Once your Blast is created using different Elements, you will need to fill out the Sending Info section for your Blast.

To do this, open Blast Editor and select the Sending Info tab on the right side of your screen.

Subject Line

When you click Sending Info, you will first be prompted to enter a Subject Line for your Blast that all the recipients will see.

You will also have the option to include Personalization Fields (First Name, Full Name, Email Address, Work Location, City, etc) to personalize the Subject Line to your Subscribers. To use a Personalization Field, click on the person icon (located to the right of the Subject Line field) and select an option from the drop-down list.

Sender Profile

Underneath the Subject Line, you will see different fields depending on whether or not your Instance has Sender Proxies toggled ON or OFF inside Blast Controls.

Sender Proxies ON

If your Instance has Sender Proxies toggled ON, you will see the option to select a Sender Profile underneath the Subject Line. To do this, click the Select option drop-down to choose one of your Instance’s Sender Profiles from the list.

Sender Proxies OFF

If your Instance has Sender Proxies toggled OFF, you will see the following fields underneath the Subject Line:

  • Name: This the name your Blast will be sent from.

    • Example: If I enter "Maria Steinberg" in the name portion, everyone who receives the Blast will see “Maria Steinberg” next to the email address the Blast was sent from.

      Please Note: There are no constraints on this field. This means you can make the name “Maria & Robbie” if you want to make the Blast appear as if it’s being sent from multiple people.

  • Send From: All recipients of the Blast will see this email as the address the Blast was sent from.

    • If you would like to avoid having the sender email spammed with out-of-office and other replies, you can turn on a separate Reply To email address.

      Warning: Using this feature may increase the likelihood of your Blast being marked as spam, so make sure to do tests and send samples before using a separate Reply To email address.
