MailParse

What MailParse is

MailParse converts email messages into structured data for spreadsheets, databases, scripts, and application workflows. It accepts .eml and .msg files, pasted raw email text, or messages from connected mailboxes, then produces Excel, CSV, or JSON output. Extracted information can include sender, recipients, date, subject, plain-text and HTML bodies, attachment metadata, and custom fields. Starter and higher plans support custom fields defined through label matching or regular expressions.

Starter and higher plans can connect Gmail or another IMAP mailbox and check for new messages every 15 minutes. The service lists integrations with Microsoft Excel, Microsoft Outlook, Google Sheets, Airtable, and Notion, along with JSON/API access. Its API provides structured JSON suitable for database imports and application pipelines. MailParse runs in a browser on Mac, Windows, or Linux without installation; its listed platforms also include API, self-hosted, Linux, macOS, and Windows. Attachment details include filename, type, and size, but the service does not extract content from PDF or spreadsheet attachments. Three parses are available without an account, and a free account receives a one-time pool of 30 parses. Starter costs $24 a month, billed at $288 yearly, with a 100-email monthly limit.

Who it suits

MailParse suits people who need to turn email files, message text, or mailbox messages into structured spreadsheet or JSON data. It also fits teams that need recurring mailbox checks, custom fields, or API output for data workflows.

Limits

Starter costs $24 a month, billed $288 yearly, and allows 100 emails per month. Uploaded files and Starter/Plus parse results are automatically deleted after 30 days. MailParse lists attachment filename, type, and size, but does not parse content inside PDF or spreadsheet attachments.

Getting started

1. Visit the MailParse website in a browser on Mac, Windows, or Linux.
2. Run up to three parses without an account, or create a free account for a one-time pool of 30 parses.
3. Upload an .eml or .msg file, paste raw email text, or choose a paid plan to connect Gmail or an IMAP mailbox.
4. Choose Excel, CSV, or JSON output, or use the API for structured JSON.

Verdict

Choose MailParse when email messages need to become structured Excel, CSV, or JSON data, especially through mailbox sync or an API workflow. Look elsewhere if you need content extracted from PDF or spreadsheet attachments; MailParse lists attachment details but not their contents.
