Email Writing Guide

Write emails that look like they came from a real person — not an AI.

Good email hygiene improves deliverability, avoids spam filters, and gets responses.

Subject Lines

40-60 characters — long subjects get truncated on mobile
Be specific — "Q3 metrics review for Acme project" beats "Update"
No ALL CAPS — spam filters penalize this heavily
Avoid spam triggers — "free", "act now", "limited time", "click here", "urgent", "guaranteed", "no obligation"
Match the tone — casual for teammates, professional for external contacts

HTML Body Structure

The --body argument in ravi email compose accepts HTML. Always use semantic tags — never pass plain text.

Note: --subject is only used with the compose command. Reply and forward commands auto-derive the subject from the original message (prepending Re: or Fwd:).

Do this:

html

<p>Opening line that states the purpose.</p>

<p>Supporting details in a second paragraph.</p>

<ul>
  <li>Key point one</li>
  <li>Key point two</li>
</ul>

<p>Closing with a clear next step or ask.</p>

<p>Best,<br>IDENTITY_NAME</p>

Don't do this:

html

Plain text with no tags at all

Or this:<br><br>Using br chains<br><br>instead of paragraphs

Rules:

Always wrap text in <p> tags
Use <h2> for section headers (not <h1>)
Use <ul>/<li> for lists, not dashes or asterisks
Use <a href="...">descriptive text</a> for links — never bare URLs
No <html>, <head>, or <body> wrapper tags — the email system adds these
No <br> chains — use separate <p> tags instead
Get the identity name with: ravi auth status

Recommended Template

Copy-paste starting point for most emails:

bash

ravi email compose \
  --to "recipient@example.com" \
  --subject "Specific subject under 60 chars" \
  --body "<p>Hi Alex,</p><p>I'm reaching out about [specific topic]. [One sentence of context.]</p><p>[Core message — what you need, what you're sharing, or what you're asking.]</p><ul><li>[Key point or action item]</li><li>[Key point or action item]</li></ul><p>[Clear next step — what should the recipient do?]</p><p>Best,<br>YOUR_NAME</p>"

Tone and Style

First person, active voice — "I'll send the report Monday" not "The report will be sent"
Short paragraphs — 2-3 sentences max per <p> tag
Get to the point — state your purpose in the first sentence
End with an action item — "Can you review by Friday?" not "Let me know your thoughts"
No filler phrases — cut "I hope this email finds you well", "Just wanted to touch base", "Per our previous conversation"
No robotic language — cut "I am writing to inform you", "Please be advised", "Kindly note"
Match the thread tone — if they're casual, be casual. If they're formal, be formal.

Anti-Spam Essentials

These rules help your emails land in the inbox, not spam:

High text-to-HTML ratio — more words, fewer tags. Don't over-format.
No link shorteners — use full URLs. Spam filters distrust bit.ly, t.co, etc.
Max 2-3 links per email — more links = higher spam score
No ALL CAPS — not even for emphasis. Use <strong> instead.
No image-only emails — always include text content
One topic per email — don't cram multiple requests into one message
Don't repeat yourself — saying the same thing in different words triggers spam heuristics

Common Mistakes

Mistake	Why it's bad	Do this instead
Plain text in `--body`	Renders as one blob, no formatting	Wrap everything in `<p>` tags
`<br><br>` chains	Looks spammy, inconsistent spacing	Use separate `<p>` tags
"Dear Sir/Madam"	Outdated, signals mass email	Use the recipient's name or "Hi there"
Wall of text	Nobody reads long emails	Break into 2-3 short paragraphs
"Click here" links	Spam trigger, bad accessibility	`<a href="...">descriptive text</a>`
Empty or vague subject	Low open rates, looks like spam	Be specific: "Invoice #1234 for January"
Excessive HTML styling	High tag-to-text ratio triggers filters	Keep formatting minimal
No signature	Looks impersonal, unprofessional	Sign with identity name
"Sent by AI" disclaimers	Undermines trust, unnecessary	Just write naturally
