Formal Business Letter (B2)

Formal Portuguese business correspondence is bound by strict genre conventions. The opening (Exmos. Senhores), the set-piece phrases (Venho por este meio..., Serve a presente para..., Agradecendo desde já a atenção dispensada...), the conditional of politeness (agradeceria, seria grato), the 1st-plural institutional voice (vimos pela presente solicitar), and the closing formula (Com os melhores cumprimentos) — these are not ornamental flourishes. They are the genre itself. A Portuguese manager reading a business letter that skips them will read it as either naive, foreign, or disrespectful.

This page presents a formal complaint letter from a customer to a telecom company — one of the most common real-world scenarios in which a B2 learner will need to write formally in Portuguese. After the letter, we walk through every set phrase and every grammatical choice, so you know what each formula is doing and why it has to be there.

The letter

Ana Maria Figueiredo Cardoso Rua das Amoreiras, 142, 3.º Dto. 1250-123 Lisboa ana.cardoso@exemplo.pt 912 345 678

Lisboa, 14 de abril de 2026

Exmos. Senhores,

Departamento de Apoio ao Cliente Empresa de Telecomunicações, S.A. Av. da Liberdade, 45 — 1250-140 Lisboa

Assunto: Reclamação formal relativa ao contrato n.º 45678321

Serve a presente para apresentar uma reclamação formal relativa ao serviço de internet e televisão contratado com V. Exas., ao abrigo do contrato acima identificado, celebrado no passado dia 3 de fevereiro.

Venho por este meio informar que, desde a instalação, o serviço tem apresentado falhas reiteradas — interrupções diárias da ligação, velocidades substancialmente inferiores às contratadas e total indisponibilidade nas horas de maior utilização, nomeadamente ao final da tarde. Apesar de terem sido apresentadas três reclamações anteriores por via telefónica (refs. 11223, 11498 e 12001), não foi até à data adoptada qualquer medida eficaz para a resolução do problema.

Face ao exposto, agradeceria que, no prazo máximo de dez dias úteis, V. Exas. se pronunciassem sobre o assunto, indicando as medidas a adoptar para a reposição do serviço nas condições contratadas. Caso tal não se verifique, ver-me-ei obrigada a apresentar queixa junto da ANACOM e a solicitar a rescisão do contrato sem lugar a penalização, nos termos da legislação aplicável.

Agradecendo desde já a atenção dispensada, e ficando a aguardar a vossa resposta, subscrevo-me,

Com os melhores cumprimentos,

Ana Maria Figueiredo Cardoso

Grammar in action

The letter is built from a sequence of formulas, each of which plays a specific role. Let's go through them in order — headers and opening first, then the body, then the closing.

1. The sender block and date line

Lisboa, 14 de abril de 2026

Lisbon, 14 April 2026

Portuguese formal letters begin with the sender's full name and address at the top, the date in CIDADE, DD de MÊS de AAAA format (with the city), and then the recipient's details. Months are lowercase in Portuguese: janeiro, fevereiro, março, abril, maio... — a frequent mistake for English speakers is to capitalise them. Note also the ordinal abbreviation 3.º Dto. ("3rd right-side flat") — Lisbon addresses typically include floor and side, abbreviated as Esq. (esquerdo, left) or Dto. (direito, right).

2. The opening address: Exmos. Senhores

Exmos. Senhores,

Dear Sirs, (literally: Most Excellent Sirs)

This is the fundamental formal opening in Portuguese business correspondence. Exmo./Exma. is the abbreviation of Excelentíssimo / Excelentíssima ("most excellent"). It is the genre-obligatory form of address to unknown business recipients, and it has several variants depending on the situation:

OpeningContextEquivalent
Exmo. Senhor, / Exma. Senhora,single recipient, formalDear Sir / Dear Madam
Exmos. Senhores,plural, formal (company, department)Dear Sirs / Dear Sirs and Madams
Exmo. Senhor Dr. (sobrenome),addressing a doctor / lawyer by nameDear Dr. X
Exma. Senhora Engenheira (sobrenome),addressing an engineer by nameDear Ms X (engineer)
Caro Senhor, / Cara Senhora,formal but warmerDear Sir / Dear Madam
Caros Senhores,formal but warmer, pluralDear Sirs and Madams
💡
In Portugal, academic and professional titles are a big part of formal address. If you are writing to someone whose profession you know — a lawyer, a doctor, an engineer, an architect — you address them by title: Exmo. Sr. Dr., Exma. Sra. Dra., Exmo. Sr. Eng., Exma. Sra. Arqta. A British or American English writer would just say "Dear Mr. X" regardless of profession; in Portuguese, the title goes first, and using the wrong one (or omitting it when it is expected) is read as rude or careless.

