As the heading suggests, I'm wondering whether there is a formal word or phrase for "snail mail", that can be used in contexts where we want to make clear that we're not talking about emails. For instance:

All communication should be conducted in writing, via XX or email

where XX stands for a more formal word for "snail mail".

Edit: I realise from all your answers and comments that I should have added the geographical context as well – primarily I need it for a British/European context, but I'm interested in the regional differences too, so I'm very grateful for all perspectives :)

  • "postal mail" or just "post"

  • It is more formal, but clearer, to use "through the post" than just "post". So you might say "contact me by email or through the post".

According to the reasons I outline in this answer, the best options seem to be:

Most natural British English: email or post.
Most formal British English: postal mail or email.
Best for germanic language natives: email or post.
Best for British and trans-European English: email or postal mail.

Why not "mail or email"?

"Mail or email" is not a good solution in my opinion (for British and European English speakers).

In British English, which the OP is asking about, "mail" is already weird. "Post" is the word that we use in everyday speech to specify postal mail.

For Europeans who have learnt English, "mail" would be very easily confused for "email". Not just because they are so similar morphologically, which makes it hard to distinguish them in the first place, but also because of their native languages: romance languages seem to slowly be giving up on distinguishing between "mail" and "email" (even more so than English); and "post" is a germanic word, so German natives, Dutch natives, etc., will find anything containing "post" easier to notice and understand than when it doesn't appear.

"Mail or email" is also weird, and that's for English in general — not just British English! In these kinds of contrast-patterns, readers expect like-nouns (in this case "mail") to have contrasting qualifiers. Perhaps this idiomatic pattern has arisen from generations of writers intentionally disambiguating the two sides. "Would you prefer to be seated in a carriage or a club carriage?" is very weird. Even though "carriage" can normally be used alone for exactly the same meaning, in juxtaposing cases like these it's expected to add the qualifier explicitly: "would you prefer to be seated in a normal carriage or a club carriage?"

To betray this expectation is a poetic technique, so it's not necessarily incorrect to say "hey, would you rather sit in a chair... or a deluxe ACME-pro gaming chair?" But it is a stylistic decision that has to be intentionally made, and in "mail or email"... are you sure your readers will appreciate the poetical surprise? Or even be reading slowly enough to notice "postal mail" is an option in the first place?

Any solution which uses a "post" qualifier to contrast from the "e-" qualifier in "email" would suit far better than just "mail", so e.g. "postal mail and email" is a great solution.

"email or X" vs "X or email"

Because of the way that we are naturally inclined to organise stress in English speech, "email or post" and "email or postal mail" sound more fluent than "post or email" and "postal mail or email".

"Email or post" is pronounced with a dactylic pattern: email or post. This rolls off the tongue, sounding rhythmic, casual, and non-agressive. In everyday colloquial speech, we'd likely say this.

"Post or email" however is harder to pronounce. If pronounced trochaically, "post or email", it sounds curt. Any other pronunciation, for example "post or email" (the most likely one imo), reassigns syllabic stress, either sounding muddier (less well-enunciated) and/or violating the standard stress pattern of the words, which also deteriorates clarity. By the way, the trochaic pronunciation "post or email" may be desirable, especially in a formal setting: somewhat stilted, carefully-enunciated speech is a common sight in formal settings. This might be because it dispels laziness and casualness.

Similarly, "email or postal mail" is naturally a dactylic dimeter ("email or postal mail"), that has the same positive connotations as before. It also agrees with the isolated pronunciation of "postal mail", which is a dactyl ("postal mail"), because "postal mail" is one conceptual unit so outside of metrical context it would tend to be pronounced as a whole. In some contexts, "mail" can be a stressed syllable ("the postal mail was slow today" — very satisfying iambic tetrameter), but in your case it's at the end of a sentence. "Postal mail or email" has the same rhythmic consequences as "post or email".

Whether or not anyone will notice (let alone care) outside of poetry is another question; this metrical effect could reasonably be considered negligible, especially in writing, especially in written communications.

