Best email parsers

Best email parser for your team in 2024

18 min read

It’s no secret that email is the most widely used channel for business communication today — the average person receives 121 messages in their inbox daily. What might be more surprising is how much valuable customer data is scattered throughout email. Invoices, shipping confirmations, contact information, you name it. This data found in email bodies, subject lines, and attachments is powerful when trying to understand customer behaviors and preferences, improve your product, and, ultimately, drive positive business outcomes. 

Extracting usable insights from email inboxes is not easy. Email data comes in various formats, including plain text, HTML, and attachments like PDFs or images. Identifying useful information from each email and manually moving it to a CRM or automation tool is tedious and unrealistic. This is especially true when dealing with large volumes of emails. However, the best email parsers eliminate the challenging, manual labor. They handle the nitty-gritty of data extraction and filtering and organizing it into actionable, first-party data.

With a handful of email parsers on the market, each catering to specific needs, choosing the right one for your business can be overwhelming. Today, we’ll explore some of the best email parsers available to help you and your team find the best fit.

What is an email parser?

An email parser is AI-powered software that extracts data from emails. Think of it as a digital mail sorter — it sifts through your inbox and can be configured to pull specific data from the subject line, email bodies, or attachments. On top of that, email parsers act as a bridge between your emails and workflow automation tools. APIs power these integrations, enabling the email parser and business applications to communicate instructions, exchange data, and process the information from incoming emails. 

Email parsers deal with two primary data types: structured and unstructured. Think of structured data as what you’d find in an Excel file. It’s labeled in columns and rows, and the data is defined. Unstructured data, on the other hand, is what you’d find in a Word document. There is no format or labels. Email parsers can identify and make sense of both types of data.

Email parser features

An email parser does more than collect data. It combines disparate information so businesses can make informed decisions about their customers, products, and strategies. Let’s take a closer look at the features of the best email parsing tools: 

Data extraction

Email parsers read and extract specific data from a user’s inbox. The information a parser collects is determined by its configuration, which varies based on the needs of its user.

Examples of data that email parsers extract:

  • Contents of the body of the email
  • Email metadata
  • Subject lines
  • Send dates/times
  • Open dates/times
  • Reply dates/times
  • Attachments
  • Signature data
  • Links/hyperlinks

Automation and workflow integration

Now that you’ve extracted the data from email, where does it go? Email parsers can integrate with several applications, such as CRMs, e-commerce platforms, fintech, etc.  Here are some examples of workflows you can automate with email parsers:

  • Sales & lead generation: Email parsers can be powerful tools for sales teams. They extract crucial data from incoming emails and connect them with workflow automation tools. As a result, sales teams can streamline prospecting for high-value opportunities and free up time to focus on building relationships and closing deals.
  • Customer support: With email parsers, customer service teams can quickly identify and organize support emails and route them to the appropriate team. This saves time for the team and speeds up the customer response time.
  • Administrative tasks: Invoices, reports, and account reconciliations are often emailed. Email parsers eliminate the need for manual input, saving valuable time and resources while ensuring the accuracy of these processes. 

Customization and scalability

Every business is unique. Whether developing software, selling homes, or managing customer orders, email parsers can be tailored to meet your needs. Companies can configure the parser with custom rules and requirements, defining the data to extract. This allows them to fit different business processes and handle emails from other sources in varying formats without additional resources.

As a business grows, so does its email volume, complexity, and overall needs. Email parsers are adept at large-volume processing and handling complexity and can seamlessly grow with the business’s evolving needs without the typical tradeoffs of delays or breakdowns.

Benefits of email parsers

Email parsing significantly streamlines business processes and provides customer intelligence to drive business outcomes. Let’s examine these benefits in more detail.

Automate business processes

Email parsers accelerate business operations by automating data extraction and integration into workflow applications — from capturing data from qualified leads to processing online forms and invoices. They eliminate the need for manual data entry, help ensure data accuracy, and free up time for other tasks.

Real-time customer intelligence 

While web analytics or third-party research can paint a picture of your customer’s behavior, the most accurate, real-time insights lie in first-party data like email. Email parsers extract valuable data from a business’s inbox to provide context-rich insights. They can then be utilized for segmentation, campaign, and adoption strategies. This is essential to creating personalized customer journeys and, as a result, allows businesses to improve their decision-making and customer experience. 

Improve business outcomes

Email parsers extract valuable data for businesses to understand their customers’ behavior and intent, which enables them to better engage, sell, and retain users. Actions such as order tracking, real-time shipping updates, offers and promotions, and expense management all affect business outcomes. Parsers streamline this process for both parties — business teams and customers — leading to increased revenue and retention, decreased churn, and a company’s bottom line improvement.

How to choose the best email parser

Choosing an email parser for your team requires careful consideration. Effective parsers must provide reliable data extraction, seamless integration, advanced customization, and enterprise-level security. The right email parser will empower your team with actionable insights, boost productivity, and drive business outcomes.

Let’s look at additional factors to consider when choosing an email parser:

  • Accuracy: Ensuring reliable data extraction is paramount for a business to leverage the insights found in email data. An inaccurate parser wastes time and resources by extracting incorrect data. An ideal email parser has high accuracy rates and error correction features to ensure accurate data extraction.
  • Integrations: The best email parser should streamline workflows and increase efficiency and data visibility, which starts with integrations. Seamlessly transferring data from email to existing systems eliminates the need for manual data entry. This ensures accuracy and significantly improves your team’s workflow.
  • Ease of use: A user-friendly parser allows faster setup and deployment times, reduced training needs, and an improved user experience. This enables teams to get up and running quickly to implement the parsers into their daily workflows.
  • Scalability and supported data types: As your business grows, so will your parser needs. Consider your current and future email volume and data types. Ensure your parser supports the specific data types you’re extracting from and your growing business needs.
  • Security and compliance: Our inboxes contain sensitive information. Look for a parser with robust security measures, like encryption and access controls. If your industry has specific data privacy regulations (e.g., HIPAA, GDPR), verify that the parser complies with them.

Types of email parsers 

Selecting the best email parser for your business requires a clear understanding of your options and how well they align with your needs. There are two main approaches to consider: using a business tool for automating back-office tasks or leveraging an API to integrate email parsing capabilities into your product. Let’s explore both options to help you make an informed decision. 

Business tools for automating back office tasks

Ready-made email parsers can be quickly implemented without the need for extensive development. These tools often come with user-friendly interfaces and pre-configured workflows to help automate tasks such as data extraction, email categorization, and integration with other business systems. They are ideal for companies looking for out-of-the-box functionality to streamline their operations.

APIs for application development

APIs offer a more flexible and customizable approach to email parsing by allowing developers to integrate parsing capabilities directly into their applications. This approach provides greater control over how emails are processed and enables the creation of tailored solutions that fit specific business requirements. APIs are particularly advantageous for businesses anticipating growth and needing scalable solutions, as they can adapt quickly to evolving needs and complex use cases.

Offerings with both ready-made solutions and APIs

Some providers offer ready-made solutions and APIs, allowing businesses to choose the best option. These offerings can cater to immediate implementation needs while providing the tools for more complex, long-term integration projects.

The choice between business tools for automating back-office tasks and leveraging an API for email parsing depends on your requirements, available resources, and the degree of customization you desire. Here’s our list of the best email parsing tools in each category.
