Liquid Syntax would allow more customization in emails without using variables

Default values :

{{ contact.first_name || ’Mister’ }}

Conditions :

{{% if contact.email === ‘i_known_you@company.com’ %}} What's up

{{% elseif contact.lang === ‘fr’ %}} Bonjour

{{% elsif contact.lang === ‘en’ %}} Hello

{{% endif }}

Access to user data :

{{% if sender.email === ‘romain@datananas.com’ %}} CTO

{{% elsif sender.email === ‘rcornu@datananas.com’ %}} CMO
