Free SVG Icons for Email Templates

Email icon support is notoriously inconsistent across clients. Gmail strips embedded SVGs, Outlook has limited vector support, and many mobile clients ignore external image references. The safest approach is using simple, inline SVG icons with minimal path complexity — or falling back to well-optimised PNG exports at 2x resolution. This collection curates the packs best suited for email: clean monochrome icons with small file sizes and simple SVG structures that survive email client rendering or convert cleanly to inline images.

Frequently Asked Questions

It depends on the client. Apple Mail and some mobile clients render inline SVG well. Gmail strips SVG tags entirely. For maximum compatibility, export icons as small PNG images and embed them as inline images or use hosted image URLs with alt text fallbacks.

Feather and Lucide produce the cleanest SVGs with minimal path data, making them ideal for PNG export at 2x. Simple Line Icons are also excellent for email because of their thin stroke and low complexity.

Run icons through the SVG Optimizer tool on this site to strip metadata and reduce path complexity. Then export as 2x PNG for email embedding. Keep icon dimensions at 24-32px and use inline width/height attributes for consistent rendering.
