DRAFT · 17:35 · IN CATA'S VOICEWHERE IT CAME FROM
Hi Maya,
Thanks for reaching out. Sure, send the partner link over.
1She asked one question. It gets a one-line yes first.
My colleague Bogdan, CC'd here, handles affiliate partnerships across our blogs, so he'll take it from there.
2Bogdan handles partnerships, so he's on the CC and the thread has an owner.
If you're also open to paid placements (reviews, comparisons, listicle inclusions), happy to share what we have.
3The upsell you make. No rate quoted: it never invents a price, a date or a promise.
Thanks

You read, you send
Nothing leaves without you.
The only thing the code can make is a draft. There is no send call in it, and no setting to add one.From the install notes
Lyne runs inside accounts you already own. Mail is read on your Google project and sent to the model on your API key.
Every decision is written to a log with its reason and its cost, so a miss is one search away. Disconnect by revoking one token.

The install
From first call to live. Then it's yours.

The call.We read your sent mail together and build the voice guide: who gets "hey", who gets "Dear", your sign-offs, what you never commit to by email. We tell you if it's a fit.
30 minutes02
Your project, your server, your key.Lyne runs on your own Google Cloud project and your own server, with your own API key. Nothing routes through us.

Why an installTHE DRAFTING TOOLSLYNE
A generic draft from a prompt box. Gmail's own Help me write starts from a blank prompt.Starts from the thread, the sender history and your sent mail. No prompting.
They guess what matters, and the guessing is what creates the manual work.Every "no" is labelled and logged with its reason. You move a sender between the lists.
They file, archive or send on their own.Drafts only. There is no auto-send setting.
$12 to $200 a seat, per month, on their servers, with your mail.A flat install on your own Google project and server. Your mail never leaves your account.
No context: it doesn't know what you agreed on the call.Learns from every reply you send. Notes and docs feed the knowledge file.
Book the call.
30 minutes. We read your inbox together, show you what gets skipped and what gets drafted, and tell you if it's a fit. The call settles the setup fee, the monthly per inbox, and a 3-month term with a written exit.
