Enhanced HTML email formatting for gog CLI with ready-to-use templates.

How to Send HTML Emails

ALWAYS use this exact workflow:

1. Read the appropriate template file from workspace/skills/gog-html-email/templates/
2. Replace placeholders using sed commands
3. Send via gog gmail send --body-html

Example:

TEMPLATE=$(cat workspace/skills/gog-html-email/templates/basic.html)
HTML=$(echo "$TEMPLATE" | sed 's/\[NAME\]/John/g' | sed 's/\[MESSAGE\]/Your message here/g' | sed 's/\[SIGNATURE\]/Your Name/g')
gog gmail send --to recipient@example.com --subject "Subject" --body-html "$HTML"

For multi-paragraph messages:

TEMPLATE=$(cat workspace/skills/gog-html-email/templates/basic.html)
# Replace [MESSAGE] with multiple <p> tags for proper spacing
MESSAGE='<p style="margin: 0 0 16px 0;">First paragraph.</p><p style="margin: 0 0 16px 0;">Second paragraph.</p><p style="margin: 0 0 16px 0;">Third paragraph.</p>'
HTML=$(echo "$TEMPLATE" | sed "s|\[MESSAGE\]|$MESSAGE|g" | sed 's/\[NAME\]/John/g' | sed 's/\[SIGNATURE\]/Your Name/g')
gog gmail send --to recipient@example.com --subject "Subject" --body-html "$HTML"

DO NOT:

• Manually construct HTML strings
• Use heredocs or multi-line strings
• Include literal \n characters in HTML
• Put multiple paragraphs in a single <p> tag

Best Practices

1. Use template files - All templates are pre-formatted and tested
2. Single-line HTML - Templates are already single-line to avoid formatting issues
3. Inline CSS - All templates use inline styles for email client compatibility
4. Max Width - Templates are set to 600px for optimal viewing
5. System Fonts - Templates use -apple-system, BlinkMacSystemFont, Segoe UI, Roboto for best rendering
6. Test First - Send to yourself before sending to recipients
7. Replace all placeholders - Make sure to replace all [PLACEHOLDER] values with actual content

Customizing Templates

You can customize template colors, fonts, and styling by adding additional sed commands to replace CSS values.

Common Customizations

Change gradient colors:

TEMPLATE=$(cat workspace/skills/gog-html-email/templates/birthday.html)
# Replace pink gradient with blue gradient
HTML=$(echo "$TEMPLATE" | sed 's/#f093fb/#4facfe/g' | sed 's/#f5576c/#00f2fe/g')
# Then replace placeholders and send
HTML=$(echo "$HTML" | sed 's/\[NAME\]/John/g' | sed 's/\[MESSAGE\]/Your message/g' | sed 's/\[SIGNATURE\]/Your Name/g')
gog gmail send --to recipient@example.com --subject "Subject" --body-html "$HTML"

Change primary color:

TEMPLATE=$(cat workspace/skills/gog-html-email/templates/basic.html)
# Change all blue (#007bff) to purple (#667eea)
HTML=$(echo "$TEMPLATE" | sed 's/#007bff/#667eea/g')
HTML=$(echo "$HTML" | sed 's/\[NAME\]/John/g' | sed 's/\[MESSAGE\]/Your message/g' | sed 's/\[SIGNATURE\]/Your Name/g')
gog gmail send --to recipient@example.com --subject "Subject" --body-html "$HTML"

Change background color:

TEMPLATE=$(cat workspace/skills/gog-html-email/templates/highlight.html)
# Change highlight box from light gray to light blue
HTML=$(echo "$TEMPLATE" | sed 's/#f8f9fa/#e3f2fd/g')
HTML=$(echo "$HTML" | sed 's/\[NAME\]/John/g' | sed 's/\[MESSAGE\]/Your message/g' | sed 's/\[SIGNATURE\]/Your Name/g')
gog gmail send --to recipient@example.com --subject "Subject" --body-html "$HTML"

Change font size:

TEMPLATE=$(cat workspace/skills/gog-html-email/templates/basic.html)
# Make heading larger (36px to 48px)
HTML=$(echo "$TEMPLATE" | sed 's/font-size: 36px/font-size: 48px/g')
HTML=$(echo "$HTML" | sed 's/\[NAME\]/John/g' | sed 's/\[MESSAGE\]/Your message/g' | sed 's/\[SIGNATURE\]/Your Name/g')
gog gmail send --to recipient@example.com --subject "Subject" --body-html "$HTML"

Change layout alignment (left-align instead of center):

TEMPLATE=$(cat workspace/skills/gog-html-email/templates/basic.html)
# Remove centering: change "margin: 0 auto" to "margin: 0"
HTML=$(echo "$TEMPLATE" | sed 's/margin: 0 auto/margin: 0/g')
HTML=$(echo "$HTML" | sed 's/\[NAME\]/John/g' | sed 's/\[MESSAGE\]/Your message/g' | sed 's/\[SIGNATURE\]/Your Name/g')

Notes

• Templates are single-line HTML to prevent formatting issues
• For complex layouts (tables, multiple sections), create a custom template file
• Always test HTML emails in multiple clients (Gmail, Outlook, Apple Mail)
• Use plain text (--body) for simple messages without formatting needs
