Not sure where to begin when selecting the best email marketing services for clients? We’ve got you covered!
Why email marketing is important for your marketing agency
You may wonder: Should my agency even invest in email marketing software? It may seem like an extra platform to learn the ropes of, but it’s absolutely vital for long-term success and meeting client needs.
With over 4.2 billion email users worldwide, the possibilities for customer outreach are endless, and you wouldn’t want to waste time because of a lack of process.
The most important aspect of email marketing is the ability to share highly targeted campaigns. Potential customers are at different stages of the buying cycle. Some may be in the consideration stage, while others may be at the research and compare stage, and even others in the ready-to-purchase stage.
Having the ability to segment your audience and create buyer personas can help you determine what kind of content to create for each step. Segmenting these customers into appropriate email marketing lists helps businesses target these groups more effectively.
Customers need information to move them to the next buying cycle stage; pushing the right content can do just that. It's all about moving these prospects down your sales funnel - not as quickly as possible, but as efficiently as possible.

Make 2026 your best client acquisition year yet.
And with consumers spending an average of just 10 seconds reading branded emails, it’s especially important to send visually aesthetic and well-timed email campaigns that improve overall client campaigns while avoiding common cold email mistakes.
Here’s a detailed breakdown of why an email marketing service will benefit your agency and keep clients happy.Â
1. Efficient management of customer databasesÂ
After you’ve put in the work to capture client lead data, what will you do with it? It makes no sense to store that golden information in something as non-scalable as a manual spreadsheet, and while a free email marketing service may seem tempting, they often lack the functionality that a professional marketing agency requires. Â
Setting aside the appropriate budget to cover the cost of email marketing software will most often provide a significant return on that investment. Use our list of tools for marketing agencies to prioritize what’s worth paying for.
Too often - because it's low cost - people just go through the motions and make little to no attempt to differentiate their campaigns.
Give it as much if not more care & attention than other more expensive marketing channels.
Not only does this open your agency up to human error (on top of additional, painstaking hours to copy and paste that information), it isn’t a viable solution if you're looking to grow–unless you’re a fan of spreadsheets with a million tabs.
Besides, it doesn't make sense for all that valuable data just to sit there without offering real insight that helps you to understand what’s happening, performance-wise.
A robust email marketing platform gives you access to audience demographics, data visualization, and other valuable capabilities. That way, you’ll be better positioned to make future recommendations to your client and report on data-informed insights.
In fact, a recent study found that for every $1 that’s spent on email marketing, marketers see an average of $36 ROI.
That means that your agency should view an email marketing tool as a win-win, strategic investment that not only meets client needs but also drives revenue.Â
3. Customizable templates and visually appealing designs
What catches your attention more–a heap of text in an e-mail or a well-designed template with stunning visuals and media?
Having a proper solution in place means you’ll be able to create and customize email newsletters in a palatable, visually appealing way. After all, that’s what this type of software was made for.
Solidifying your client’s marketing collateral and brand aesthetic will also go a long way in establishing loyalty and building recognition.

As subscriber lists grow, so do their data subsets and audience segments. You don’t want to overgeneralize newsletters when there are opportunities to speak specifically to different types of subscribers.Â
Segmentation is a powerful tool because it allows you to target specific subsets within your client’s audience or even trigger emails based on specific behaviors or actions.
We work with organizations in the social sector, and email is a critical tool for inspiring action including things like event registration, fundraising, volunteering, and advocacy.
The key is consistently delivering content that matters to your audience. This often means your content needs to be valuable to the individual requiring considering how to personalize your email marketing.
If someone just donated last week, you don't want to send them another email ask as if they never donated. You want to send them a thank you, share the impact they are making, and invite a next step that is appropriate with consideration for their recent gift.
