Email send direct

Email Send Direct

Send a single email via Gmail API from CLI

When to use

• "write an email to X"
• "send email to Y"
• "reply to the email"
• Any single email sending (not mass campaign)

IMPORTANT: Confirmation rule

ALWAYS first --dry-run, show preview to the user, and only after "yes" send without --dry-run.

Composing Guidelines

Before writing a single word:

1. Read the full thread — inbox AND sent, not just the latest message. Use email-read skill to pull last 3-5 days of correspondence with this contact.
2. Check CRM — read leads.csv and people.csv for context: deal stage, last activity, relationship notes. The email must reflect where we actually are, not where we were a week ago.
3. Identify what they asked — list every question or request from their last message. Each one must be answered.

Writing rules:

• Answer their questions first. Don't open with pleasantries or context-setting. If they asked "can you invoice monthly?" — start with "Yes, we'll submit monthly invoices."
• Match the thread tone. If the conversation is casual ("Hey Ivan"), reply casual. If formal ("Dear Mr. Pasichnyk"), reply formal. Mirror their level.
• No bot language. Never write: "Please find attached", "I hope this email finds you well", "As per our conversation", "Don't hesitate to reach out". Write like a human.
• No unnecessary bullet points or formatting. Business emails are paragraphs. Use bullets only when listing 3+ distinct items that genuinely benefit from a list.
• Reference shared context. Use "as discussed", "as you mentioned", "following up on our call" — shows you're in the conversation, not generating from a template.
• Keep it short. 3-5 sentences for a reply. 2-3 short paragraphs max for a proposal email. If you need more, the content belongs in an attachment.
• One clear call-to-action. End with exactly one thing you want them to do: review, sign, reply, schedule.

Ivan's voice:

• Short, concrete, direct
• Professional but warm — not stiff, not overly casual
• Says "we" for company actions, "I" for personal commitments
• Signs off: "Best," or "Thanks," — never "Best regards," or "Sincerely,"
• First email in thread: "Hi [Name]," — replies: often no greeting, just jumps in

Anti-patterns (never do these):

Bad	Why	Instead
"Please find attached the proposal"	Corporate robot	"Proposal is attached" or "Attached is the proposal we discussed"
Bullet-point summary of what's attached	They can read it themselves	One sentence saying what it is
Repeating info they already know	Wastes their time	Reference it briefly, move forward
"Let me know if you have any questions"	Empty filler	Specific CTA: "Let me know if the terms work"
Long intro before answering their question	Buries the answer	Answer first, context after

Workflow for Claude

1. Prepare the email text
2. Run with --dry-run
3. Show preview to the user
4. After confirmation -- run WITHOUT --dry-run
5. Script automatically verifies sending (labels, snippet)
