The 7 Best Email Marketing Platforms for Agencies (And Clients)

By now, it's abundantly clear that email is not only one of the most popular marketing channels but also one that is worth investing in (no matter what industry you work in).

Here are a few statistics for you.

Clearly the decision to invest in an email marketing platform, and subsequently develop a strong email marketing strategy, is worthwhile if you're looking to drive leads and revenue. You've heard the age-old sayings about email. For every $1 spent on email marketing, $36 is made in return. That's a 3600% ROI and a very overused stat but one you can't really argue with.

Choosing a platform can be somewhat daunting. No matter which platform you go with, it's essential to first assess your agency's baseline, how fast you're growing, the needs of your clients, and the goals you hope to achieve with an email marketing tool. After all, this is the tool that will help you save time, automate processes, and increase client retention.

With a lot of options to choose from, we've put together a list of the best email marketing platforms for agencies and broke each down to their pros, cons, and what each will cost.

First off, email marketing is like that trusty Swiss Army knife in your digital marketing toolkit. It's versatile, reliable, and incredibly effective. Here’s the lowdown on why it’s worth the investment:

• Direct line to your audience: Email marketing gives you a direct line to your audience's inbox. Unlike social media, where algorithms decide who sees your posts, emails land straight into your subscribers’ inboxes. It’s like having a VIP pass to your customers' attention.
• High ROI: We touched on this above but the return on investment for email marketing is massive. For every dollar spent, you can expect an average return of $36. That’s a mind-blowing ROI compared to other channels. Why? Because you're reaching people who’ve already shown interest in what you offer.
• Personalization: With email marketing, you can get super personal. Segmentation and personalized content mean you can tailor your messages to different audience segments, making your communication more relevant and engaging. It’s like sending a handwritten note instead of a generic flyer.
• Measurable results: One of the best parts of email marketing is that you can track everything. Open rates, click-through rates, conversion rates—you name it, you can measure it. This means you can constantly refine your strategy based on what’s working and what’s not.
• Builds relationships: Emails aren’t just about selling; they’re about building relationships. Consistent, valuable emails help nurture leads and maintain connections with your audience. Over time, this builds trust and loyalty, which are gold for any business.
• Cost-effective: Compared to other marketing channels, email marketing is relatively cheap. There are no big ad buys or production costs. With a solid strategy and a bit of creativity, you can achieve great results without breaking the bank.
• Scalable: Whether you’re a small agency or a big player, email marketing scales with your business. You can start small and ramp up your efforts as you grow. Plus, there are tons of automation tools out there to help you manage email marketing campaigns efficiently.
• Great for content distribution: If you’re creating awesome content (blogs, videos, case studies), email is a fantastic way to distribute it. You can drive traffic to your website and keep your audience engaged with your latest and greatest.

Email marketing is a no-brainer for agencies. It’s powerful, cost-effective, and builds lasting relationships with your audience. So, if you haven’t already, it’s time to invest. Your future self (and your bottom line) will thank you.

Let's talk about what you should look out for when hunting for the perfect email marketing platform for your agency. There's a lot to consider to make sure it's a good fit. Here’s a handy checklist to guide you:

• Ease of use: Let’s be real—you don’t want to spend hours figuring out how to send a simple email. Look for a platform that’s user-friendly with a clean, intuitive interface. Drag-and-drop builders are a big plus here.
• Automation capabilities: You want a platform that can handle automated sequences like welcome emails, drip campaigns, and follow-ups without you having to babysit the process. It’s all about working smarter, not harder.
• Segmentation and personalization: Make sure the platform allows for easy segmentation and personalization. You want to be able to tailor your messages to different audience groups to make them as relevant as possible.
• Integration options: Your email marketing platform should play nicely with the other tools in your tech stack. Whether it’s your CRM, e-commerce platform, or social media tools, seamless integration is key to keeping your workflow smooth.
• Analytics and reporting: Look for a platform that provides robust analytics and reporting. You want detailed insights into open rates, click-through rates, conversions, and more so you can constantly refine and improve your strategy.
• Deliverability rates: All the fancy features in the world won’t matter if your emails aren’t making it to inboxes. Research the platform’s deliverability rates to ensure your emails will actually reach your audience.

At the end of the day, it’s all about finding the right balance between functionality and ease of use.
