AI Email Studio — FAQ

Everything you need to know about the free email tools.

Are the email tools really free?

Yes. Cold Email, Follow-up, Newsletter and Rewriter are free with no account or credit card, powered by the free Gemini API tier.

Will my emails look like spam?

The tools write short, human, personal emails — the opposite of spammy templates. For cold outreach, always personalize the first line before sending.

Can I use the output commercially?

Yes. Use the emails for your business, sales or clients. Adapt them to your voice and your audience before sending.

Is it good for cold outreach?

Yes — it's built for B2B outreach with high-open-rate subject lines, a clear value proposition and a low-friction CTA. Follow-up emails handle the rest.
