Why Spanish speakers face this differently

Spanish speakers writing English business emails face register problems most generic tools miss: ser/estar conflations leak as «is/are» misuse, false friends ("actual" = «current», not «real») slip through unnoticed, and Spanish-influenced sentence rhythms read as overly formal or stiff. Diglot identifies the Spanish-transfer signature and tunes corrections to English business register — not casual chat, not academic stiffness.

The Diglot workflow for business email writing

  1. 1

    Draft in Spanish or English

    Open Diglot, paste a Spanish draft OR start typing in English. Many Spanish-speaking professionals draft in Spanish (where business etiquette is internalized), then translate to English.

  2. 2

    Translate with business register

    Highlight Spanish paragraph → translate. Diglot routes business-email translation through register-tuned engines — formal but not stilted, polite but not overly deferential.

  3. 3

    L1-aware grammar — Spanish patterns

    Diglot flags ser/estar leak as «is/are» mismatches, false friends (actual, eventually, sensible, library, etc.), gerund overuse from Spanish gerundio, and adjective placement.

  4. 4

    Cowriter for tone polishing

    Cowriter Edit mode lets you select a paragraph + ask «make this more polite without being deferential» or «tighten to 2 sentences». English business emails are shorter than Spanish — Cowriter helps with that pruning.

  5. 5

    Quick send-check

    Before sending: Diglot flags missing greetings («Hi» vs «Dear»), missing sign-offs, and subject-line clarity. These are small but the cost of getting them wrong in business is high.

Spanish → English patterns Diglot catches

Draft (Spanish-influenced)CorrectedWhy
I am actually working in the project.I am currently working on the project.False friend «actually» — Spanish «actualmente» = currently, not English «actually» (which means «in fact»). Pattern: `false-friend-actual-actualmente`.
The meeting is in 3 PM.The meeting is at 3 PM.Preposition transfer — Spanish «a las 3» translates literally to «in 3», but English uses «at» for clock times. Pattern: `preposition-time-at-vs-in`.
I am agree with the proposal.I agree with the proposal.Adding «is» before adjectives that are actually verbs in English — Spanish «estoy de acuerdo» (literally «I am in agreement») leaks as «I am agree». Pattern: `agree-as-adjective`.
For finishing the report, I need more data.To finish the report, I need more data.Spanish «para + infinitive» translates literally as «for + gerund» but English uses «to + infinitive» for purpose. Pattern: `for-gerund-purpose`.

Frequently asked questions

Does Diglot work for Latin American Spanish or only European Spanish?
Both. Our L1 model covers Spanish broadly — most transfer patterns (ser/estar, false friends, prepositions) apply across regional variants. For region-specific terminology in your output, the Glossary feature lets you pin your team's preferred terms (e.g., «computer» = «computadora» in MX, «ordenador» in ES) so they're used consistently.
How does Diglot handle formal vs informal business contexts?
Cowriter Edit mode lets you specify tone: «more polite», «more direct», «more formal», «less formal». English business email register is narrower than Spanish (no «usted» vs «tú» distinction), so Diglot defaults to neutral-professional, then tunes per your request.
What about cover letters and CVs vs business emails — are they different?
Cover letters and CVs are different use cases — we have a dedicated /use-cases/cover-letter-for-arabic-speakers/ guide (and others coming for Spanish soon). Business emails are shorter, more transactional. Cover letters are narrative + self-positioning, requiring different register tuning.
Does Diglot integrate with Gmail or Outlook?
Not yet — Diglot is web-first today (web.diglot.ai). Browser extension shipping Stage 5.1 will surface Diglot directly in Gmail/Outlook compose windows. Google Workspace Add-on (Stage 5.2) adds native Gmail integration. Today, most Spanish-speaking professionals draft in Diglot, then copy-paste to email — friction we're actively closing.
How does the tool handle Spanish business-letter conventions like «Estimado/a» or sign-offs?
It does not translate Spanish conventions literally — that would produce «Esteemed Mr. Garcia, ...» which reads archaic in English. Instead, Diglot maps the Spanish convention to its English business-email equivalent: «Estimado Sr. García» → «Dear Mr. García» (formal first contact) or «Hi Marcos» (subsequent correspondence with someone you know). For sign-offs, «Atentamente» becomes «Best regards» or «Sincerely» depending on whether the relationship is mid-relationship or initial. The tool surfaces the convention choice — formal vs warm — so you adjust for the actual recipient relationship rather than reflexively translating the Spanish formality layer one-to-one.
