    Common Email Marketing Services  

    An email agency is a specialized group of digital marketers who focus on email channel strategy and executions. Some common services can include below.

    Email Strategy

    This is how email as a channel fits into your overall marketing mix.

    It often starts from your email list analysis – customer segmenation based on channel engagement (openers, lapsed, etc.). Depending on how your email list overlaps your overall customer database, you might want to hone in on email acquisition within your existing customers, or focus on promotional emails to deliver targeted coupons to bring back lapsed shoppers.

    Email Analytics

    The beauty of email is you own the closed-loop data. You know exactly who you reached, how they responded to the email and your products and services, and the campaign ROI, all important email marketing metrics.

    Having an email on file also highly correlates to the customer’s lifetime value. Therefore, your email data will give you a wealth of your customer insights. A good email marketing company would help you with that process.

    Campaign Management

    Agencies can help optimize your existing campaigns and introduce new ones based on your past customer engagement data. They can include promotional campaigns, transactional emails, content marketing emails, etc. 

    A good agency will help you set up your reporting and analysis cadence, so your email channel can evolve into a continuous learning cycle.

    Marketing Automation

    This involves a full evaluation of your current Customer Relationship Management (CRM) system. This is where your customer contact data lives, to enable email, call, in-app, SMS marketing. 

    A good agency would advise on the latest technologies in the field, help you evaluate what fits your size and needs. They could also help you with migration and integration to see you on the right path to achieve seamless direct channel coordination.

    Let’s take a look at this video by LYFE Marketing to see what email marketing actually entails to get an idea of what an agency can do for you:

    There is a great deal of marketing generalists out there today, where some agencies will offer email marketing as just an add-on marketing service.

    Types of Agency 

    B2B Agencies

    They specialize in the B2B marketing environment and in B2B campaigns. They will personalize your email tactics to engage with audiences in this space.

    They are a fantastic option for B2B businesses because they understand your exact needs, and can communicate with high-valued sales reps, target profitable accounts, and create content highlighting the most essential aspects of your product and brand.

    B2C Agencies

    Like B2B, B2C agencies focus only on B2C email campaigns. You can work with these agencies to understand how to attract and engage targeted consumers. They will also determine the best frequency to promote content via email, the kind of content to market, and how to communicate your value proposition and branding.

    B2C agencies will also develop custom lead generation strategies. You can count on these firms to create targeted customer segments and help you build personal buyer relationships through email content.

    Full-service Agencies

    You can work with these firms if you need more than just email marketing. Perhaps you also need content creation, social media marketing, and specialized lead generation services. A full-service agency offers all of this and acts as a 360-degree marketing solution.

    Working with this type of agency is beneficial because you can rely on one platform to achieve your objectives, making it easier to streamline your marketing efforts between all channels, including email.

    Automation Agencies

    They develop automated campaigns, like drip or triggered campaigns. For example, if a customer joins your email list, these agencies can set an event-triggered welcome message. New subscribers are automatically introduced to your business and what you offer. Consider these agencies for when you have a series of campaigns that follow a customer’s lifecycle.

    These agencies are an effective solution for high-volume email lists because you don’t have to send newsletters for every trigger action. They may also have tools for AI email copywriting and automated lead generation.

    Email Acquisition Firms

    Gaining leads for your email campaign takes a lot of time and effort. Fortunately, email acquisition firms specialize in this! These agencies help businesses acquire targeted leads through tailored strategies.

    Your agency will develop a sound acquisition campaign and guide your business to maximize its awareness and leads. With extensive experience acquiring high-quality leads, these firms know how to pinpoint your targeted subscribers and reach them through the right content. Because these firms take a specialized approach to acquiring leads and nothing else, they make a worthwhile investment to accelerate your lead gen.

    Paid Advertising Agencies

    Although these agencies are a little uncommon compared to the rest, you might find yourself needing one! Email advertising agencies are all about advertising through email marketing. These firms will help you rent email lists, land publication features, and create content personalized to your campaign objectives and target audience.

    Email advertising is tricky, and to be successful, you must know how to manage your expenses, target the right subscribers, design your content, and share your brand voice and values. You can make this much easier by working with agencies that will handle all these aspects for you while tracking and measuring your campaigns.

    Firms Specialized in Campaigns with Massive Volumes

    Developing, running, maintaining, tracking, and measuring campaigns with massive send volumes is incredibly challenging. Not only do you need a huge, experienced team and a well-equipped email suite, but you also need to be diligent in maintaining the lists. 

    These specialized agencies can clean up your email lists, segment subscribers for targeted content, plan and create quality content, and track and measure analytics to draw actionable insights. They can also develop lifecycle campaigns to revive unengaged emails. 

    Platform-Specific Services

    Unlike others, these agencies are often brought in as the service team when you purchase email marketing software. 

    An excellent example is MailChimp. Businesses can hire professional service teams specializing in MailChimp to run campaigns, manage and maintain contacts, and connect campaigns to their eCommerce platform, among many other services.

    Let’s Wrap it Up

    So, where do we go from here?

    Before you approach any agencies, it’s best to gather all the email lists you have on hand and to make sure you have everything available and ready for them to access when needed.

    Then put together a set of clear objectives for your email campaign or program. 

    Chances are they will highlight some even greater opportunities available to you that you might not have seen or recognized before.

    Then step out and get in touch with an agency that grabs your attention the most.

    When you start using email marketing the way it’s supposed to be used – well, let’s just say you’ll never look back!
