Email Extractor

Email Extractor

Our Email Address Extractor simplifies the process of finding email addresses in a block of text or document. Whether you're managing customer lists or conducting research, this tool is designed to enhance your experience in handling email address data.

How to Use

• Copy and paste the text or document containing emails into the provided area.
• Initiate the extraction process by clicking the "Extract" button.
• The tool will search through the text and display all discovered email addresses directly within the same text area.

Email Address Syntax

The email address format, as defined in  RFC 5321, RFC 5322, RFC 6531, and  RFC 6532, can be briefly summarized as follows:

• An email address consists of a local part and a domain part, separated by an at-sign ("@”) - "local-part@domain".
• Maximum length:  
  • Local part: 64 octets; 
  • Domain part: 255 octets; 
  • Each domain label (subdomain):  63 octets; 
  • Entire email address:  320 octets.
• The local part may include alphanumeric characters (including Unicode), along with the special characters: !, #, $, %, &, ', *, +, -, /, =, ?, ^, _, `, {, |, },  ~, and possibly with periods (“.”), though not at the start or end. Consecutive periods are not allowed.
• The local part may be also formatted as a quoted string, consisting of letters, digits,special characters, and spaces enclosed in double quotes ("). 
• The domain part adheres to the standard  LDH rule, encompassing letters (including Unicode), digits, and hyphens (“-”). Hyphens may not appear in the first or last position.    

Note: While our tool complies with most email address format requirements, it does not perform length validation.

“mailto” URI Handling

This Email Extractor tool is designed to extract email addresses embedded within “mailto” URIs present in the provided text. Moreover, it also decodes  any percent-encoded Unicode or special characters within email addresses, presenting them in their original, human-readable form.

What is “mailto” URI?

A "mailto" URI (Uniform Resource Identifier) is a specific type of URI that is used to create hyperlinks that, when clicked, initiate an email composition process. Essentially, it's a way to specify an email address and other parameters, such as the subject and body of the email, in a URL-like format. The "mailto" URI scheme is defined in RFC 6068.

Here's the basic structure of a "mailto" URI:

mailto:address@example.com?subject=Subject%20Here&body=Message%20Body

• mailto: This is the scheme that indicates the URI is a "mailto" link.
• address@example.com: This is the email address of the recipient.

In addition to specifying the primary recipient's email address in a "mailto" URI, you can include other parameters to address the email to specific recipients. The parameters include "to," "cc," and "bcc," each followed by an equal sign and the corresponding email addresses:

• "to=": This parameter is used to specify the primary recipient of the email.
• "cc=": This parameter is used to specify email addresses that will receive a copy (CC) of the email.
• "bcc=": This parameter is used to specify email addresses that will receive a blind carbon copy (BCC) of the email. BCC recipients are not visible to other recipients.

These parameters can be combined to address emails to multiple recipients and include CC and BCC recipients in the same "mailto" link:

mailto:jane.doe@example.com?to=bob.jones@example.com&cc=marketing-team@example.com&bcc=ceo@example.com&subject=Project%20Discussion&body=Let's%20meet%20to%20discuss%20the%20project%20details.

In this example, the email is addressed to jane.doe@example.com, with additional recipients specified by the "to," "cc," and "bcc" parameters.