That way, you customize correspondence based on the email marketing customer’s journey and increase the likelihood of favorable actions (such as opens, clicks, downloads, or online transactions, for example). With a segmented audience, you’ll be able to tailor-make offers, exclusive deals, incentives, and discounts.Â
5. Granular, data-driven level understanding of your audience
Successful marketing campaigns are data-driven, and email marketing is no different. When your agency invests in the right software, you’ll see exactly who opens your client’s emails, what actions they take, which links are most clicked, and even the most engaged followers according to geographic region.
Email is often about driving traffic to other brand destinations. You may promote content or products on your website or social profiles for example. As such, having email metrics integrated into other metrics such as your website are hugely helpful. Using UTM codes in your links is a helpful way to make a connection between emails and other target destinations.
Armed with these insights, you visualize what’s happening and uncover previously uncharted audiences or new email marketing opportunities. To present these findings clearly, use one of our email marketing report templates to showcase results in a client-friendly format.
Having data is a superpower–be sure to equip your agency with it by using email marketing software that provides it.
When subscribers opt in to receive your client’s emails, they’re already engaged (to varying degrees), aware of your client’s brand, and interested in further correspondence. With that current level of brand awareness, the possibilities are endless when it comes to marketing, as it’s already covered some of the groundwork.
Great emails are a conversation. The only way to assess how what you are saying is perceived is by studying the reactions to your email. Whether someone clicks, shares, and/or replies are the "facial expressions" and "words" that a person shares back that can tell you how well your conversation is going.
Because you have these subscribers’ attention, you need a way to keep the interest going and build it further over time. By mapping the customer journey and creating effective tactics (such as drip campaigns), email marketing will keep your client’s brand top-of-mind.Â
And let’s be real–the competition is fierce when it comes to driving brand engagement and fostering loyalty. To increase the chances of email marketing success, keep content relevant and understand who you’re marketing to. That way, you’ll increase the impact of your client’s email marketing and get the most from their campaigns.
What to consider when choosing email marketing software for your agency
It goes without saying that marketing automation is one of the keys to agency (and client) success. Not only does it save you time in the long run, but it also increases efficiency and results in one less thing on your marketing plate.
But before delving into a decision, here are a few questions to consider:
1. What are the overall expectations when it comes to email marketing?
Do your clients have a vision or expectation for email marketing campaigns? Maybe it’s a beautifully designed template that shares the latest updates from their business, or maybe they’d value designs that facilitate ecommerce email marketing.
Or does your agency have a specific use case that needs to be executed, such as an email nurture stream to turn a cold lead into a hot sales prospect?
Whatever the email marketing strategy, choose an email marketing service that best fits most (if not all) of your client’s needs. That way, you’ll set a standard and meet expectations from the get-go.
Agency Tip: Before onboarding a new client or offering email marketing services to an existing one, have a 1:1 chat to understand what they’re looking for. In addition, evaluate any existing brand collateral to get a feel of their aesthetic and who they’re marketing to. You can also follow this email marketing checklist for agencies to ensure nothing gets overlooked.
How many subscribers does my agency need to manage?
This is an important consideration, as it’ll help you to decide which email marketing tool fits your current situation best.
Evaluate how many email subscribers each of your clients has to get an idea of what contact capacity works best. Based on this, explore options and also consider the financial implications (i.e., how much an email marketing service increases as new subscribers are added).
By mapping this information out, you will narrow your options and select the most efficient, cost-effective option.
Agency Tip: Work with your client to estimate their average subscriber growth per month so you’ll have a better understanding of their future needs. This will help you to plan ahead and decide on the most appropriate option.
3. Does your agency need an email marketing service with app integrations?
Email marketing is dynamic and often depends on other integrations for maximum impact (e.g., targeting email subscriber lists through Facebook Ads or Google Ads). Use this insight to narrow down email marketing software and choose the option that most aligns with client needs.
That way, you won’t be stuck in an unfavorable situation later on (such as migrating to another email marketing service or realizing that you lack the capabilities that a prospective client is looking for).
