Simple Process
How to Use the Icons that boost open rates
Match your newsletter's voice
A finance newsletter wants polished restrained icons; a creator newsletter wants warm playful ones. Pick the aesthetic that matches your writing.
Build a consistent section iconography
If your newsletter has recurring sections (this week, recommended, deep dive), generate one icon per section and use it every issue. Visual repetition becomes signal.
Export email-safe formats
Use PNG for compatibility across email clients. Keep file sizes small - many email clients throttle image loads or block them entirely.
That's it. From idea to icon in under a minute.

Newsletter icon sizes that actually render
Email clients are notoriously inconsistent at rendering images. These sizes work across Gmail, Apple Mail, Outlook, Substack, ConvertKit, and Beehiiv.
| Context | Size | Format | Notes |
|---|---|---|---|
| Email header logo | 600px wide (variable height) | PNG with transparency | Email body width is typically 600px. Don't exceed - mobile clients will scale down awkwardly. |
| Section dividers | 600x100 to 600x200 | PNG | Visual breaks between newsletter sections. Should feel decorative, not load-heavy. |
| Inline section icons | 48x48 to 96x96 | PNG | Next to section headers or list items. Keep total newsletter file size under 1MB. |
| Article preview thumbnails | 200x200 to 300x300 | PNG or JPG | Used for linked content within the newsletter. Square aspect ratio renders consistently. |
| Footer / signoff icons | 24x24 to 48x48 | PNG | Social links, unsubscribe area. Must render even when client blocks larger images. |
| Open Graph preview | 1200x630 | JPG or PNG | When subscribers share the email link. Should mirror your blog's OG style. |
