Let’s dive in.

What is email marketing software?

An email marketing tool is any software or platform that helps you create, send, and track email campaigns.

It simplifies the process of designing emails, managing subscriber lists, analyzing campaign performance, etc. So, it's a great way for business owners like you to promote products, services, or information to a targeted audience via email.

Email platforms often have well-designed email templates and analytics dashboards that help focus on specific key metrics like open rates and click-through rates.

They should also have email automation, segmentation, and email personalization features.

What to look for in an email marketing tool

Choosing the right email marketing tool will depend on the specific needs of your business, the size of your email list, your budget, and the features you need for your email marketing campaigns.

Here are the core criteria you can look at when evaluating email marketing tools:

• Ease of use: Your email marketing software should be user-friendly with an intuitive interface. Time spent struggling with a tool is time taken away from core business activities.
• Cost: Consider both the immediate costs and potential long-term costs as your subscriber list or feature needs grow.
• Scalability: Make sure the software can cater to your needs as your business grows. Frequent platform switches can be disruptive and costly.
• Integrations: Check for compatibility with other tools you use, like CRM systems, eCommerce platforms, and social media integrations. This can help to streamline workflows, maintain data consistency, and lead to more upsells and faster deals.
• Segmentation features: Robust segmentation capabilities are essential for targeting different industries, company sizes, or stages in the buying cycle.
• Personalization and automation: Personalized content can significantly enhance engagement. Look for tools that allow automated email workflows based on user behaviors or specified triggers.
• Analytics and reporting: Comprehensive insights into open rates, click-through rates, bounce rates, and more can guide strategy and improve campaigns over time.
• Deliverability: Make sure the tool has a good reputation for getting emails into recipients' inboxes and not spam folders.
• Templates and design: Access to well-designed, mobile-responsive templates can save time and ensure your emails look professional.
• Customer support and community: A responsive support team and a vibrant user community can be invaluable, especially when you run into challenges or need tips.

Email platforms have a wide range of features and the challenge is knowing which feature you need the most. Let’s go into more detail on the each of the main features your email marketing tool should have.

Drag-and-drop user interface

It's not 2005 anymore. Every email marketing platform you use has to have a drag-and-drop editor. I remember when Mailchimp finally launched theirs a few years ago.



Segmentation

Not every person on your list should receive the same email. Your email marketing campaigns should be sent to specific customer segments. Most email marketing tools have advanced segmentation features that let you segment your audience based on their purchase history, interests, demographics, and their behavior on the site.



Personalization

Personalization goes beyond putting the customer's first name in the body of the email. Customers want to have a truly personalized experience with the brand, regardless of the marketing channel they use to interact on. So, advanced personalization includes:

• Dynamically displaying the specific products the user browsed or added to their shopping cart.
• Customizing the loyalty or rewards program information for each subscriber
• Changing the images and the copy of the email based on user data

Automation

Marketing email automation is one of the most important and powerful features you should look for in an email tool. Automation means setting up email campaigns and email marketing flows that go out automatically based on customer behavior. Some email marketing tools can let you automate entire customer journeys using multiple channels like email, SMS, chatbots, and push notifications.



A/B Testing

A/B testing is one of the most important features in any email marketing campaign. The best way to improve your conversion rates is to test your subject lines, preview text, and the design and body of your emails. Studies show that 58% of successful email marketing programs are more likely to A/B test their emails at least once a year.

SMS marketing

One of the best ways to boost your email marketing efforts is to connect new channels and the most powerful one is SMS. Just look at these stats:

• The average click-through rates of text messages are 19.3%
• 34% of people read their text messages within five minutes of receiving them
• 96% of marketers using text messages said they helped them drive revenue.

You can significantly boost your engagement and email revenue by combining emails with text messages in your customer journeys.

Chatbots

Chatbots are another great channel you should combine with email marketing. Some (not all) email tools have integrations with chat tools. For B2B, you could combine your email campaigns with targeted chat messages on your site chat.

Ecommerce brands should combine email campaigns with messages on Facebook Messenger, WhatsApp, and other channels their users may be using. It works really well with abandoned cart emails and retargeting campaigns.

