With email breaches affecting 28,550 people, it's unsurprising that understanding the niche parts of email communication becomes increasingly necessary. MIME, or Multipurpose Internet Mail Extensions, is a standard that enhances traditional email systems' capabilities.
What is Multipart MIME?
MIME, or Multipurpose Internet Mail Extensions enables the seamless integration of diverse types of data, such as text, images, audio, and video, into email messages, transforming email from a text-only medium to a rich multimedia experience. In the broader scope of internet communication, MIME plays a role by standardizing the way different types of data are encoded and transferred over the internet.
The term "multipart" within MIME specifically refers to a format that can encapsulate multiple distinct entities or parts in a single message. Each part, which can be a different type of content, is separated by a boundary. This multipart feature allows for the combination of text, images, files, and other media types within a single email.

How does a multipart MIME format differ from other MIME formats?
A multipart MIME message consists of several distinct parts, each structured to handle different types of content within a single email. At the start, the message features standard email headers like 'From' and 'To', followed by a 'MIME-Version' header and a 'Content-Type' header indicating its multipart nature and defining the boundary. This boundary is a unique text string that separates each section of the message.
Each part within the message then starts with its own set of headers, specifying the type of content it contains (like 'text/plain' or 'image/jpeg') and the encoding used. Following these headers, the body of each part contains the actual content, be it text, HTML, or binary data for attachments. Finally, the message ends with the boundary string followed by two hyphens, marking the conclusion of the multipart content.
Is multipart MIME possible to be used in healthcare?
Healthcare professionals often need to send complex messages that combine text with attachments, like patient reports, medical images, or documents. Using multipart MIME, a doctor can email a patient's medical history or consultation notes in text format, along with attached X-rays or lab results in different file formats. Similarly, multipart MIME facilitates the secure sharing of electronic health records (EHRs) between healthcare providers, ensuring that both textual data and associated media are transmitted together seamlessly. This format also supports the inclusion of HTML content for more visually engaging and informative emails, such as health newsletters or patient education materials.

FAQs
Can all email clients read Multipart MIME emails?
Most modern email clients support Multipart MIME and can display its different parts correctly, though older or simpler clients may only show the plain text version.
Is Multipart MIME format secure?
While the format itself is not a security feature, it can be used in conjunction with secure transmission methods like TLS to protect the contents of an email.
What is a MIME boundary?
A MIME boundary is a unique string that separates the different parts of a Multipart MIME email.
