Is Email a Durable Medium?

Yes, email can be a durable medium

The FCA is explicit on this point.

Its guidance on durable medium says emails can be personally addressed, stored for future reference and reproduced unchanged.

Those are the core characteristics of a durable medium.

So it would be misleading to say that regulated firms cannot use email because email is not a durable medium.

It can be.

The more useful question is whether the way email is being used is suitable for the particular communication and for the customer experience the firm wants to provide.

Why email can satisfy the definition

The FCA definition of durable medium focuses on three main characteristics.

The information must be:

• addressed personally to the recipient
• accessible for future reference for an adequate period
• capable of unchanged reproduction

Email is capable of doing all three.

A message is addressed to a particular recipient. The recipient can normally retain it. And an email received at one point in time can normally be reproduced later without the sender changing the stored message.

A PDF attached to an email may also be capable of satisfying the definition. The FCA separately notes that PDFs can be clearly addressed, stored and reproduced unchanged.

Does the document have to be attached to the email?

Not necessarily.

The durable-medium question is about how the required information is provided and whether the relevant requirements are satisfied.

In some circumstances the email itself may contain the information.

In others, a document may be attached.

A link to information on a website raises a different question, because the customer may be taken to content that remains under the provider’s control and can potentially change.

Some FCA rules separately allow information to be provided through a website that is not itself a durable medium where specific website conditions are met.

So firms should check the rule that applies rather than assuming that every emailed link has the same regulatory effect as delivering the information itself.

If email works, why use anything else?

Because regulatory capability and customer experience are different questions.

Email is excellent for communication.

It is familiar, immediate and already built into most business processes.

But important customer documents can remain useful long after the surrounding email conversation has been forgotten.

A customer may receive:

• annual statements
• policy documents
• agreements
• tax documents
• regulatory notices
• confirmations
• reports
• terms and conditions

Months later, the customer’s problem may not be whether the document was successfully sent.

It may simply be finding it again.

The long-term problem with email attachments

An email inbox is organised around messages and conversations rather than around the customer’s important records.

Attachments can become buried among ordinary correspondence.

Customers may download files to different devices, rename them, delete the original email or forget which message contained the document they need.

That can lead to avoidable questions such as:

• Can you send me last year’s statement again?
• Which email contained my policy document?
• Where can I find the agreement you sent me?
• Can I still access the documents from my old account?

Email can therefore work perfectly well as a delivery channel while still being a poor filing system.

Keep email for communication

Replacing email is often unnecessary.

A cleaner approach is to separate two jobs:

Job	Suitable role
Tell the customer something has happened	Email
Send alerts, reminders and everyday messages	Email
Give the customer an important point-in-time document	Durable document delivery
Give the customer somewhere to find that document later	Long-term document access

This distinction allows businesses to preserve familiar workflows without making the inbox responsible for the customer’s entire document history.

Email and Consumer Duty

Durable medium and Consumer Duty are different regulatory concepts.

A communication method can satisfy a durable-medium requirement without automatically producing the best customer outcome.

Firms still need to consider whether communications support customer understanding and allow customers to use important information effectively.

For documents customers may need to review again later, findability and continued access can therefore matter beyond the narrow durable-medium test.

Where Documentd fits

Documentd is not based on the argument that email is non-compliant.

The proposition is simpler:

Keep the email. Give the important document somewhere better to live.

A business can continue using its normal email workflow while Documentd delivers the important document into the customer’s own Keepd document space.

The email remains the communication.

Keepd becomes the place where the customer can find the document later.

See Documentd’s durable-medium approach or compare email attachments with customer document portals.

The key point

Email can be a durable medium.

That settles the regulatory misconception.

But firms choosing how to deliver important customer documents should ask a second question as well:

Even if the inbox can hold the document, is it where we want the customer’s long-term record to live?