Reports and analytics

Every good email marketer lives and breathes their analytics reports. They would actually bury their hand in the sand for a week if they could and just read reports.

Analyzing everyone one of your email campaigns is super crucial for the success of the entire channel. You should check the unsubscribe rate of each campaign to make sure that you are not sending too many emails and the deliverability rates of your emails to make sure they're not landing in the spam folders (which an email deliverability consultant can help you with).

You should check your site bounce rate to make sure that your email traffic is not clicking on an email and then leaving (what's called message match).

Best email marketing tools to use in 2025

Here are the best email tools to use, in no particular order. We tried to be as unbiased as possible, enjoy!

Mailchimp



Mailchimp has been one of the most popular email marketing tools for a long time because it was one of the only tools that had a free plan. It's perfect for B2B and small businesses, although it doesn't have some of the advanced features of tools like Constant Contact or Campaign Monitor.

One challenge that Mailchimp experts seek to alleviate is that it’s not built for eCommerce. It doesn't have the core features you would need to use like automation, and eCommerce tracking, and it makes it really difficult to set up abandonment email flows. It also lacks some of the built-in integrations you would need for an eCommerce brand.

Overall, it's a great solution for email marketers that are starting out, or just beginning to build their email strategy.

Key features:

• Customer journey builder
• Sent time optimization
• Behavioral targeting

It also has web push notifications so if you're planning to include other channels in your email marketing strategy then this is the tool for you. The drawback is it doesn't have SMS, but you could integrate an external tool like Burst SMS and get those same features.

Constant Contact



Constant Contact is another popular email marketing service but it stands out from the pack. It's an email marketing tool by day and a social media scheduler by night.

It can help you create, schedule, and analyze the performance of your social media posts. It also has an automated Google Ads tool that lets you improve your targeting and create lookalike audiences.

It's interesting to note that Constant Contact recently developed a robust CRM platform that helps you with lead scoring, opportunity management, sales automation, tracking, and analysis.

One feature that I've never seen anywhere else is Campaign Monitor's Link Review tool. It checks all the links in your email and then alerts you if one of them are broken. Other than that, it has the same feature as Klaviyo but it's way cheaper (closer to Constant Contact's pricing).

Why does email marketing matter?

Email marketing has one of the highest returns on investment of any marketing channel. Studies show that for every $1 you spend on email marketing you could get $36 in revenue. Email marketing takes all of your leads from ads, social media, organic search, etc., and converts them to paying customers.

What does email marketing software cost?

On average, a mid-size business can expect to spend between $0-$1000 per month on email marketing if they manage it themselves. It depends on the platform and the number of contacts they have. If they work with an agency it could cost them $300-$500.

Does CRM software include email marketing?

Most CRM software has basic email marketing features but not the entire suite of email marketing automation, flow creation, and analytics and reporting that email tools offer. A good tool combines customer relationship management (CRM) software and email marketing software. So it collects data on your contacts and helps you send more relevant and effective communications.

How to choose the best email marketing software platform

Ok, so you have a giant list of email service providers. Which one do you pick? Here is a step-by-step process to help you choose the right tool.

Pick your goals

First, determine what type of emails you want to send. Will you be sending transactional emails? Promotional emails? A weekly newsletter? Once you know what type of marketing emails you’ll be sending then you can pick out the features you need.

Oh, and by the way, if you want to send engaging Thank You emails that build relationships, take a look at our list of quick and effective Thank You email examples!

Pick must-have features

What are the basic features you need to send out your email campaigns? Are you looking for an email provider that has built-in email automation tools? Are you looking to automate a series of emails? Would you be designing emails from scratch or do you need to have a library of templates to use?

Match features to goals

Now it’s time to match the features of your email tool to your goals. Compare the features and see if they match your goals. How many email addresses would you start with? Does it have a month-to-month plan? What’s the actual price that you are willing to pay?

Create a plan

Make an outline of the exact features that you’ll be using and how you will want to execute your email marketing plan.

Start with the free plan

Don’t go for the premium plans right away, especially if you’re sending less than 1,000 emails per month. Start with the free plan and see if you like the interface, if the automation features are easy to use, and if the tool brings you value. You can always upgrade it once you like it.
