Seed lists

A seed list allows you to test where an email will land across different email clients and devices, as well as see how your campaigns are rendered in different browsers and email clients.

The seed list feature in Blueshift requires you to upload a list of users (for example, internal users) and subsequently use it in a campaign. When the campaign is launched, it sends a copy of the first message to each user in the seed list.

The seed list behavior for different types of campaigns is as follows:

Set up seed lists

1. Follow the same Customer List setup process, but select "Seed list" as the option.
   
2. Associate the Seed list to use with the campaign in the Monitoring section of the Properties tab for the campaign.
    

   

Seed list settings for continuous campaigns 

You can choose the seed list sending behavior you prefer for your continuously sending campaigns (either event-triggered or continuous-segment-triggered campaigns). These settings are available under Campaign Properties -> Monitoring Preferences.

• Select Send to seed list only once if you want to send to the seed list only once per campaign launch.
• Select the Seed list send every time period settings to send the seed list at a set frequency.

As described in the table above, Seed list sends are based on the following conditions:

• Seed list sends are triggered when a message is successfully sent to a customer from the given campaign.
• Seed list send settings are defined in campaign monitoring preferences

Seed list send examples

In all examples, the campaign begins at 2 AM, and the seed list frequency is set to every 6 hours.

• Example 1:
  The first customer message is triggered at 3 AM.
  The seed list is sent at 3 AM, alongside the first message.
• Example 2:
  Messages are triggered at 2 AM and 10 AM (no trigger at 8 AM).
  The seed list is sent at 2 AM and 10 AM; it skips 8 AM because there is no trigger.
• Example 3:
  Messages are triggered at 2 AM and 8 AM.
  The seed list is sent at 2 AM and 8 AM, aligned with a 6-hour frequency.
• Example 4:
  The campaign starts at 2 AM, but no message is triggered at launch.
  It is paused at 3 AM and restarted at 4 AM.
  A customer message is triggered at 4 AM, which resets the seed list timer.
  The seed list is sent at 4 AM and again at 10 AM (6 hours after restart).

Subject lines for seed list emails

The Subject line for an email sent to the seed list has the following format:

• Seed List - {$original subject line} : ( {$seed list name}, {$customer email address} )
• BCC - {$original subject line} : ( {$customer email} )

For example, if the Subject line is "Best scooters in town", the customer email address is 'firstname.lastname@company.com' and the seed list is 'Default Seed List', the subject line has the following format:

• Seed List - Best scooters in town: (Default Seed List, firstname.lastname@company.com)
• BCC - Best scooters in town: (firstname.lastname@company.com)
