What is an attachment in digital marketing and email marketing?

In the context of digital marketing, an attachment refers to any file or content added to an email or text message.

It can be an image, a document, a link, a video or any other type of multimedia file.

Attachments are crucial because they complement or expand on the main message you want to send.

The role of attachments in digital marketing

Attachments play a multifaceted role in digital marketing.

They add value and clarity to messages, helping to convey an idea or concept more effectively.

In the context of a web page, for example, an attachment could be an image or video that illustrates a product or service.

Attachments in email marketing campaigns

In email marketing campaigns, attachments can be very useful tools.

They may include product catalogs, information leaflets or discount coupons.

However, it is important to use them with caution.

Large files or files with questionable extensions could activate the filter radars and the emails could be flagged as spam; this means the message could be blocked, not delivered or not load correctly.

Additionally, you need to ensure that attachments are relevant and add real value to the message.

Best practices for using attachments

  • Relevance: The attachment must be directly relevant to the main message.
  • Quality: Ensure files are high quality and optimized for fast loading.
  • Security: Check that attached files are virus-free and safe for the recipient.
  • Clarity in instructions: If the attachment requires a specific action, such as downloading a file, it is essential to provide clear instructions.

Common mistakes when using attachments

  • Too many attachments: Too many attachments can be counterproductive.
  • Ignoring mobile optimization: Not all attachments display well on mobile devices, which is crucial given the high usage of smartphones.
  • Lack of personalization: Generic attachments can look impersonal and reduce the effectiveness of the message.


Attachments, whether in emails, text messages or web pages, are fundamental elements in digital marketing.

Its correct use can significantly improve communication with the public, increase engagement and increase the effectiveness of marketing advertising campaigns.

It is essential, however, to use them strategically, ensuring that they complement and reinforce the main message, without overwhelming or confusing your subscribers.
