The best email parsing software in 2025

受信トレイにはEメールだけではなく、データがいっぱい入っています。これは、ビジネスを経営している場合に特に当てはまります。おそらく、見込み客情報はEメール経由で入ってくるのでしょうし、特定の請求書はそこに送られるのかもしれませんし、あるいは、すべてのオンボーディング アンケートの結果がそこへ送られるのかもしれません。

But you can't do much with this data if it stays buried deep in your inbox among the newsletters, shipping notifications, and spam. Receipts are more useful in your bookkeeping software and contacts are more useful in your CRM, for example. While you could manually copy all that information over, especially if there are only a handful of relevant emails, it's still an annoying bit of work—and definitely doesn't scale to dozens or even hundreds of emails a day.

This is where email parsing tools come in. These tools do the work for you, grabbing information from your inbox and organizing it in such a way that other apps can make use of it. Email parsing apps are distinct from powerful email clients like Superhuman and Shortwave that make it easy to find and sort data in your inbox—instead, they're designed to get data from your inbox to somewhere more actionable. Even the best email apps leave most data sitting buried somewhere in your mail.

For years, email parsers were kind of awkward to use. You had to manually create rules using things like regular expressions, if-this-then-that logic loops, and other kinds of code and pseudocode. If you could fine-tune things, amazing—until the format of the emails you were scraping changed and you had to update things all over again. But over the past few years, there's been a big technology shift: now you can parse emails using AI.

そして、これは本当に大きな変化です。大規模言語モデルは柔軟性が高いため、Eメールから日付を取得して特定の形式でフォーマットするように指示すると、Eメールで日付がどのように表示されるかに関係なく、その通りに動作します。すべてが正しく機能するためにはまだ調整が必要ですが、Eメール解析ツールはもはや、奇妙に特殊なルールでまとめられた扱いにくいルーブ・ゴールドバーグ・マシンではありません。 

したがって、Eメール解析ツールに興味があるだけの場合でも、よりシンプルなツールにアップグレードすることを検討している場合でも、現在利用可能な最高のEメール解析アプリがここにあります。

最高のEメール解析ソフトウェアとはどのようなものでしょうか?

There are only a dozen or so true email parsers available, so I tested every one I could get my hands on and selected the best. I've been testing and reviewing automation software for well over a decade, so I have a lot of experience evaluating apps like this. The best email parsing apps meet the following criteria (and some go above and beyond):

• They extract specific information from your email and its attachments. The best apps use AI models to detect relevant information, though you can tweak things using custom rules and templates. Accuracy is important here as you need your email parser to reliably grab the data you want every time.

• They're easy to set up and use. Email scraping services used to be pretty tricky to set up. You had to manually create a series of rules that would extract the data you wanted from an email. Now though, AI can do a huge amount of the heavy lifting for you. Even compared to a few years ago, the email parsing tools available are genuinely easy to use. It's a big change, and it's really shaken up the list.

• They put that data where you want it. Email parsing apps are about getting data from your inbox to somewhere more useful. You want your receipts sent straight to your accounting software, or your new clients' contact details added to your CRM and mailing list automatically. 

• 使い勝手がいいです。 Eメールパーサーなどの専用ツールは、多くの場合、技術的なエンドユーザーを念頭に置いて構築されます。つまり、多くのアプリでは、オンボードや優れたUIなどの機能が省略されています。必須ではありませんが、役立つヒント、チュートリアル、不快感を与えないインターフェースにより、最高のEメールパーサーは、より快適に使用できるようになります。これらは確かにすべての人向けのアプリではありませんが、理想的には誰にとっても使えるアプリであるべきです。

場合によっては、異なる価格帯で同様の機能と品質を提供するアプリが見つかり、その場合は、より手頃な価格または使いやすいオプションを優先しました。

なぜEメールを解析するのですか?EメールパーサーとEメールルールの比較または違い

Gmail や Outlook などのほとんどの電子メール サービスには、 Eメールをフィルターしたり並べ替えたりするために使用できる何らかの自動化されたルール システムがあります。専用のEメールパーサーとこれらのルールの違いは、1 つの重要な違いに集約されます。Gmail と Outlook はEメールをそのコンテンツに基づいて並べ替えることができますが、Eメールパーサーはコンテンツを直接並べ替えることができます。

たとえば、Gmail を使用すると、請求書が含まれるすべてのEメールに自動的にタグを付けることができるため、年末に会計担当者に送信することができます。メールパーサーを使用すると、送信日、請求書番号、支払い日を抽出し、Zapier などのアプリを使用してそれをスプレッドシートに追加し、毎月第 2 火曜日に会計担当者に自動的に送信することができます。

