Three steps, then it runs itself

Connect once. Train your tone. Let replies and calls flow.

1

Connect inbox & phone

Link Gmail, Outlook, Amazon or Shopify, and forward your line to a Twilio number. OAuth — we never see your password.

2

Train your voice

Point us at a few past replies, your FAQ and return policy. RespondThat learns your brand tone and facts.

3

Review & go live

We draft emails and answer calls. You glance and click Send, or flip on auto for routine stuff. Busy? The phone answers itself.

What happens in the engine

The same pipeline enterprise help desks use — at a fraction of the cost, tuned for sellers. Email or phone, one engine.

Everything a busy seller needs

No help-desk degree required.

🌍

Multilingual

Native Spanish, Brazilian Portuguese, English, French, German. A São Paulo buyer gets PT-BR; a Mexico City caller gets ES-MX.

🎙️

Brand voice

Learns your tone from past replies so drafts and spoken answers sound like you, not a robot.

📞

Answers the phone

24/7 inbound call handling. Order status, hours, returns — resolved on the spot, in the caller's language.

📚

Knowledge base

Connect your FAQ, return & shipping policy. Replies and answers cite real facts, not guesses.

📦

Order context

Pulls tracking, status and FBA/FBM detail from Shopify / Amazon into every reply and call.

😟

Sentiment escalation

Angry or legal-sounding messages get flagged and routed to you, never auto-sent or mishandled.

How we compare

The drafting extensions don't send. The help desks are pricey and weak on LATAM.

See how it works
💡 The model: no subscription means zero friction to start. Because our AI runs on cheap Chinese token (DeepSeek V4) and self-hosted voice (CosyVoice), each reply costs us cents — so even at $0.20/email we keep ~79% gross margin. The more you use it, the more value (and revenue) compounds. A business built on per-item usage is worth more than one waiting for signups.

Questions

Will it sound like me or like a robot?

Like you. RespondThat learns your tone from past replies and keeps a consistent brand voice across every language — written and spoken.

Do I really pay nothing until it helps?

Yes. No monthly fee, no subscription. You get 25 free email replies and 10 free call-minutes to try. After that you're charged per reply ($0.20) or per answered minute ($0.10). Nothing until we actually do the work.

Can it really send, or just draft?

Both. Most tools only draft. RespondThat connects your send channel (Aliyun DirectMail, Amazon, Gmail) and sends on your behalf — with your approval, or auto-send for routine questions you whitelist.

What about the phone — does it just take messages?

No. It answers, understands intent, checks your orders/KB, and resolves common questions live using self-hosted voice synthesis. Complex or angry calls get handed to you.

What if the AI gets something wrong?

Guardrails check PII, tone and accuracy before anything sends or speaks. Angry or unusual cases are flagged for you. You can always edit before sending.

Is my customer data safe?

We only process what you open, never train shared models on your data, and filter customer PII out of drafts. Every send and call is logged in your account.

Do I need a developer?

No. Connect with one click via OAuth, point us at your FAQ, forward your line to a Twilio number, and start. Setup takes minutes.

Stop writing the same replies. Stop missing calls.

Connect your inbox and phone line, train your voice, and let RespondThat answer in every language your customers speak — and only pay when it does.
