To build a high-quality group of subscribers, you should use things like special freebies (called lead magnets), good sign-up forms, and proper “list hygiene”. In fact, lots of marketers—about 76%—use content like free guides or handy tools to get people to sign up.

For instance, online shops (eCommerce) do really well with emails that remind you about items left in your cart or send you special deals. Meanwhile, software companies (SaaS) focus a lot on emails to help you get started and let you know about new features. Non-profit groups usually send campaigns that use strong stories to encourage donations.

It’s worth noting that, on average, emails for online stores actually bring in about 27% of their total sales, according to Klaviyo. This just goes to show how email changes to fit each industry and why sending emails to other businesses (B2B) is completely different from sending them to individual customers (B2C).

How Your Business Can Benefit from Email Marketing in 2025 and Beyond

You might wonder if email is still worth your time, but here’s the straight answer: it is absolutely essential. Even in 2025, email remains one of the most powerful tools in digital marketing, mostly because of how much money you get back for what you spend.

The Amazing Return on Investment (ROI)

The numbers really speak for themselves. According to Litmus and Omnisend, it shows that for every $1 you put into email marketing, you get about $36 back. That’s a huge return—over 3,600% for many companies! If you’re looking for an efficient way to boost your bottom line, email is still the champion.

Automation Is a Game-Changer

It’s not just about sending emails, it’s about how you send them. If you’re still manually blasting out emails, you’re missing out. Automated email campaign workflows now bring in way more money than one-off, manual sends. 

In fact, according to OptinMonster’s report that using these automated systems can generate 320% more revenue than the traditional approach. This is why investing in the Top email marketing services that offer great automation features is so important for your business.

Unmatched Reach

The sheer size of the audience is what keeps email central to marketing strategies. With over 4.5 billion people worldwide using email in 2025, and that number still growing, you simply can’t ignore a channel that gives you such direct access to such a massive global audience. Below are key advantages you can aim for.

You Can Personalize and Target Your Audience Better

When you use detailed segments (grouping your audience based on specific things), you see a big jump in how engaged people are. Many marketers agree that smart segmentation is one of the most powerful things you can do.

Email Directly Leads to More Sales

On average, companies selling to consumers (B2C) see about a 2.8% conversion rate from email, and companies selling to other businesses (B2B) see around 2.4%. This clearly shows that email is a direct path to making revenue.

It Keeps Your Customers Interested and Loyal

Emails help you stay relevant to your existing customers through regular newsletters, updates, special offers (upsells), and loyalty programs. You stay “top-of-mind.”

When to Use Email Marketing

A 2024 study by Litmus shows that almost 8 out of 10 marketers (79%) consider email one of their top three tools for getting people to notice their brand, buy something, and keep them coming back.

It’s especially valuable when you need to gently guide potential customers toward a purchase, reconnect with those who haven’t engaged in a while, or build strong loyalty through regular communication.

If you’re looking for effective email marketing management services, here are the key ways we use email to get results:

  • Guiding Potential Buyers: Send educational content or a series of messages (called “drip campaigns”) to smoothly move people closer to making a purchase.
  • Keeping Existing Customers: Use personalized updates, special loyalty deals, or useful newsletters to make sure your customers stay interested and engaged.
  • Running Special Sales: Launch limited-time offers, holiday discounts, or promotions tied to specific events.
  • Bringing Back Lost Sales: Simple, well-timed reminders can help you recover a significant number of sales (sometimes 10–15%, based on data from Shopify) that were abandoned in online shopping carts.
  • Winning Back Inactive Users: Target subscribers who haven’t clicked in a while with special offers, quick surveys, or friendly reminders to bring them back into the fold.

To help you begin, here are some topics for those new to this area. These can help you get started with the basics. If you are just starting out, we suggest you check out these subjects. They cover what you need to know.

People check their email constantly. An amazing 99% of consumers look at their email every single day, with many checking it three to five times a day. This habit makes email one of the easiest and most routine ways to get in front of your users.

Absolutely. When you send emails tailored to specific groups (segmented emails), you see much better results. These campaigns can have 30% higher open rates and 50% higher click-through rates than general emails. Basically, customizing your message really pays off.

Setting up your email system to work automatically is hugely rewarding. Studies show that automated campaigns generate 320% more revenue compared to emails you send out manually one by one. This shows why using Marketing automations for better timing and relevance is key to growing your results.

Surprisingly, only about 31% of marketers actually make email a core part of their full marketing plan. Yet, those who do often rely on it heavily for promoting sales or managing the customer lifecycle. This suggests many businesses are missing out on the performance email could be giving them.

According to Nonprofit Tech for Good, nonprofit organizations are heavy email users, with 86% of them relying on it. On average, they send about 62 emails per year to each person on their list, a number that is still growing. Most also use personalization to customize what their subscribers see.

Artificial intelligence (AI) is already a factor. About 34% of email marketers use AI tools—at least occasionally—to help write emails. This includes generating subject lines, drafting content, and figuring out the best time to send. As AI improves, it’s quickly becoming essential for smart, scalable email strategy.

Simply put, your phone is now the main way people check email. More than 46% of all email opens happen right on a smartphone. This means your email design has to look good and work smoothly on mobile. If it doesn’t, you risk losing almost half of your potential readers before they even see what you wrote!

Research gives us a pretty clear hint here: the best time to catch people’s attention is typically on Tuesday mornings, specifically between 9 a.m. and 11 a.m. Although your own audience might be a little different, this data shows why it’s so important to test your send times.

Using a recipient’s name or adding a specific, personal detail in the subject line isn’t just a nice touch—it’s a smart strategy. A good email marketing platform makes it easy to add these personal details. Doing this boosts your open rates by about 26% on average. It’s how you cut through a busy inbox.

Social media is excellent for getting the word out, but when it comes to actually making a sale, email is the winner. Studies show that email is 40x more effective than Facebook and Twitter combined at bringing in new customers. This is why email is still one of the most reliable tools for getting a return on your digital marketing investment.
