    Email Marketing Agencies Selection Guide 

    There are many excellent email marketing agencies, offering a variety of services, to suit a wide selection of client needs. It is important to choose a good agency, but also the right type of email marketing agency for your unique needs.

    Here are the factors to look for in any good email marketing agency:

    • The services they offer and if they suit your email marketing objectives. 
    • The team and how experienced they are.
    • Customer feedback on review sites like Clutch and The Manifest.
    • Positive case studies and an excellent track record.
    • Evidence of authentic email marketing campaigns tailored to every client’s needs. 

    There are dozens of agencies that will meet and exceed your expectations when it comes to the factors above (if they don’t, move swiftly on) but that doesn’t mean they’re all going to be equally valuable to you. You also need to consider the best type of email marketing agency for your specific needs.

    Here are some of the types of email marketing agency you should consider:

    B2B Email Marketing Agencies

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

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

    B2C Email Marketing Agencies

    Like B2B email marketing agencies, B2C email marketing agencies focus only on B2C email marketing campaigns. You can work with these agencies to understand how to attract and engage targeted consumers through email campaigns. Your agency 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 email marketing 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 Email Marketing Agencies

    These email marketing agencies provide services beyond email marketing. 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 email marketing agency offers all of this and acts as a 360-degree marketing solution.

    It’s beneficial to work with full-service email marketing agencies because you can rely on one platform to achieve your objectives. You don’t need separate agencies or tools for different campaigns, making it easier to streamline your marketing efforts between all marketing channels, including email. 

    Email Marketing Automation Agencies

    Email marketing automation agencies develop automated email marketing campaigns, like drip campaigns or triggered email campaigns. For example, if a customer joins your email list, automation email marketing agencies can set an event-triggered welcome message. New subscribers are automatically introduced to your business and what you offer. Consider these agencies for high-level email marketing campaigns with a need for automation.

    Email marketing automation agencies are an effective solution for high-volume email lists because you don’t have to send newsletters for every trigger action. These agencies 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 email acquisition campaign and guide your business to maximize its awareness and leads. With extensive experience acquiring high-quality email leads, email acquisition firms know how to pin down your targeted subscribers and reach them through the right content. Because these firms take a specialized approach to acquiring email leads and nothing else, they make a worthwhile investment to accelerate your email marketing and give your business the exposure it needs. 

    Email 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 and work with email advertising agencies who will handle all these aspects for you while tracking and measuring your campaigns. 

    Email Agencies for Email Campaigns with Massive Volumes

    Developing, running, maintaining, tracking, and measuring campaigns with massive volumes of subscribers is incredibly challenging. Not only do you need a huge, experienced team and a well-equipped suite for email marketing tools, but you also need loads of time. Fortunately, many email marketing agencies specialize in projects with massive email lists. 

    These agencies can clean up your email lists, segment subscribers for targeted content, plan and create quality content and track and measure insane amounts of subscriber analytics to draw actionable insights. Your agency will handle all aspects of your campaign and work with your team to achieve your campaign objectives while building your subscribers further. 

    Platform-Specific Email Agencies 

    Platform-specific email agencies operate from platforms, offering tools and functions so you can control your email marketing. Unlike the other types of email marketing agencies, platform-specific email agencies aren’t run by people. These solutions provide end-to-end platforms so you can seamlessly manage your email campaigns, create content and track your analytics.

    An excellent example of a platform-specific email agency is MailChimp. From one platform, businesses can design strategies and use tools to acquire leads, develop customer segments, set automated emails, integrate third-party software, and collaborate with their teams virtually. 

    Email Marketing Agencies: Our Two Top Picks

    Top Pick for Enterprises

    Audience Serv for their dynamic and innovative email marketing solutions. They take all the relevant data into account in order to develop a unique email marketing strategy for each client that approaches them.

    Top Pick for Start-Ups

    Let’s Wrap it Up

    So, where do we go from here?

    Before you approach any email marketing agency, 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 marketing campaign or program. That way, when you approach an agency, you already have some goals in mind.

    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.
