“Blast” Object

Within any Zephyr context, the blast object contains a number of useful pieces of data about the current campaign email message. This object is useful for populating dynamic sections of an email based on items such as the sending list.

Here is a sample message object:

{
  "id" : 123456 ,
  "name" : "Daily Email 08-01-2017" ,
  "list" : "Daily Newsletter" ,
  "suppress_list" : "180 Day Non Openers" ,
  "from_email" : "example@sailthru.com"}

Field	Type	Description
id	integer	The blast/campaign ID
name	string	The name of the campaign
list	string	The target list for sending
suppress_list	string	Any list(s) being suppressed from the campaign
from_email	string	The “from” email address of the campaign

This can be useful for creating a dynamic, list-level optdown from the campaign (provided that the campaign was sent to a Natural List) by appending the {blast.list} value as a query parameter, like so:

<p><small>If you believe this has been sent to you in error, please safely <a href="{optout_confirm_url}&list={blast.list}">unsubscribe</a>.</small></p>  

Then on your optout page:

{if list}
<p>Click here to opt out of {list} emails</p>
<form action="" method="post">
<input type="hidden" name ="lists[{list}]" value="0" />
<input name="action" value="Optout" type="submit" />
</form>
<br/>
{/if}

This section will check if there is a query parameter called “list”, and if so, dynamically populate the list name from which the user will be able to remove themself.