多くの人は、おそらくEメールサービスに組み込まれている自動化で十分でしょう。しかし、ビジネスを運営していて、Eメールに実際に含まれているデータを処理する必要がある場合、処理すべきEメールが大量にある場合、またはこうした種類の処理を自動化することが好きな場合は、Eメールパーサーが最適です。

Best email parser for getting email data into your other apps

Zapier (Web)

Zapier Pros:

• Option to use structured parsing or an AI agent

• Easy to set up and use either way

Email Parser by Zapier Cons:

• Not a dedicated email parser

This is a Zapier product in a Zapier blog post, so I understand if you're skeptical about my ability to be neutral. But if your goal is to get data out of your inbox and into all the other apps you use at work, Zapier has a couple options that make it easy.

Get started with Email Parser by Zapier, and you can set up as many mailboxes as you want, each with its own @robot.zapier.com email address. You can forward emails to that address, either manually or using something like Gmail's filter system. Send a few sample emails, then highlight and name the information you'd like to scrape from future emails. You won't find many advanced features here—you can't scrape the contents of email attachments, for example. Then you'll set up a Zap, Zapier's term for an automated workflow, which is what will send that information to any other app you want—you can choose from thousands of apps, or even send the contents off to be handled by an AI like ChatGPT.

Alternatively, if you want to leave the decisions in the hands of AI, you can do this all using natural language with Zapier Agents. Your agent can watch your inbox for whatever emails you're looking for (based on sender, label, or any other feature), and then pull out the information you need. Once it has that information, it can send it to 8,000+ other apps, so you can get data from your inbox into a spot where it's actionable.

A few examples of what you can do with the scraped contents: send information from your email to a spreadsheet, add new contacts to a Mailchimp list, or create a Google Calendar event based on the specified time and date in the email. Zapier is an AI orchestration platform, so you can build complex systems that run on their own. Learn more in the guide to Email by Zapier and the guide to Zapier Agents, or get started with one of these pre-made templates.

Zapier pricing: Free plan available; paid plans from $19.99/month

Best dedicated email parser

エアパーサー (Web)

Airparserの長所:

• 驚くほど使いやすい

• Powerful AI-powered email parsing

• プロンプトを使用すると、データを抽出して構造化できます

Airparserの短所:

• 特に低料金プランでは高価です

Airparser is an AI-powered email parser developed by Parsio, one of the other apps on this list. It's a separate product because it depends almost entirely on large language models to extract information from your emails, PDF documents, text files, and with OCR, even images. It's super powerful and really easy to use. (If I had to hazard a guess, I'd say its custom AI models are based on Llama.)

With Airparser, every inbox—though you can also upload files manually or using the API—has its own extraction schema. This is what structures the data you're trying to pull from an email, document, or other file. I found its auto-generated extraction schema did a great job of pulling out every actionable piece of data, though you can also write your own prompts if you don't need every single detail. 

Best of all, Airparser automatically formats things as JSON, so you can use its built-in Python post-processing to manipulate it, send it to a Google Sheet, or send it to almost any other app using Zapier. This means you can do things like send all your transactions straight to your accounting software or add new contacts to your CRM. Learn more about how to automate Airparser, or get started with one of these pre-made templates.

The big downside is the price. The Starter plan costs $39/month and only gets you 100 credits per month—that means each processed email costs $0.39. Things are much better on the $59/month Growth plan (500 credits per month/~$0.12 per email) and $179/month business plan (2,000 credits per month/~$0.09 per email). So if you're a high-volume user, Airparser could be quite good value—but if you're only parsing a few dozen emails per month, it'll be a pricey option. 

Airparser の価格: 30クレジットの無料トライアル、月額100クレジットのStarterプラン (月額 $ 29から)

最高の多目的Eメールパーサー

パルシオ (Web)

パルシオの長所:

• 超柔軟

• Affordably priced

パルシオの短所:

• AIがデータを抽出する方法をAirparserほど制御できない

Parsio has a lot in common with Airparser—which is no surprise given that both tools were built by the same team. It offers GPT-based parsing, PDF-parsing using pre-trained AI models, and template-based parsing so it's one of the most flexible tools on the list. 

With GPT-powered parsing, you simply write a prompt directing it to do something like "extract the conference link, names of attendees and their email addresses, and the agenda" or "find the time of the meeting and convert it to EST" from almost any kind of document. If you've ever tried something similar with ChatGPT, you'll know how good AI can now be at this kind of thing.

