Why email marketing still matters in 2025
A well-targeted email will outperform social media posts and paid ads most of the time. Particularly in markets like online education and digital products, where intimate communications matter more than visibility.
But even beyond conversions, email marketing is not the same as a few years ago.
Automation has become smarter. AI now assists in crafting personalized content at scale. And segmentation strategies have grown increasingly granular. Modern email newsletter software sending messages en masse anymore. It builds relationships, automates follow-ups, and delivers the right message to the right person at the perfect time.
Today, email marketing helps you stay top-of-mind, build trust, and guide leads through a thoughtfully designed funnel. From welcome sequences to course launch campaigns, email ensures your message cuts through the noise, which is something social media algorithms can’t guarantee.
Key features to look for in an email marketing tool
Choosing the right email newsletter software is essential for scaling your online course promotion. Whether you’re just starting out or running multiple funnels, here are the key features that make the difference:
Intuitive automation and workflow builders
Look for tools that offer intuitive drag-and-drop automation builders. This way, you’ll be able to create sequences for onboarding, nurturing, and re-engagement without needing technical skills.
Personalization and segmentation features
The option to send personalized content based on behavior, interests, or stage in the funnel is a must-have. Segmentation ensures your emails are relevant, which leads to higher open rates and conversions.
Analytics and A/B testing
Data-driven decisions are essential when you want to scale and evolve as an online course creator. Choose a platform that manages your data and provides clear analytics on open rates, click-through rates, and conversions, along with A/B testing tools to refine your messaging over time.
Scalability and ease of use
Your email marketing tool should grow with you. It needs to be easy to learn, but powerful enough to offer more sophisticated tools and handle more complex campaigns as your audience expands.
Cost-effectiveness and transparent pricing
Finally, pricing matters. Many email newsletter software platforms offer generous free plans or low-cost options tailored for small businesses, which is perfect for creators just getting started.
The right email marketing platform empowers you to do more with less effort, freeing up your time.

How Knorish complements email marketing tools
Email marketing and course platforms serve two distinct but equally vital roles: nurturing interest and converting it into revenue. Think of it like this: email is for lead nurturing, while Knorish is for lead conversion.
Imagine you’re using one of the best email marketing platforms like Moosend or Mailchimp to capture leads. Using landing pages, pop-ups, and embedded forms, you can offer a compelling lead magnet (like a free guide, checklist, or mini course) in exchange for an email address.
As soon as someone signs up, an automation flow kicks in, sending a welcome sequence, delivering the lead magnet, and nurturing that lead with a series of personalized, behavior-based emails.
Now that you’ve built trust and interest, it’s time to convert that lead into a paying customer. This is where Knorish comes in. Once your lead clicks through from the final email in your sequence, they land on a beautifully branded Knorish course page. From there, you can automatically enroll them into a paid course, offer an upsell, or deliver exclusive gated content, all hosted and delivered through your Knorish platform.
This seamless integration between email marketing platforms and Knorish allows you to guide leads from first interaction to final conversion without adding manual steps. The result? A fully automated system that builds your list, nurtures your audience, and builds the perfect sales funnel for your digital products or online courses.
Grow your online courses with email marketing
Choosing the right email marketing tool can make or break your digital business. Whether you’re just starting out or scaling an established online course brand, the right platform will help you capture leads, build trust, and drive consistent sales.
But email alone isn’t enough. To truly convert your audience into paying customers, you need a system that connects marketing with delivery.
That’s where the combination of a powerful email newsletter software with a platform like Knorish becomes so effective. Email handles the nurturing part of building relationships, educating your audience, and guiding them through your funnel. Knorish takes it from there, helping you deliver paid content, enroll students, and create an experience that reflects your brand. When these tools work together you’re building a sustainable, automated ecosystem that turns knowledge into income.
