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.

Fix

Wrap each phone number in an anchor tag: <a href="tel:+15551234567">+1 (555) 123-4567</a>. Wrap each email in: <a href="mailto:contact@example.com">contact@example.com</a>. Format tel: values using E.164 (+[country][number]) without spaces.
