You can copy and paste the following code into the Email Reply Theme to make your emails look like they are sent from gmail.

1. Desk.com gmail style email reply template.html

{% assign emails = case.emails %}
{% assign threadlength = emails.size|minus:1 %}  
{% for email in emails reversed %}
 
{% if forloop.first %}
 
{{email.new_html}}
 
{% if email.agent %}
{% if email.agent.signature %}
<div style="margin-top:10px;"> {{email.agent.signature | newline_to_br}}</div>
{% else %}
<p>
  --<br />
  {{email.agent.name_public}}<br />
</p>
{% endif %}
{% endif %}
 
{% else %}
 
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
  On {{email.created_at | in_time_zone: site.timezone | date: "%b %d, %Y”}} at {{email.created_at | in_time_zone: site.timezone | date: "%I:%M%p %Z"}} {{email.from}} &lt;{{email.from_address}}&gt; wrote:<br/><br />
 
{{email.new_html}}
 
{% if email.agent %}
{% if email.agent.signature %}
<div style="margin-top:10px;"> {{email.agent.signature | newline_to_br}}</div>
{% else %}
<p>
  --<br />
  {{email.agent.name_public}}<br />
</p>
{% endif %}
{% endif %}
 
{% endif %}
  
  <br />
 
{% endfor %}
{% for i in (1..threadlength) %} {{ '</blockquote>' }} {% endfor %}

2. Desk.com gmail style email reply template.txt

{% assign emails = case.emails %}{% for email in emails reversed %}
{% unless forloop.first %}
On {{email.send_at | in_time_zone: site.timezone | date: "%b %d, %Y"}} at {{email.send_at | in_time_zone: site.timezone | date: "%I:%M%p %Z"}}, {% if email.agent %}{{email.agent.name_public}} {% else %}{% if customer.id == email.from_customer.id %}{{customer.first_name}} <{{ customer.email }}>{% else %}{{email.from_customer.first_name}} <{{ email.from_customer.email }}>{% endif %}{% endif %}  wrote:
{% endunless %}
{{email.new_text}}
{% if email.agent %}
--
{% if email.agent.signature %}{{email.agent.signature | strip_html }}{%else%}{{email.agent.name_public}}{% endif %}
{% endif %}{% endfor %}

This is a nice simple template, thanks for sharing.

I would LOVE to see the default System Notification Theme be made into an Email Reply Theme, if any of you nice WoW people could be so kind :)

Agreed. Would be awesome if this was a baked in option. I tested with replies to Yahoo and the formatting does not match and the links do not work properly.

It looks like Desk still enforces their own template around these custom themes, adding a visible line above the response body of the email.

See this email source snippet using the plaintext theme from above:

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: Quoted-printable
X-Mailer: Desk.com Support Platform
