Why Spark is Great for HTML Signatures
✅ Full HTML Support
Spark supports rich HTML signatures on all platforms — including mobile, which is rare among email apps.
📱 Mobile HTML
Unlike most mobile email apps, Spark lets you use full HTML signatures on iPhone and Android.
🔄 Cross-Platform Sync
Signatures sync across all your Spark devices automatically. Set up once, use everywhere.
⚡ Spark tip: Use the HTML paste mode for the best results. Design your signature with our Signature Generator, copy the HTML code, and paste it into Spark's HTML editor.