Notice also the address V. Exas. — an abbreviation of Vossas Excelências ("Your Excellencies") — which is used throughout the letter as the formal 2nd-person plural address. This is the most deferential register in Portuguese, reserved for institutions, businesses, and formal authority. For a single recipient, use V. Exa. (Vossa Excelência).

3. The Assunto line

Assunto: Reclamação formal relativa ao contrato n.º 45678321

Subject: Formal complaint relating to contract no. 45678321

Portuguese formal letters include a subject line (Assunto) above the body, much like the subject line of an email. It is typically a noun phrase, short, in title-like register. The nominalisation (Reclamação formal relativa...) is genre-standard — a verb-based title like Reclamar formalmente sobre o contrato would read as too casual.

4. The set-piece opening: Serve a presente para...

Serve a presente para apresentar uma reclamação formal.

The present letter serves to submit a formal complaint.

Serve a presente para + infinitive is one of the canonical letter openings in Portuguese. A presente refers to the letter itself (implied: a presente carta), and the formula signals "the purpose of this letter is...". Other equivalent set-pieces include:

Venho por este meio informar V. Exas. de que...

I hereby inform you that... (literally: I come by this means to inform)

Vimos pela presente solicitar a vossa atenção para...

We hereby request your attention to... (1pl institutional)

Tenho a honra de comunicar a V. Exas. que...

I have the honour to communicate to you that...

Dirijo-me a V. Exas. no sentido de...

I address you in order to... (dirigir-se, reflexive)

These are not paraphrasable. A Portuguese business reader expects one of these openings. Replace them with a direct English-calqued opening — Escrevo para dizer que... ("I am writing to say that...") — and the letter will sound informal, almost impolite. The conventions are the content.

💡
The 1st-person plural vimos pela presente ("we hereby...") is used even when the writer is one person, as long as they are writing in an institutional capacity (on behalf of a company, department, or organisation). A private customer writing on their own behalf uses 1st-person singular venho pela presente or serve a presente para + infinitive. This 1pl/1sg distinction is a register signal in Portuguese letters.

5. The impersonal / institutional voice

Once the letter is under way, Portuguese formal correspondence prefers impersonal constructions over personal ones. The body of our letter uses o serviço tem apresentado falhas rather than o vosso serviço falhou-me; não foi adoptada qualquer medida rather than vocês não tomaram nenhuma medida; foram apresentadas três reclamações rather than eu reclamei três vezes.

O serviço tem apresentado falhas reiteradas.

The service has been showing repeated failures. (present perfect — continuing pattern)

Apesar de terem sido apresentadas três reclamações anteriores...

Despite three previous complaints having been submitted... (personal infinitive in the passive)

Não foi até à data adoptada qualquer medida eficaz.

No effective measure has been adopted to date.

This impersonal turn has several functions. It distances the complaint from personal grievance, it makes the letter sound institutional and measured, and — critically — it transfers the weight of the action onto the recipient without accusing them directly. Não foi adoptada qualquer medida invites the recipient to correct that state of affairs; vocês não fizeram nada would accuse them.

Note also the pre-AO90 spellings the letter uses: adoptada, adoptar — current AO90-standard PT-PT writes adotada, adotar (dropping the mute p before t). However, formal legal and commercial documents in Portugal still frequently retain the old -pt- spellings, partly out of inertia and partly out of stylistic preference. Similarly, the letter uses facto (AO90 retains -ct- when pronounced, as here) versus fato which in PT-PT means "suit (of clothing)" — a spelling distinction that is still very much alive.

6. The conditional of politeness: agradeceria que... se pronunciassem

The central request of the letter uses the conditional of politeness with an imperfect subjunctive:

Agradeceria que V. Exas. se pronunciassem sobre o assunto.

I would be grateful if you would comment on the matter.

This pattern — conditional + que + imperfect subjunctive — is the softest, most deferential way to request action in formal Portuguese. It is not "I would be grateful if" (a hypothetical); it is a ritualised polite demand. The conditional agradeceria is softer than the present agradeço; the imperfect subjunctive se pronunciassem is softer than the present subjunctive se pronunciem. Stack both together and you have the maximum-politeness shape.

Other conditional-of-politeness formulas:

Seria grato se V. Exas. pudessem providenciar uma resposta célere.

I would be grateful if you could provide a prompt response.

Gostaria que fosse feita uma revisão do contrato.

I would like the contract to be reviewed.

Agradeceria que nos fosse enviada documentação complementar.

I would be grateful if additional documentation could be sent to us.

