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 flag in ravi email compose/reply/forward accepts HTML. Always use semantic tags — never pass plain text.
Note: --subject is only used with ravi email compose. Reply and forward commands auto-derive the subject from the original message (prepending Re: or Fwd:).
Do this:
<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:
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 identity list --json | jq -r '.[0].name'
Recommended Template
Copy-paste starting point for most emails:
NAME=$(ravi identity list --json | jq -r '.[0].name')
ravi email compose \
--to "recipient@example.com" \
--subject "Specific subject under 60 chars" \
--body "<p>Hi Alex,</p>
<p>I'm reaching out about [specific topic]. [One sentence of context.]</p>
<p>[Core message — what you need, what you're sharing, or what you're asking.]</p>
<ul>
<li>[Key point or action item]</li>
<li>[Key point or action item]</li>
</ul>
<p>[Clear next step — what should the recipient do?]</p>
<p>Best,<br>$NAME</p>" --json
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 |
