E-Mail ist immer noch die wirkungsvollste Schreibarbeit, die die meisten Menschen leisten. Vertrieb, Support, Recruiting, Fundraising — alles hängt an einer klaren, gut aufgebauten E-Mail. Dieser kostenlose KI-E-Mail-Generator entwirft eine komplette E-Mail aus einem Einzeiler: Wähle den Typ (Kaltakquise, Follow-up, internes Update, Antwort, Entschuldigung), gib Ziel und Empfänger an und erhalte in unter 10 Sekunden einen ausgefeilten Entwurf. Ohne Anmeldung, unbegrenzte Generierungen.
When AI email writing actually helps (and when it hurts)
Use AI to break the blank-page paralysis: the first draft of a tough email — performance feedback, customer escalation, fundraising ask — is usually 80% structure and 20% your specific facts. The AI handles the structure in 5 seconds; you spend the saved time on the 20% that matters.
Don't use AI for short, conversational replies where the AI's polish reads as oddly formal. A two-sentence response to a coworker doesn't need rewriting. Save the tool for emails over 100 words, emails with a clear desired outcome, and emails you'd otherwise procrastinate on writing.
Email types the generator handles well
Eight types are templated and tested: (1) Cold outreach (sales, fundraising, networking) — short, specific, one ask. (2) Follow-ups (post-meeting, post-pitch, post-call) — reference the prior touch, restate value, propose next step. (3) Internal updates (project status, weekly recap) — structure: outcome, what's blocked, what's next. (4) Customer support replies — empathetic, solution-first, clear timeline. (5) Apologies — acknowledge, take responsibility, fix, prevent. (6) Decline / rejection emails — kind, brief, no false hope. (7) Performance feedback — specific behavior, impact, ask. (8) Fundraising / partnership pitches — problem, solution, traction, ask.
Pick the type from the dropdown — the AI tunes tone, length, and structure accordingly.
Subject lines that get opened in 2026
Subject line open rates have dropped industry-wide as inboxes get more crowded. Three patterns still hit above-average: question subjects naming the recipient's situation ('Scaling support past 1,000 tickets?'), specific outcome promises ('a 47% lift on your homepage'), and explicit-context names ('via [mutual]', 'follow-up to [prior thread]').
Generic subjects ('Touching base', 'Quick question', 'Following up') open at 8-12% in 2026 — half what they did in 2020. Inbox filters and recipients both ignore them. The generator outputs 3-5 subject line variants per email; pick the most specific one.
Email length: shorter than you think
Best-converting cold emails in 2026 land between 75-125 words. Internal updates: 150-250 words. Apologies: under 100 words (long apologies feel performative). Customer replies: as long as needed for the answer, but lead with the resolution.
The single biggest mistake in AI-generated emails is over-explanation. Default AI output trends toward 200+ words for everything. The generator caps lengths per type and flags drafts that exceed the recommended range — most users cut another 20% after the AI's first pass.
Deliverability matters more than copy
Even perfectly written emails fail if they land in spam. For any volume above 10 emails/day from a new inbox: set up SPF, DKIM, and DMARC records on your domain (one-time, every email host has guides). For volume above 50/day: warm up the inbox for 2-4 weeks with services like Mailwarm or Lemwarm before scaling. For volume above 200/day: rotate across 2-3 inboxes, cap each at 50/day, and monitor reply + bounce rates weekly.
Fix deliverability before optimizing copy. A perfectly written email in spam = an unread email.
