Twig filter: how to set a custom link label?

Problem/Motivation

Using the field formater, you can set a custom link label to be used instead of the email address.

In twig, using {{ 'terry.jones@spam.com'|obfuscateMail }} renders as <a href="mailto:terry.jones@spam.com">terry.jones@spam.com</a>

Is there a way to alter the link label in order to render as <a href="mailto:terry.jones@spam.com">Send mail</a> while keeping the email address obfuscated?
