To edit any contact:
Open the People page of your Reply account.
Use search if you have a lot of contacts.
Click on the contact to open the contact sidebar.
Click Save after you have finished editing the contact.
Note: you can paste a hyperlink in any contact field. If a link was added without any extra text in the field (for example LinkedIn, Company name, or any custom field), it can be opened in another browser tab using the CTRL + Click hotkeys on Win or CMD + Click on Mac.
