# Tel & Mailto Links

On mobile devices, tel: and mailto: links trigger the native phone dialer and email client with one tap; plain-text contact info forces copy-paste and measurably reduces contact conversion rates.

## Quick Reference

- Wrap phone numbers in `<a href="tel:+15551234567">` for click-to-call on mobile devices
- Wrap email addresses in `<a href="mailto:contact@example.com">` for one-click email compose
- Use E.164 format for `tel:` links: `+` followed by country code and number, no spaces or dashes
- Plain text phone numbers and emails require users to copy-paste — a UX and conversion friction point

## Check

Scan the HTML for phone numbers (patterns like `\+?[0-9\s\-().]{7,}`) and email addresses (`[\w.-]+@[\w.-]+\.[a-z]{2,}`). Verify that phone numbers are wrapped in `<a href="tel:...">` and emails in `<a href="mailto:...">`. Flag any that appear as plain text.
