7 Best Email Parsers in 2024

Your business email inbox is much more than just unread emails and attachments β€” it’s a treasure trove of data. Data that needs to be manually extracted and sent to a particular business software.

Businesses receive a ton of emails every day with invoices, receipts, quotes, leads, contact information, order confirmations, delivery updates and more.

Then follows the daily drudgery of sifting through emails to pick out important ones. And manually extracting specific data to be added to Google Sheets, CRMs, ERPs, accounting software or other business applications.

Imagine doing this manually for hundreds or thousands of emails – and the resulting bottlenecks! This process just can’t scale – especially for large businesses. This is the reason many businesses are turning to email parsing solutions.


Email parsers can help automate or optimise email data workflows to a large extent.

An email parser or email extractor is a software that can classify incoming emails and attachments, extract specific data from them and export it to other business applications.

In this article we review some of the best email parsing software and how they can optimise your email data entry workflows.

Why parse emails?

Email data extraction is quite a challenging problem to solve. Email data is unstructured – they have no schema. Emails come in multiple formats and there is no standardized representation.

Classifying emails, recognising email data, and extracting just the relevant information requires a combination of automation, rules and cognitive data capture. This is what email parsers do.

Why should you consider email parsing for your business? Here are some of the benefits of adopting email parsing:

  1. Parsing emails with a software is faster and more accurate than the manual alternative.
  2. Email parsers can be automated to extract vital data from incoming emails – without any manual intervention.
  3. Data can be extracted from the email header, body, signature and attachments (PDF, image or other files) – all without ever having to open the email!
  4. Incoming email data can be classified and sent to appropriate business applications (CRMs, ERPs etc.) – forget manual copy pasting.


Did you know you could automate book-keeping with email parsing? For example, an email parser can pull out all relevant invoice data (dates, amounts, vendor details etc.) from emails/attachments and update entries on Quickbooks, Sage, Netsuite or any other accounting software.

How to pick the ideal email parser?

In this post we look at just the top seven email parsing software in the market.

There might be even more out there. But which one is the best for you?

Here are some pointers to keep in mind when selecting the most ideal email parsing software for your business:

Use case

The email parser you need will mostly depend on the kind of data you wish to parse from your incoming emails.

Do you need to parse data only from email bodies or metadata such as headers and timestamps? Do you also need to extract data from attachments, PDFs or images?

Template vs rule-based vs cognitive email parsing

If you’re looking for an email parser, you mostly need to extract just some specific data or fields from your emails?

Do you receive emails in the same format, with data exactly in the same position across all emails? Do you want to setup rules to define/specify the data in each email? Or do you need an email parser that will automatically pick out all the relevant data?

Data integrations

Email data is mostly parsed so that it can be sent to a specific business application for further downstream processing.

Can your email parser integrate seamlessly with Google Sheets, CRM, ERP, accounting software, databases or even Slack? You will need to check if the email parser can improve your current processes without changing existing workflows.

Data transformation

Can the data parsed from your emails be processed, transformed or modified into other formats? Business applications might only ingest data that is imported in specific file formats or structures.