4. What type of data does your agency and clients value most?
When the end of the month rolls around, what types of results do clients typically ask for? Perhaps it’s an understanding of email marketing engagement metrics, or maybe they are most interested in tracking revenue. Whatever the case, use this information to evaluate what type of reporting information you’ll need from email marketing software.
Agency Tip: Use email benchmarks to measure your client’s performance compared to others in their industry. That way, you’ll have a better gauge of how their average performance compares to their peers and whether they’ve hit the mark or not. It also sets a realistic goal to aspire towards (or even surpass).Â
5. Does the email marketing software integrate with your agency’s reporting processes?
Consider your current reporting process and how well email marketing software for agencies will tie into it. For example, you wouldn’t want to decide on a service only to realize it hampers your entire reporting process because of a lack of automation or integration capabilities.Â
Most reporting platforms don't have the ability to include data from all components of a digital campaign. It was important for us to be able to measure and report on SEO, socials, paid search, CRM (leads), email marketing, and so on. The ability to do this and collate all the data in one central report is critical for our clients.
With an email marketing analytics report from AgencyAnalytics, integrating email marketing data is simple, time-saving, and easy to set up. That way, you won’t have to worry about manually sourcing analytics.

6. Do you need more than one email marketing platform?
A top marketing agency typically needs more than one email platform to serve its diverse client base. Even the best email marketing platform has limitations when it comes to serving very different client needs, and most email marketing platforms cater to specific use cases. One platform may be designed for the needs of large companies and high spenders, while another may cater to small businesses with a smaller marketing budget.
Some platforms, such as HubSpot, are better suited for an integrated email, CRM, and sales management process. In contrast, others, like Drip or Klaviyo, or other email marketing platforms built for ecommerce, would be better suited to creating visually appealing nurture streams for online stores.
Most agencies will work across multiple email platforms based on their internal needs and expertise, as well as their clients' requirements.
Even if your team deals with multiple platforms, it's essential to understand how they work together and with your reporting processes.

Frequently asked questions about email marketing software for agencies
Clear guidance to help your agency choose smarter tools, streamline reporting, and deliver stronger client results.
Email marketing software for agencies must support multiple client accounts, streamline workflows, and offer clear visibility into campaign performance. Unlike tools built for single businesses, agency-friendly platforms prioritize multi-user access, client-specific permissions, and advanced automation that scales across accounts.
Strong segmentation, customizable templates, and integrations with other marketing platforms are essential to support diverse client needs. The best email marketing software for agencies also includes robust analytics, allowing you to measure performance, attribute revenue, and optimize client campaigns without jumping between dashboards.
Bonus points if the tool integrates seamlessly with AgencyAnalytics for centralized reporting.
Choosing the right email marketing software depends on each client’s goals, list size, ecommerce needs, and level of automation required. Ecommerce brands often benefit from platforms like Klaviyo or Drip with advanced segmentation and behavioral triggers. Service-based clients may prefer platforms with an all-in-one CRM, such as HubSpot or Keap.
Agencies managing multiple clients should also evaluate pricing models—some platforms charge by contacts, others by send volume—as well as the availability of automation workflows, A/B testing, and SMS marketing.
Ultimately, the right email marketing platform for agencies balances flexibility, scalability, and ease of use, making it easier to manage campaigns across many client accounts.
Key features for marketing agencies include drag-and-drop email builders, customizable templates, advanced automation workflows, and powerful audience segmentation. Tools with multi-user access, detailed analytics, and the ability to manage multiple platforms or client accounts in one interface are particularly useful.
Ecommerce agencies may require dynamic product feeds, transactional emails, or integrations with top ecommerce platforms like Shopify or WooCommerce. Other valuable capabilities include SMS campaigns, AI writing assistants, predictive analytics, landing page builders, and behavior-based triggers.
Above all, agencies should look for platforms that simplify client campaigns and reduce friction across teams—especially when managing large amounts of customer data.
Often, yes. Most email marketing platforms excel in specific areas—ecommerce automation, CRM management, enterprise-level customization—so agencies serving diverse industries rarely rely on a single system.