So, my favourite solution to your question would be the totally unambiguous at-a-glance "email or post" that also uses the idiomatic most common words and ordering (for British English). It's the natural British English phrase.

According to a French friend who has learnt English in France (and online; admittedly, the internet is quite Am.Eng.-saturated, but learning through online immersion is more than common enough to matter these days), "post" is weird, so depending on your audience you may prefer to use the totally-specified "postal mail". "Postal mail" also sounds even more formal than just "post".

    This is such a good answer! And I totally agree with what you say about Europeans learning English – which is also true of Europeans borrowing English words: in Swedish, for instance, we use the word "mail" or "mejl" for 'email' (that is, that's the "Swedish" word meaning 'email'), and I'm pretty sure most Swedes would use the English word "mail" to mean 'email' when they speak English, so... Excellent points you've made here :) And great summary at the end!

In British English, the term used is "post" (never "postal mail").

Business customers can now reply to requisitions online, even if they sent us the application through the post. (UK government website)

A Notice of Appeal and accompanying documents may be delivered to the EAT by any method, such as email, fax, post, courier, or hand-delivery. (Employment Appeal Tribunal: Practice Direction, 2018 - PDF)

Oxford's definition is:

post mainly British mass noun: The official service or system that delivers letters and parcels. ‘winners will be notified by post’ ‘the tickets are in the post’ ‘I was attracted by this submission, which seems to me to gain some force from the provisions relating to service by post.’ ‘Rule 99 makes it plain that section 8 is subject to the provisions for service by post.’ ‘Service by post on the Second Defendant was not permitted.’ (Lexico)

    @BruceWayne In the UK companies like FedEx, UPS, DHL etc provide courier services, not post. "Post" specifically means "items delivered by Royal Mail" (which is roughly of the equivalent of the USPS in America).

    @alephzero good point, although technically same here in the US (they're couriers). But given all the comments and answers (and no clarity from OP for a BrE or AmE answer) I'd say a combo of "post" or "courier" with examples would work.

If you say "mail or email" in that sentence then you're explicitly making a distinction between the two. Use "mail" thereafter for physical letters and "email" for (surprise!) emails. "Mail" as a term for posting physical letters is common to both British and American English, which is a bonus.

If this is a document with legal significance (for example banks saying how they'll communicate with you), there will probably be a definition of terms somewhere saying "Mail means any physical document sent through postal or courier services" and "Email means electronic mail as defined by standard RFC5532", or something like that. If you feel the need to be completely unambiguous, feel free to use something of this form yourself.

Edit: As suggested by @ChrisH, if you specifically need a written version of a document then you can also make your instructions unambiguous by saying "this must be sent by mail, not email".

  • This might be perfect in American English, and is admittedly fine for British English too, but I think "mail or email" is not a great solution considering the OP's actual case: "British or European English". I wrote an answer for why I think so: ell.stackexchange.com/a/299103/29750

I'd use physical mail or postal service depending on if you want to emphasise the type of format or the type of courier. Both of these terms would be universally understood to be not email, both in American and in British English. Though the term post is rare in American, the traditional courier is USPS, the United States Postal Service. Though the term mail is rare in British, the traditional courier is Royal Mail.

    I agree with "physical mail" in AmE. The USPS uses the term on some of their help pages, and their blog post about Informed Delivery from a few years ago uses the subtitle Bridging the Gap Between Physical Mail and Email

  • @nasch: American English actually distinguishes between the adjective "postal" (generally understood as relating to the USPS or the local equivalent) and the noun "post" (generally understood to mean a tall, skinny support beam, oriented vertically, might be recognized as a British-ism for "mail"). This probably makes very little sense to people whose native language is more morphologically regular than English.

I'd use the word 'Post.' You can say 'post mail' or simply 'post.' It can describe the method of delivery or the items themselves.

You can say:

  • Can you put this in the post/mail please
  • Could you post/mail me a copy
