About

SUPERCHARGE GMAIL WITHOUT SPENDING $30/MONTH 

Get all the productivity features in Gmail without the hefty price tag and save $360/year. 

⚡ WHY CMDK (formerly SIMPLEHUMAN)?

Gmail feels slow and clunky. Premium email apps charge a premium of $30 to $40/month. CMDK bridges the gap by adding 25+ powerful keyboard shortcuts, a command bar, and smart features that make Gmail feel like a premium email client without a bleeding monthly subscription.

✨ TOP FEATURES

📬 Read Receipts
Track who opens your emails and when - perfect for sales, vendors, and important messages.

📧 Auto CC/BCC 
Set up rules to automatically CC or BCC email addresses on every email you send. Useful for CRM integrations, executive assistants, or looping in team members or managers. 

✂️ Snippets 
Reusable email templates with smart variables ({first_name}, {date+3d}, {clipboard}). Type ; to insert. Supports rich text and HTML templates. 

📎 Smart Actions
RSVP to calendar invites, open links, download attachments, and unsubscribe - all from the command bar.

💡 Keyboard Nudges
