Across the world, the post and parcel industry, via UK Postbox services and throughout the resources on this website, you may see both 'mail' and 'post' referred to.

'Mail' and 'post' essentially mean the same thing - letters, parcels, and general delivery services, but the key difference is in how they’re used regionally and contextually.

And why does UK Postbox refer to both?

Firstly, let's look at the terminology in our key regions.

🇬🇧 In the UK

In the UK, 'post' is the more commonly used word in everyday conversation. For example, people say things like 'The post has arrived' or 'I’m going to the post office.' It feels natural and familiar.

'Mail' is still used in the UK but more often in formal, commercial, or technical settings: like 'Royal Mail', 'junk mail', or 'mail forwarding'. It’s often used in business contexts such as hybrid mail services or digital mailrooms.

🇺🇸 In the US

In the US, 'mail' is the default term. Americans say 'I’m mailing a letter' or 'Did the mail come today?' The word 'post' is mostly used in specific terms like 'post office', 'postal service' or 'postage'.

Digitally, 'mail' has extended into 'email' short for electronic mail. 'Post' has developed a different digital meaning, like publishing content online (social media posts, blog posts, etc.). These two are not interchangeable.

From a branding or business perspective, especially in the UK:

• Use 'post' when speaking to general customers or in casual contexts.

• Use 'mail' in professional, technical, or product-related language for example, 'mail scanning', 'mail forwarding', or 'online mail management'.

For a business like UK Postbox, both terms are valid, but 'mail' often makes more sense when describing digital services. 'Post' works well in customer-facing content to keep things natural and relatable.

🇦🇺 In Australia

In Australia, the terms 'mail' and 'post' are both used, but there are some common conventions:

  • 'Post' is more common in everyday speech.
    • “I’ll put it in the post.”
    • “The postie delivered a parcel.”
  • 'Mail' is understood and used, but slightly less common in casual conversation.
  • The national postal service is Australia Post (often shortened to AusPost).
  • Postal workers are colloquially called posties.

Examples:

  • “Check the letterbox for today’s post.”
  • “The postie came early this morning.”
  • “I’m waiting for a parcel from AusPost.”

Common phrases with 'mail':

Mailbox - A box where mail is received or collected

Mail carrier/mailman - The worker who delivers the mail

Snail mail - Physical mail sent through the postal system

Mail service - An organisation that handles delivery

Mailroom - Traditional mailrooms where businesses physically manage their post.

Common phrases with 'post':

Post Office - The government or national delivery service location

Postman/postwoman - The person who delivers post

Posting a letter - Sending a letter through the postal service

Postal service - The broader mail delivery system
