Make phone and email links hand off predictably

What to change

Ask the supplier to verify the actual destination and device handoff for each telephone and email action.

A worked example

Illustrative example

A visitor choosing Email reception opens a draft addressed to the displayed reception contact, while someone without a mail app can still copy the address.

How to check the result

Accept when the handoff matches the visible promise and practical contact details remain available independently of the external application.

A mistake to avoid

A successful tap that opens an app is not proof that the destination inside that app is correct.

Your action checklist

Use these checks to prepare a discussion with your team or supplier. Tick a check when you have recorded the decision or evidence, rather than when a feature has simply been promised.

Decisions to recordOn a phone, activate the telephone link in a test review and inspect the number presented before initiating any call. Compare it with the visible number.Activate the email link and inspect the addressed recipient and any prefilled text without sending. Ask the supplier to check encoded characters and spacing.Repeat on desktop with and without a configured mail application where practical. The displayed contact information should remain usable if automatic handoff is unavailable.
