Email automation is the process of sending marketing and sales emails to subscribers automatically based on their actions or lack thereof. It involves setting predefined rules to determine which emails should be sent, when to send them, and what personalized information to include. This enables marketing and sales teams to deliver customized messages to potential customers at the perfect moment while reducing their workload.

For instance, say a company offers a 10 percent discount to new website visitors who subscribe to the company’s email list. Traditionally, the team would manually enter each new subscriber's name and send an email with the promo code.

Email automation software eliminates the need for manual personalization and sending. It ensures that marketing, sales, and prospecting emails are automatically triggered and delivered to the right people at the right time. As a result, conversion rates increase, and the team's workflow improves. Adopting email automation gives businesses a competitive advantage over competitors who still rely on manual methods.

Email automation is built into many platforms, but there are a few that offer unique features. Here are our top email automation platform picks for 2025.

When you’re shopping for the best email automation software for your business, make sure you’re choosing one with the features you need right now. Here are six features many businesses prioritize in their search.

Sales engagement tools

Automation can help your team save time, but it won't provide its maximum value if it doesn’t also improve your sales success. Along with automating email sends, your software should also support sales engagement with:

• Customer profiles: Personalize the information in your emails by pulling information from customer profiles and buyer personas.
  
• Lead scoring: Qualify sales leads based on the potential value they provide so you know how to prioritize outreach.
  
• CRM integration: Sync email interactions, track customer behavior, and create a unified view of customer data.
  
• Product recommendations: Suggest new products or services to customers using insights gathered from their buying history and personal characteristics.

Email automation doesn’t need to treat marketing and sales initiatives as either/or goals. When software has the right tools, it can help both departments achieve greater success.

Sequences

An email sequence sends messages to a customer at predefined intervals to engage prospects and nurture leads. Each sequence can automatically populate personal information in emails so that they feel like a human sent them.

A good email automation tool can recognize if a person has responded to an email and adjust its messages accordingly. For example, if a customer responds to the first email, but there are still three follow-up emails in the sequence, the software will cancel the remaining emails so that the sales team can answer the customer.

Bulk outreach

One of the best ways email automation improves productivity is by sending bulk outreach emails to leads. Rather than having an employee personalize and send individual messages, the software can send thousands of emails on its own.

For example, welcome emails are a great way to engage new subscribers, but if an employee were to do it manually, it would be a time-consuming process. Bulk outreach can instantly send an automated welcome email to every new subscriber, auto-populating names and providing them with the information they need to get started with your company.

Sales triggers

Sales triggers automate portions of your reps’ workflows. Your automation software should allow you to set up conditions so the trigger will carry out your desired action when a specific event takes place.

For example, when a customer makes a purchase, a receipt can be sent to their inbox automatically. More advanced sales triggers are also possible, like updating team roles when changes to a customer account occur.

Smart lists and templates

Having organized lists of contacts makes it easier to reach out with targeted emails, increasing your chances of gaining successful lead conversions. If your email automation features can’t segment customers into smart lists based on their personal characteristics or purchasing habits, you’ll essentially spam them with irrelevant information.

Having smart list functionality also means you can create email templates that target each customer segment. Your automation platform should provide pre-built templates that make it easy to start sending effective emails immediately. The software should also allow you to customize templates to match your brand identity and support specific sales initiatives.

Email campaign support

Monitoring and actively managing your marketing campaigns is important to their success. Whichever email automation software you choose should either provide or integrate with tools that make this process easy for your team. Be on the lookout for features like:

• A/B testing: Compare the performance of different versions of the same emails.
• Engagement tracking: Measure open, click, and response rates to emails.
• Lead generation: Source contact information for companies and individual prospects.

Since email automation platforms specialize in different things, it’s unlikely that you’ll find one service that can support all email campaign initiatives on its own. If a platform you’re interested in lacks a feature you want, like advanced email analytics, research if it has integrations that can fill the void.

Unified platform

Unifying sales and customer service platforms enhances email automation efforts by creating a seamless flow of information between the two departments. This integration ensures that both teams have access to the same customer data, allowing for more personalized and timely email communications.

For instance, when a customer makes a purchase, the sales platform can instantly notify the customer service platform, triggering an automated thank-you email or a follow-up survey. Similarly, if a customer raises a concern via the customer service platform, the sales team can be alerted to potentially adjust their approach or offer tailored solutions in their subsequent communications.

Mobile app

Having a mobile app significantly bolsters email automation by providing real-time access and responsiveness to user interactions. With a mobile app, businesses can track user behavior and preferences on the go, enabling them to send timely and contextually relevant automated emails.

If a user browses a product within the app but doesn't make a purchase, the system can trigger a targeted promotional email to nudge the user toward conversion. Additionally, push notifications from the app can complement email campaigns, ensuring that users receive important messages even if they miss an email. The combined effort of mobile apps and email automation ensures a consistent and personalized user experience.

Email automation is a powerful tool that can help businesses save time, increase efficiency, and improve the effectiveness of their email marketing campaigns. Here are some specific benefits companies can gain from using this technology.

Higher sales

Segmenting your email list means you can group your contacts based on factors like industry, company size, or stage in the lead funnel. You can then send targeted emails that are more likely to be read, which can lead to more sales.

