Building Emails
Fonts
Use web-safe fonts for consistency across email clients.
Select Inherit font to apply your brand’s default typography. This option isn’t a separate font—it's a placeholder that automatically adopts the default font family, size, and color set in your brand settings.
Limit font choices to improve load time.
Recommended font sizes:
12–16 pt for mobile
16–20 pt for desktop
Images
File Size: Keep all images under 1MB total.
Formats Supported: GIF, JPG, PNG.
Alt Text: Always include for accessibility and fallback visibility.
Animated GIFs: Keep small; ensure first frame displays well.
Dimensions: Use double-width images for retina (e.g., 1200px for 600px layout).
PPI: Minimum 72 recommended.
Videos: Link externally; use a static screenshot with play icon.
Placeholder Images
Email File Size
Keep under 102KB to avoid Gmail clipping.
Reduce the number of rows unless different layouts are needed.
Layout and Design Tips
Padding
Use consistent padding across all layout sections.
Apply the same padding on all sides for mobile optimization.
Global Settings vs. Pop-Up Editor
Use Global Settings for consistent styling across modules.
Use the Pop-Up Editor for individual tweaks.
✅ Best practice: Favor global settings. Use Pop-Up Editor only for specific overrides.
Links
Add links to emails, phone numbers, and addresses to avoid auto-formatting by email clients.
Use link attributes to style your links for better control.
Special Links
Your email should include:
An Unsubscribe link that is easy to find and use.
Consider adding:
Forward to a Friend link
View as Webpage link
Use “special links” in Knak by editing your merge tag, checking “special link,” and applying the link in the Pop-Up Editor.
Mobile Optimization
Use Do Not Stack for fixed layouts.
Adjust stacking order if needed.
Use hide-on-mobile/desktop toggles for alternate versions.
⚠️ Keep duplicate content minimal to reduce file size.
Working With Modules
Modules
Categorize First: Set categories before creating new modules.
Clone for Consistency: Build once and duplicate for reuse.
Custom Themes
Build themes using reusable modules.
Use Apply to Themes to push updates across themes.
Publishing Modules
Save work in progress as Unpublished Changes.
To publish a module:
Select Actions at the top right of the module builder then press publish
Or click Unpublished Changes → Confirm and Publish
Assign modules to all brands or specific ones using the dropdown menu
💡 Reminder: If you're actively working on an email or landing page and publish module updates in another tab, refresh the asset to ensure the latest module version is loaded. After refreshing, check the Optimize tab and update any Out of Date Modules to apply the latest changes.