💡
The conditional is Portuguese's politeness marker par excellence. Agradeço = "I thank". Agradeceria = "I would thank / I would be grateful". The conditional shift is not about hypothetical scenarios — it is about softening a request. The more formal the context, the more conditionals you stack.

7. The subjunctive in request and hypothetical clauses

The letter uses several subjunctives:

Agradeceria que V. Exas. se pronunciassem...

I would be grateful if you would respond... (imperfect subjunctive after agradeceria que)

Caso tal não se verifique, ver-me-ei obrigada a apresentar queixa.

Should this not occur, I will be obliged to submit a complaint. (present subjunctive after caso)

Solicitamos que nos seja enviada a documentação.

We request that the documentation be sent to us. (present subjunctive after solicitamos que)

The rule is that verbs of request and will (agradecer que, solicitar que, pedir que, rogar que, requerer que) take subjunctive. In the present this is the present subjunctive; in the conditional it becomes the imperfect subjunctive. Similarly, caso ("should / in case / if") takes the present subjunctive, and is itself a more formal alternative to se in formal letters.

8. Mesoclisis in a letter: ver-me-ei

The letter contains one mesoclitic construction:

Ver-me-ei obrigada a apresentar queixa junto da ANACOM.

I will be obliged to submit a complaint to ANACOM.

Ver-me-ei = future indicative verei + reflexive me = ver-me-ei. The pronoun slips inside the future tense because there is no proclisis trigger in the clause. In spoken PT-PT this would almost always be vou ver-me obrigada or vejo-me obrigadamesoclisis is a marker of the written formal register.

Notice the adjective agreement: ver-me-ei obrigada — feminine, because the writer (Ana Maria) is female. If the writer were male, it would be ver-me-ei obrigado. Portuguese adjective agreement is strict and does not forgive gender slips even in formal correspondence.

9. The junto da ANACOM construction

Apresentar queixa junto da ANACOM.

To submit a complaint to ANACOM (the regulator).

Junto de ("to / before / with [an institution]") is a formal preposition meaning "to a body or authority". It is used when talking about lodging complaints, filing requests, or making representations to an institution. Apresentar queixa junto da ANACOM (the Portuguese telecoms regulator) is standard; a Brazilian speaker would often say contra a ANACOM or na ANACOM, but in formal PT-PT junto de is the register-appropriate preposition.

10. The closing formulas

Agradecendo desde já a atenção dispensada, e ficando a aguardar a vossa resposta, subscrevo-me,

Thanking you in advance for the attention shown, and remaining in wait of your response, I subscribe myself,

Com os melhores cumprimentos,

With best regards,

Portuguese formal letters close with a ritualised two-part formula: a gerund-heavy acknowledgement followed by a sign-off line. The acknowledgement typically uses gerunds to string together multiple polite actions: agradecendo, ficando a aguardar, apresentando, colocando-me ao vosso dispor. The sign-off line is one of a closed set:

ClosingRegister
Com os melhores cumprimentos,standard formal (safest default)
Atenciosamente,formal, slightly cooler
Cordialmente,formal, slightly warmer
Com elevada consideração,very formal (to authorities)
Apresento os meus melhores cumprimentos,traditional, elaborate
Sem outro assunto de momento,neutral commercial closing

The most neutral sign-off in modern Portuguese business correspondence is Com os melhores cumprimentos. For emails to colleagues or known contacts, this can be shortened to Cumprimentos, softened to Os melhores cumprimentos, or warmed up to Um abraço if there is already a professional relationship. Atenciosamente is common in Brazilian Portuguese and is understood in PT-PT but not the default there.

💡
The closing formula is a genre signal, not a sentiment. Writing Sinceros cumprimentos (a direct calque of "Sincerely") sounds slightly off in Portuguese — the fixed formula is Com os melhores cumprimentos. Memorise the set-pieces; do not translate from English.

Note also the verb subscrevo-me, a traditional closing verb meaning "I subscribe myself / I sign myself". Modern letters sometimes omit it; older and more formal correspondence includes it. Subscrevo-me + closing formula is the full ceremonial shape.

11. The Face ao exposto connector

Face ao exposto, agradeceria que V. Exas. se pronunciassem.

In view of the above, I would be grateful if you would respond.