For example, ecommerce clients may need advanced segmentation and product-based automations, while B2B clients may need CRM integrations and sales tracking. Using multiple client accounts across different tools allows agencies to tailor services without forcing every client into the same system.
The key is ensuring each platform integrates smoothly into your reporting workflows, especially if you use AgencyAnalytics to consolidate metrics from many email providers into a single reporting environment.
The best email marketing software for agencies centralizes assets, automations, and analytics across multiple clients, reducing manual work and improving consistency. Multi-account management allows teams to toggle between client profiles, assign permissions, and organize campaigns without mixing data.
Advanced features like reusable templates, automation cloning, and visual workflow builders streamline recurring tasks. Reporting becomes easier too—especially when integrated with AgencyAnalytics—allowing agencies to monitor email marketing performance across all accounts in one place.
This reduces the learning curve, accelerates onboarding, and ensures every client benefits from the agency’s refined processes and shared best practices.
AgencyAnalytics connects directly to the most popular email marketing platforms, including Constant Contact, Drip, GoHighLevel, HubSpot, Mailchimp, and more. This makes it easy for agencies to pull all email KPIs into a single dashboard—no spreadsheets or manual exports. It simplifies email marketing performance tracking by automatically importing metrics like opens, click-through rates, automation performance, revenue attribution, and subscriber growth.
Agencies can build white-labeled client reports, schedule automated delivery, and combine email insights with data from SEO, paid search, social media, ecommerce, and CRM platforms. Compared to exporting CSVs or stitching together multiple tools, AgencyAnalytics eliminates reporting bottlenecks and gives clients clear, visual updates they actually understand.
Basic automation typically includes simple sequences like welcome emails, abandoned cart reminders, or time-based drip campaigns.
Advanced automation tools offer deeper personalization through behavior-based triggers, predictive analytics, dynamic content, and multichannel flows across email and SMS.
Platforms like ActiveCampaign, Klaviyo, and Drip provide visual workflow editors, conditional logic, and advanced segmentation that adapts to user behavior in real time.
For agencies managing complex funnel strategies, advanced automation unlocks far more precise targeting and higher conversion rates—especially when combined with website tracking, ecommerce data, and CRM insights.
Agencies supporting ecommerce customers typically need advanced automation, deep ecommerce integrations, and revenue-focused reporting. Tools like Klaviyo, Drip, and Shopify Email excel because they offer dynamic product feeds, cart abandonment flows, predictive analytics, and customer segmentation based on browsing or purchase behavior.
These platforms integrate directly with top ecommerce platforms and support transactional emails, cross-sell recommendations, welcome flows, and SMS automation.
For agencies managing multiple ecommerce brands, choosing an email marketing platform with strong analytics and multi-account support ensures consistent campaign performance and seamless reporting inside AgencyAnalytics.
Great email marketing software helps agencies deliver more targeted campaigns, nurture leads, and monitor audience behavior—resulting in better outcomes for clients. Strong reporting and automation tools make it easy to demonstrate ROI, which improves retention and positions your agency as a strategic partner.
For client acquisition, offering email campaign management or advanced automation as a standalone service can differentiate your agency from competitors. As your agency scales, choosing platforms with enterprise-level features, reliable deliverability, and flexible pricing ensures you can support clients of all sizes while maintaining operational efficiency.
An email marketing performance report gives clients a clear view of how your marketing efforts influence engagement, conversions, and revenue. It typically highlights opens, click-through rates, automation performance, and activity from welcome emails, promotions, and behavioral sequences. Strong reports also show how email supports other channels—whether that’s affiliate marketers, ecommerce flows, or cross-channel SMS automation.
For agencies, choosing reporting platforms with an intuitive interface, clear data visualizations, and a minimal learning curve makes reporting far easier—especially when managing multiple clients. Using tools like AgencyAnalytics, agencies visualize performance alongside website data, sales automation, and broader funnel insights. The result is a report that strengthens client understanding and drives better decisions across every campaign.
