This blog article will guide you through these elements so you can feel confident in your hiring decision.
What Makes a Top 10 Email Marketing Agency “Good”
Just because an agency says they’re the best doesn’t mean it’s the perfect fit for you. But what makes a good agency? Here are nine key attributes of a top 10 email marketing agency.
#1 Proven Track Record
A top 10 email marketing agency doesn’t just claim to be the best—they can easily prove it. A strong portfolio and case studies showing real results across various industries should be showcased on their website, in marketing materials, and in a sales pitch. Don’t just take their word for it. You can even ask for references and connect with current clients for additional validation.
#2 Strategic Expertise
An experienced agency does more than just send email campaigns. They start by building comprehensive marketing strategies. These may include everything from cold email outreach and list segmentation to customer journey mapping and automation. By carefully crafting a bigger digital marketing picture, your business can take advantage of services that work together—and grow your business.
#3 Custom Solutions
Top 10 email marketing agencies don’t offer a one-size-fits-all approach. Instead, they become a true partner, learning your business inside and out. Using their strategic expertise, an email marketing agency should take into account your specific business goals—then create a solution tailored to deliver a solid ROI for your unique business.
#4 Data-Driven Approach
A good agency knows that continuous improvement is key to delivering results. By using analytics to constantly optimize campaigns, test various components, and analyze customer behavior, an agency can create more relevant, efficient, and valuable marketing campaigns.
#5 Creative Excellence
Top 10 email marketing agencies produce compelling copy, design, and messaging that reflect your brand and engage your audience. Let’s break it down.
- Compelling Copy. Good copy can make or break your chance to win over a prospective customer, build trust, and make a sale. The important thing is that you use your copy to make a meaningful connection with your audience. And every email is an opportunity to do this.
- Expert Design. A visually-appealing design will make your email stand out in a cluttered inbox. Unfortunately, it’s all too often that brands use cookie-cutter email templates… and customers can tell.
- On-Brand Messaging. Does your email sound like Any Company, USA? Or does it look, feel, and read like your unique brand? By using a consistent brand voice and style, every campaign should be an extension of your company.
#6 Compliance Knowledge
If you’re sending emails to customers, you must comply with email regulations like GDPR and CAN-SPAM. And if your email agency is sending on your behalf, they must be equipped with compliance knowledge. Why? It protects your business, ensures audience trust, and keeps your emails from landing in spam folders.
#7 Advanced Tools & Tech
Top 10 email marketing agencies are experts at various email platforms and can help you identify which will serve your business best. Platforms like Klaviyo, Mailchimp, and ActiveCampaign each have their own strengths, weaknesses, and price points—and not all will service your business the same.
Additionally, your email agency should know how to integrate with various CRMs and ecommerce platforms. This is especially important because platform integrations allow you to easily access data for list segmentation, personalize your emails with dynamic content, and trigger automated email campaigns tailored to your customers. It’s a data gold mine!
#8 Strong Communication
An email marketing agency that regularly communicates with your customers should be able to seamlessly keep the lines of communication open with your business too. The agency should offer transparency, clear reporting, and consistent updates so you’re always in the loop.
#9 Scalability
Whether your business is currently in start-up mode and in need of a smaller email marketing plan—or if you have an enterprise-level business in need of something more robust—a top 10 email marketing agency should be able to deliver. The important piece is to partner with an agency that offers scalability. As your company grows and changes over time, your email marketing partner can evolve with you… while still delivering a strong ROI.
As you can see, not all email marketing agencies are created equal. Just because one claims to be the best doesn’t mean it’s the right fit for your business.
The top email marketing agencies stand out by offering much more than canned email blasts. They bring a proven track record, strategic expertise, and custom solutions tailored to your goals. Furthermore, they rely on data to continuously improve results and deliver standout creatives that reflect your brand. A top-tier agency also ensures compliance, uses advanced tools and platform integrations, communicates clearly, and can scale with your business as it grows.
In short, the best agency isn’t just a vendor—it’s a strategic partner.
Email Marketing Services You Want & Need
Equally as important as these key attributes are good offerings. A top 10 email marketing agency should also provide a multitude of services that meet your business’s current and future needs. From creating a strategy and building an email list from scratch to driving prospective customers to your website, it’s more than just email.
Here are several of the vital services a top 10 email marketing agency should offer.
Strategy Development
As previously mentioned, a good agency leads with a custom strategy to meet your business’s unique goals. Strategy development includes the following at a minimum:
- Audience research and creation of an avatar or ideal customer
- Email marketing roadmap that’s aligned with business goals
- Campaign planning and calendar development
Email Campaign Management
An agency should manage your campaign execution from beginning to end, including content creation, design, and coding. They should schedule campaigns to launch at optimal times and ensure successful delivery. Plus, A/B testing should be incorporated regularly to optimize subject lines, calls to action (CTAs), layouts, send days and times, and other variables.
Lead Generation
Your top 10 email marketing agency can create the most beautiful campaigns. But without a consistently-growing email list, you’ll have no one to send them to. There are many strategies for lead generation with varying recommendations based on your business:
- Cold Outreach. Use this email strategy to reach thousands of potential customers, responding only to hot leads.
- Lead Catchers. These tools, such as popups and static join forms, are coded into your website. By offering something of value (a giveaway or newsletter), you’ll get a visitor’s first name and email address.
- Staff Forms. If your business has retail locations, use a staff form to manually collect contact information from patrons who enter the store.
List Management
Once you have a solid email list, it’s important to manage it. This includes capturing additional details, such as behavior, demographics, and purchase history, so you have the ability to segment your audience and send more targeted messages.
List hygiene is another facet of list management. It’s the process of cleaning out old and unengaged contacts to improve deliverability and sender reputation. This ultimately results in higher engagement rates and keeps you off email blacklists.
Automation Campaigns
Known as the powerhouse of email marketing, email automation is a key service for a top 10 email marketing agency. It’s also referred to as a sales funnel or drip campaign. Whatever you call it, make sure to hire an agency who can employ various automation tools for success. Types of automations include the following:
- Welcome Series—Introduce your business to new audience members.
- Abandoned Cart Flows—Remind customers they’ve left something in their online carts, and potentially offer an incentive to return and complete the purchase.
- Expiration Reminders—Nudge consumers to repurchase or replace a product before it expires.
- Win-Back Emails—Reach out to customers who haven’t purchased or engaged with your brand in a while.
- Product or Service Review Requests—Contact customers after a purchase and encourage them to leave a review.
Technical Setup & Integration
A top-tier agency has an integration specialist on staff who can help with a variety of things:
- ESP (email service provider) setup and management through Klaviyo, Mailchimp, ActiveCampaign, and others
- CRM and ecommerce platform integrations like Shopify, Salesforce, and HubSpot, for example
- Spam testing and deliverability optimization
They can handle all the technical details while the rest of the team makes the most of your strategy, goals, and messaging.
SEO Blog Articles
Is your business the first thing a customer sees when they search for services or products you offer? It should be—and SEO marketing can help. By creating a strong digital presence for your business, you’ll attract more potential customers to your website. And once they arrive, you can capture their contact information and start to build a relationship.
An SEO service will help identify keywords and opportunities, as well as create and write content to increase traffic to your site. As an added bonus, it’s less expensive than pay-per-click (PPC) advertising.
Bonus Services
Your top 10 email marketing agency should always be building their portfolio of services to meet your needs. Here are some bonus services to consider:
- Tradeshow marketing
- Landing page creation
- Webmaster
- Google Ads
- Email marketing audit
