When it comes to editing your footer external and internal organizations have different options available to them. Internal Communicators have the option to turn off the footer in their Email Blasts because their company owns all the emails they are communicating to. External Communicators don't have the option to turn off their footer because the information is required to be there by law for external accounts sending to email addresses you don't own.

You also have the option to turn on/off the profile image and all social links in your footer. These two options are available for all organizations.

These are default First Names, Full Names, and Email Addresses that are used when a Subscriber does not have valid information to be used in a Personalization Field.

First Name

Last Name

Email Address



EX: I am sending a Blast and using the subject line: "We have some important news for you *|FULLNAME|*." Every subscriber with a first and last name in their account information will have their full name in the subject line of the Blast they receive. But those who do have their full name in their Cerkl account will have a blank space where *|FULLNAME|* would be in their subject line.

It is important to set your fallback personalization fields so you can avoid some of your subscribers receiving emails like this. To learn how to add personalization fields to your Blast check out this article here.

Here you have the ability to set predetermined sender profiles for the Blasts you send out. When sender proxies are turned off any user creating the Blast can edit who the Blast is sent from and what the reply to email is. With sender Proxies turned on Cerkl users can only choose from a set list of sender profiles which are created by those with the Blast Controls permission.
