Free.ai Business Email Writer is a B2B email template library — 12 ready-to-go templates (sales proposal, invoice follow-up, RFP response, NDA cover, partnership ask, vendor negotiation, quote request, contract renewal, termination, project kickoff, status update, B2B introduction) that turn a few specifics into a subject + body ready to send.
Write Email is tone-heavy — friendly, apologetic, casual, persuasive. Business Email is template-heavy — every output follows established B2B conventions (formal subjects, placeholder-based pricing/dates, signature blocks, attachment lines). Pick this one for invoices, RFPs, NDAs, and vendor contracts. Pick /write/email/ for recruiting, thank-you notes, and customer replies.
Grammarly Business ($15/seat/month) edits existing drafts, does not generate from scratch. Lavender ($29/month) focuses on cold-outreach personalization. Regie.ai charges $59+/month for sequence generation. Free.ai gives you the core business-email templates for free, with premium AI models available per-use for tighter prose. No seats, no monthly commitment.
Yes — Qwen 3 30B on our GPUs, about 200-400 tokens per email inside the daily pool. Premium models (Claude Sonnet, GPT-5) cost more per email but produce the tightest corporate voice when you are emailing a Fortune 500 counter-party.
Yes — the system prompt instructs the model to use [amount], [date], [invoice #], [contract clause] rather than invent. This protects you from sending an invoice follow-up with a fabricated invoice number. Search/replace before sending.
Yes — fill in the "Your name + title" field and the model closes with your chosen sign-off ("Best regards, Jane Park, Head of Partnerships"). Combine with the attachments/CC toggle for a polished corporate feel.
No — first email is free, no email required, no credit card. Sign up for a free account for 10,000 tokens and 7-day share links (24h anonymous).
Yes — the "Open in mail app" button builds a mailto: URL and launches your default mail client with subject + body pre-filled. Long emails (>1900 chars) warn about mailto truncation; in those cases copy the body manually.
Three levels: Executive (maximally formal — "Dear Mr. Chen", full titles), Standard (typical B2B — "Hi Sarah", professional but warm), Collegial (peer — first names, conversational). Pick based on how senior the recipient is and how new the relationship is.
Yes — type your specifics in Japanese or German and the model generates locally appropriate business conventions (keigo register in Japanese, Sie-form in German, formal "usted" in Spanish). All 99 Free.ai languages supported.
For subject-line A/B testing, use our general /write/email/ tool which includes an "Include 3 alt subject lines" checkbox. Business Email focuses on single ready-to-send output; swap templates if you need more iteration.
Yes — POST to /v1/chat/ with the template-specific system prompt (available in the template source). Useful for billing systems that need to fire automated invoice chasers at 15, 30, 45 days past due. Bearer auth, monthly limits. Docs at /api/.
