data-informed decisions. This is why picking an agency with advanced reporting and analytics capabilities is critical.

Go beyond the basic metrics like open and click rates. Granular reports with insights on things like heatmaps, scroll-depth, and ROI attribution will be essential for your success.

You also want to know how the agency uses the insights to create actionable recommendations. How do they interpret the data, and how do they use those insights to tweak your strategy? You can ask how they did this in a real-life scenario involving their past or existing clients.

Also, just because you’re asking about reports and analytics doesn’t mean they should confuse you with industry jargon or share confusing reports. The best email marketing agency will explain things in a way that you can understand and share informative data visualizations.

5. Consider their contract terms

Finally, go through the contract terms and make sure it’s something you can work with. 

Here, you want to know how long the contract runs and the termination procedure. 

Like any other marketing strategy, email takes time to produce results. Still, the contract should provide a way out in case the agency fails to hit the agreed KPIs.

It’s also important to consider things like who owns the audience data, email templates, and content. Also, look at the scope of services, transparency on pricing, and communication and collaboration procedures (how often should you expect progress reports and what do they need from your end). 

Email marketing agencies FAQs

1. When should you consider hiring an email marketing agency?

You should consider hiring an email marketing agency when you don’t have the right expertise in-house or don’t have enough time to execute an effective strategy. You can also hire an agency if your current strategy isn’t producing any results or when you want to scale quickly.

2. Who should hire an email marketing agency?

Growing companies that lack in-house experts should hire an email marketing agency. Also, companies with low conversion rates and marketing teams with heavy workloads can benefit from partnering with agency email marketing firms.

3. Email marketing agency vs freelancer vs in-house employee: which is right for your business? 

Email marketing agency is right for organizations that want comprehensive and scalable email services. Freelancers are ideal for small businesses with a limited budget. In-house employees are ideal for companies that want direct control over their email campaigns and have enough budget. 

4. Where to find a reliable email marketing agency? 

You can find a reliable email marketing agency from business directories like Clutch. You can also simply search on Google. But make sure to vet the agencies thoroughly before signing on the dotted line.

5. How to effectively collaborate with an email marketing agency?

To collaborate with an email marketing agency effectively, communicate your goals clearly and share enough background information. You should also maintain open lines of communication with the agency and be receptive to their recommendations. Avoid micromanaging, too.

Conclusion

An email marketing agency is a firm that provides outsourced email campaign services to businesses that cannot run in-house email campaigns. Partnering with this agency gives you access to their expertise and can be more cost-effective than hiring the experts in-house. 

To partner with the right agency, determine your email marketing goals, vet the agencies you’ll shortlist, review client testimonials, assess their reporting skills, and analyze the contract terms. 

If you’re too busy to run email campaigns or have been seeing poor results from your strategy, partner with an agency to get expert help. Good luck!
