How to Write a Professional Email in French

You wrote a perfect sentence. Then you stared at the greeting for eleven minutes. Bonjour? Madame? Madame, Monsieur? Or the terrifying Cordialement, which sounds like something a notary would say at a funeral.

French email etiquette is not decoration. It is signalling, and getting it wrong reads as either cold or overfamiliar. Here is the whole system, in order.

What you will get from this guide

  • The exact greeting, body and sign-off sequence French colleagues expect
  • Vouvoiement rules that stop accidental rudeness
  • Copy-paste templates for requests, follow-ups and apologies

The Skeleton of a French Business Email

French professional email follows a fixed choreography. Skip a step and the message feels abrupt, even when the words are polite.

PositionElementPurpose
1SalutationEstablishes respect and distance
2Opening formulaSignals why you are writing
3Body paragraphsThe actual request or information
4Closing formulaSignals the end, softens the ask
5Formule de politesseThe formal sign-off
6Signature blockName, role, contact

Six slots. Fill them all, every time. This is not stiffness — it is the grammar of politeness.

Greetings: Choose One and Do Not Blend

French greetings are forgiving once you know the tiers. The mistake is inventing hybrids like Bonjour Madame Dupont in an email to a stranger.

SituationGreetingNotes
Unknown recipientMadame, Monsieur,Safest default
Known name, formalBonjour Madame Dupont,Common in modern offices
Same company, seniorBonjour Monsieur,Keeps distance
Colleague you knowBonjour Claire,Normal at B1 workplace level
Client you have never metMadame, Monsieur,Never first-name them

Two rules. In a formal email the greeting ends with a comma, and the next line starts with a capital. And never use Salut in writing unless you would text that person about weekend plans.

Vouvoiement: The Rule That Saves You

Tu versus vous is the single biggest risk in a French business email. Getting it wrong is not a grammar slip. It is a small social incident.

ContextDefaultWho can switch
Client or prospectvousThe client, rarely
Manager or directorvousSenior party
Same-team peer, first contactvousEither, explicitly
Supplier or adminvousAfter some time

The golden rule: you may offer tu, but you may never take it. If a client writes tu to you, mirroring it is usually acceptable in France — but in many Belgian, Swiss and African French business contexts, staying on vous is safer. When in doubt, vous.

Opening and Closing Formulas That Work

French has stock phrases for every move. Use them. Native speakers read originality here as uncertainty.

FunctionFrench formulaEnglish sense
OpeningJe me permets de vous écrire au sujet de…I am writing regarding…
Following upJe reviens vers vous concernant…I follow up about…
RequestingJe vous serais reconnaissant(e) de bien vouloir…I would be grateful if you would…
AttachingVeuillez trouver ci-joint…Please find attached…
ClosingJe reste à votre disposition pour tout complément d'information.Happy to provide more information.
Sign-offCordialement,Standard professional
Sign-off, warmerBien cordialement,Slightly warmer standard
Sign-off, formalVeuillez agréer, Madame, l'expression de mes salutations distinguées.Very formal

Note the trap. Cordialement is the workhorse and works almost everywhere. The long formule de politesse is reserved for genuinely formal correspondence — using it for a routine internal note sounds like a legal notice.

Mistakes That Cost You Credibility

Small slips, big impressions. These are the ones French colleagues notice.

MistakeWhy it lands wrongFix
Tu with a clientReads as disrespectDefault to vous
No formal sign-offReads as brusqueAlways add Cordialement
Literal translation"Dear John" becomes oddUse Madame, Monsieur
No space before punctuationLooks sloppy to French readersFrench puts a space before ! ? ; :
Long apology paragraphsReads as weaknessOne sentence, then move on
All caps subject lineReads as aggressionUse normal case

The punctuation one is genuinely French-specific. In French typography a space precedes !, ?, ;, : and the guillemets « ». Miss it and your text looks hand-typed in a hurry.

Practice That Actually Transfers

Reading templates is not learning them. Do this instead.

WeekDrillOutput
1Rewrite five of your own emails in FrenchFive polished drafts
2Read a French invoice or quote requestVocabulary list
3Have the AI tutor review two draftsCorrected versions
4Write one email with no dictionaryReal test

By week four you will produce a correct business email in under ten minutes. That is the B1 workplace benchmark, and it is exactly where DELF B1 writing tasks live.

Frequently Asked Questions

Is Bonjour too informal for a business email? No. Bonjour is standard and safe in modern French professional writing. What matters is what follows: use Madame or Monsieur, never only a first name with a stranger.

Which sign-off is best in French? Cordialement is the safe default for almost every professional email. Reserve the long formal formulas for official or legal correspondence.

Do I always use vous in a french business email? Yes, by default. You may offer tu only when the other person explicitly invites it. Let the senior or client side make the first move.

How do I handle gender in formal French formulas? Use the parenthetical form, reconnaissant(e), when you do not know the recipient's gender, or rephrase the sentence to avoid the adjective entirely.