The pre-trained PDF and image parsing is super interesting. Parsio has AI models to extract content for invoices, receipts, tax forms, ID documents, and other kinds of documents. They can also use OCR to extract data from scanned and handwritten documents. I found it did a really good job of pulling out all the information from my invoices. 

The template-based parsing is also good if you have a document where nothing changes. You select a chunk of text in your sample document and assign it to a data field or table. If things stay the same, it will work—but if something changes in the format of the email or document, your email parsing will break. It's the cheapest option though.

Parsio works using a credit system. It costs one credit per page to use the template-based parser (and an additional one credit to parse an email signature), two credits per page to use the GPT-powered parser, or five credits per page to parse an attachment with a pre-trained AI model. Paid plans start at $49/month with 1,000 credits.

Parsio は後処理機能を提供し、Slack、Shopify、 Zapier を含む他の多数のアプリとネイティブに統合されます。つまり、解析されたドキュメントから Google Sheets や Airtable のレコードを自動的に作成するといったことが可能になります。さらにいくつかの例を示します。

Parsio pricing: Free trial; from $49/month for Starter plan with 1,000 credits/month.

上級ユーザーや添付文書の処理に最適なメールパーサー

パーサー (Web)

パーサーの長所:

• 優れたテンプレートと堅牢なAIを備えた、フル機能で柔軟なEメールパーサー

• まともな無料プラン

パーサーの短所:

• 特に低料金プランでは高価です

Parseur is another flexible email parser like Parsio. Its AI-assisted mailbox creation does a great job of turning your example emails and documents into a template, though you can still use a predefined category like financial statement or invoice. It works with both emails and an inexplicably long list of file formats. If you need to pull a contact number from an ODT, RTF, Apple Pages, or even a WordPerfect file for some reason, it has you covered. It's also got some pretty powerful OCR features, like dynamic OCR that can find fields that move or change size in a document or email.

AI の点では、Parseur は Airparser と Parsio の中間に位置します。抽出した内容をもう少し直接操作することはできますが、Airparser が提供するのと同じレベルの制御とカスタマイズはできません。

そして、好きになるものもたくさんあります。たとえば、 Python スクリプト(価格は高め) を使用した後処理サポートや、 Zapierなどの多くの統合があり、メールからスクレイピングしたデータを何千ものアプリに送信できます。Parseur を自動化する方法について詳しくは、こちらを参照してください。または、あらかじめ作成されたワークフローを試してください。

The downside: Parseur's credit system can be expensive. It costs one credit to parse one email or one page of an attachment. The free plan gets you 20 credits/month, but after that, the cheapest plan is 100 credits/month for $49. $0.49 per email or page of an attachment might be worthwhile if you want access to both a template system and an AI, and the price per credit goes down rapidly with higher monthly fees, so try Parseur out before you decide on a service.

パーサーの価格: Free for 20 documents a month。月間100クレジットのプランの場合は月額 $ 49から。

その他のEメール解析ソフトウェア

AI has dramatically changed email parsing in the last couple of years, which is awesome for users, but it's meant that some apps I used to love now feel a bit dated. With apps like Zapier, Airparser, Parsio, and Parseur making it super easy to extract data from emails, there's now no reason for most people to use a tool that makes things a bit more awkward. 

それでも、技術的な側面に慣れている場合や、少し違うものを求めている場合は、検討する価値のある他のEメール解析アプリがいくつかあります。

• Mailparser (which you can automate with Zapier) had one of my favorite template setups, but its AI features aren't as solid as the options on this list. 

• Parserr has some neat AI features, but the interface is a bit confusing and it requires a demo call to try out.

• Nanonets has some of the most powerful AI parsing features around, but everything about it is kind of confusing. Its pricing model is very opaque, it isn't really aimed at emails, and I struggled to get it set up. 

• Email Parser is the only service I looked at with a desktop Windows app. If that's what you want, give it a look, but it feels very dated.

• SigParserは、電子メールを検索し、署名内のすべての連絡先の詳細を取得できます。今年はリストに載るには少し制限が多すぎましたが、サービスはしっかりしています。

現在の AI ブームにより、かつては複雑だったアプリが使いやすいノーコード ツールに変わっていくのを見るのは、とてもわくわくします。チャットボットなどは大いに宣伝されていますが、個人や企業が毎日使っているツールに対するこうした控えめなアップグレードも同様に大きな影響を与える可能性があります。いまだに、古臭い Gmail ルールを使ってEメールを解析したり、スプレッドシートにコピーして貼り付けたりしているなら、これらのアプリを試してみてください。
