Formatting tips: URLs, emails, phone numbers
URLs
each URL must start with 'http://' or 'https://'.
Emails
Confluence supports advanced mailto: link formatting to prepopulate an email when the link is clicked. The email is normally created in the desktop client as it is the default on most computers.
must start with 'mailto:' followed by the email
Multiple emails
When a user clicks on the link it prepopulates the To field with multiple emails.
CC and/or BCC
To add CC and BCC to your email, use the cc or bcc parameter.
mailto:email@example.com?cc=secondemail@example.com, anotheremail@example.com, &bcc=lastemail@example.com
Subject line
Include a prepopulated subject line.
mailto:email@example.com?subject=Subject line text
Body text
Include a prepopulated body text.
mailto:email@example.com?body=Body text
Combine parameters
mailto:email@example.com?cc=secondemail@example.com, anotheremail@example.com, &bcc=lastemail@example.com&subject=Mail from our Website&body=Some body text here
Phone numbers
The ‘tel:’ format is not fully supported.
Within same country, Confluence native
‘tel:’ links can only have numbers. Therefore, a number only works for callers from within the same country and if the number is written in the URL exactly as if dialing within the country. Example in North America ‘tel:2025557777'.
The 'tel:+' for international calling does not work natively in Confluence.
International calling, need an app
The only way to use 'tel:+' is to get an HTML macro app from the Atlassian Marketplace so that you can use HTML on the page. Here is an example as to what you could add inside such a macro to make the phone number usable for users in any country:
<a href="tel:+441234567890“>Call us</a>
Atlassian does not have short term plans to fully support the tel: standard (see closed feature request).