Additionally, the software helps you track and measure the results of your email marketing campaigns. You can see how many emails were sent, how many were opened, how many clicks were generated, and so on. This information can help measure the effectiveness of your campaigns and make improvements to your approach.

Greater team productivity

Since email automation software can handle welcome messages, marketing campaigns, and email responses, your team can spend more energy on other duties. All your team needs to do is set up the triggers to send emails based on certain criteria, such as when a contact abandons their cart at checkout.

Better customer experience

Email automation software can help businesses to personalize their emails at scale, which means that they can address each recipient by name, use relevant keywords, and tailor the message to their specific needs. The software also helps you create a more personalized and engaging customer experience by sending relevant and timely emails to customers. This can help to build customer loyalty and trust over time.

Higher employee satisfaction

Any time a business can make daily life easier for its employees, company morale will see positive improvements. Taking away many of the repetitive email tasks from your employees' responsibilities also removes unnecessary stressors. Employees’ workloads are streamlined, and their mental bandwidths will be reserved for more crucial tasks.

Choosing the right email automation software can feel like a daunting task, but properly researching your options will set you up for success down the line. Here are four important questions to answer to help guide you to the best option for your business needs.

What is your use case?

As mentioned earlier, email automation software has a range of sales, marketing, and customer service applications. Some software only supports one use case, while others might do a little of everything. Consider which departmental efforts are a priority and look for a software provider that provides the necessary features.

If you focus on assisting the sales team, you might benefit the most from automation software that leans into sales engagement tools. Marketers, on the other hand, will likely need marketing automation tools that will help them manage campaigns.

What is the time to value?

A product or service’s time to value refers to how long it takes to receive a positive return on your investment. Automation software with prebuilt email templates and workflows will have a shorter time to value than one requiring you to build them yourself. You’ll also want to read reviews regarding the system’s ease of use. If it takes your team weeks to learn how to automate email sequences, it’ll prolong your time to value.

Can it integrate with your other platforms?

Even simple functions like email automation can be severely hindered if they can’t connect to your other systems. Automation is supposed to save time, but that won’t happen if employees have to manually enter customer information into the system from your CRM. Make sure that your software of choice integrates with the other platforms your employees use so that they can get the most value from it.

What is the total cost of ownership?

The software included in this roundup are good examples of the variety of pricing options in the market. Some software charges per user, while others charge based on email volume. While the sticker price of one might seem like a better deal at first, as your email volume grows, you could spend more on the service as a result. Look at how many emails you currently send per day and/or month and compare how that might affect your monthly rates.

The following email automation examples illustrate the importance of speed, ease, and timing in your email flow. With each example, we’ll explain the sales email scenario and triggers that help achieve desired results.

Example #1: The welcome email

Say an e-commerce business launches an initiative that offers new website visitors a 10 percent discount when they subscribe to the email list. After two weeks, the subscriber list has grown by 200 emails. Unfortunately, very few subscribers opened the email and clicked through to the website, and only one took advantage of the discount. To add to the frustration, the business owner realizes there are now too many contacts to manage with spreadsheets alone.

The owner decides to sign up for a free CRM trial, which includes contact management and the ability to automate emails. Using the new platform, they set up a welcome automation trigger. The trigger occurs when a new website visitor submits their information in exchange for the 10 percent discount. The owner also adds a personalization tag to the welcome email so the subscriber’s name automatically appears in the salutation.

Triggered emails have 32 percent higher open rates and 73 percent higher click-through rates than routine emails. So, even without factoring in changes to the sales email subject line or messaging, the owner has already theoretically improved open and click-through rates by automating the process.

Example #2: The follow-up email

Sales follow-up emails are a vital tool for rekindling interest in leads who need a little nudge to take the next step. For this example, let’s imagine a larger business-to-business (B2B) setting. Our theoretical business sells industrial machinery. The sales process is very complex, so the sales reps have little time for personalizing and sending emails.

At a trade show, a salesperson used their CRM app to collect the contact details of their new leads. The salesperson promised to send more information about the specific products that will help the leads solve their problems. Before the salesperson returns to the office, the email automation tool has already sent personalized follow-up emails.

But it’s a busy time of year, and the first round of emails doesn’t get many bites. The company decides to set up a chain of five follow-up emails scheduled to send once a week over five weeks. If the lead doesn’t take any action, their contact details are put aside until a new round of outreach begins.

In the third week, a lead decides to schedule a meeting with the sales rep. Using the link in the automated email, they click through to a scheduler and select an available time slot in the sales rep’s schedule. This sets off another trigger that stops the chain of email follow-ups.

Example #3: CSAT surveys

Customer satisfaction (CSAT) surveys help businesses gauge how well they’re meeting customer needs. Say a smart home device retailer wants to use email automation software to streamline the CSAT survey process.

The retailer sets up a trigger for the software to recognize when a purchase is entered into the system. The trigger automatically schedules a CSAT survey to go out to each customer. Included in the email are the details of the purchase that were captured in the business’s CRM, such as the customer’s name.

As responses are received, the software categorizes the feedback and highlights trends that need attention. Negative feedback triggers an immediate alert to the customer service team so they can follow up. A final automated thank you email is sent to close the feedback loop.

Look to the following common questions for additional help improving the email productivity of your company.