Face ao exposto ("in view of what has been set out") is a classic letter-writing transitional phrase. It signals: now that I have laid out the facts, here is what I am asking you to do. Other equivalent transitional phrases:

  • Nestes termos — "on these terms / accordingly"
  • Pelo exposto — "from the above"
  • Em face do exposto — fuller version of face ao exposto
  • Em virtude do acima exposto — even more formal
  • Nos termos da legislação aplicável — "under applicable law" (legal formula)

Things to notice

The verb tenses of a formal letter

A formal Portuguese letter typically deploys a specific set of tenses:

  1. Present perfect (tem apresentado) — to describe an ongoing problem
  2. Preterite (celebrado no passado dia, apresentadas três reclamações) — for completed historical events (participial passive)
  3. Present subjunctive (caso tal não se verifique) — in hypothetical clauses
  4. Imperfect subjunctive (se pronunciassem) — after conditional verbs of request
  5. Conditional (agradeceria, seria grato) — for politeness
  6. Future (ver-me-ei obrigada) — for stated consequences, often mesoclitic
  7. Gerund (agradecendo, ficando) — in the closing formula

Learning the functions of each tense in the letter genre is more useful than memorising the formulas blindly. Once you know that the conditional + que + imperfect subjunctive is "the polite request shape", you can produce it spontaneously.

The density of nominalisations

Read the letter again and count the noun phrases: reclamação formal, interrupções diárias, velocidades substancialmente inferiores, total indisponibilidade, medidas eficazes, resolução do problema, reposição do serviço, prazo máximo, rescisão do contrato, penalização, legislação aplicável. Nominalisation carries most of the meaning. Verbs are often delegated to auxiliaries (apresentar uma reclamação rather than reclamar; proceder à rescisão rather than rescindir). This is the nominal register that Portuguese formal letters require.

The address system layering

The letter stacks multiple forms of address:

  • V. Exas. as direct address throughout
  • Exmos. Senhores as the opening
  • vossa (possessive of vós) in a vossa resposta
  • 3rd-person-plural verb agreement (se pronunciassem, V. Exas. pudessem)
  • nominal closing formula (Com os melhores cumprimentos — impersonal, no finite verb)

Note that the vossa form is used in PT-PT formal letters even though vós has disappeared from speech — it survives exclusively in this ceremonial register. A Portuguese speaker will never say vós in conversation but will write a vossa resposta in a letter without thinking about it.

Common mistakes

❌ Caro João,

Too informal for a letter to an unknown company or authority.

✅ Exmos. Senhores,

Dear Sirs (standard formal opening)

❌ Eu escrevo para reclamar sobre o serviço.

Direct English calque — lacks the formal opening formula.

✅ Serve a presente para apresentar uma reclamação formal.

The present letter serves to submit a formal complaint.

❌ Eu queria que vocês respondam em dez dias.

Mixed tense shift (imperfect + present subjunctive) and informal vocês — wrong register.

✅ Agradeceria que V. Exas. se pronunciassem no prazo de dez dias.

I would be grateful if you would respond within ten days.

❌ Obrigada pela atenção, beijinhos.

Informal sign-off in a formal letter — disastrous.

✅ Agradecendo desde já a atenção dispensada, subscrevo-me, Com os melhores cumprimentos,

Thanking in advance for the attention shown, I subscribe myself, With best regards,

❌ Se vocês não responderem, eu vou à ANACOM.

Informal register, direct 2nd-person-plural, future with ir — all wrong for this genre.

✅ Caso tal não se verifique, ver-me-ei obrigada a apresentar queixa junto da ANACOM.

Should this not occur, I will be obliged to submit a complaint to ANACOM.

❌ Sincero, Ana.

Direct translation of 'Sincerely, Ana' — not a real Portuguese closing.

✅ Com os melhores cumprimentos, Ana Maria Figueiredo Cardoso

With best regards, Ana Maria Figueiredo Cardoso

Key takeaways

💡
Formal Portuguese letters are genre-driven. The opening (Exmos. Senhores), the set-piece connector (Serve a presente para..., Venho por este meio..., Face ao exposto...), the conditional of politeness (agradeceria que... se pronunciassem), and the closing (Com os melhores cumprimentos) are non-negotiable. Do not paraphrase them — memorise them as chunks.
💡
The conditional + imperfect subjunctive pattern (agradeceria que V. Exas. se pronunciassem) is the maximum-politeness request shape in formal PT-PT. It replaces direct commands and blunt requests in any context where you are writing to a person in authority or an institution.
💡
The address system in formal letters uses V. Exas. (plural) or V. Exa. (singular) — abbreviations of Vossas Excelências / Vossa Excelência. Combined with vossa possessive and 3rd-person-plural verbs (vossa resposta, V. Exas. pudessem), this creates the ceremonial impersonal voice of business correspondence.

For deeper practice, see Formal Register, Conditional of Politeness, Formal Address Pronouns, and the less formal Holiday Letter (A2) for contrast.
