This feature allows the administrator to perform find and replace on the body of the email and on individual fields within an email. You may for example choose to use an email modifier to remove the text Sent from my iPhone from all messages which are sent by mobile phone users.

Modifiers are grouped under a parent document and can be applied to a Main Signature or to individual sub-signatures.

Order Of Processing


NOTE: Care must be taken when using email modifiers in the order they are processed.

If a signature configuration and sub-signature both contain an email modifier then both email modifiers will be applied. They will be applied in the following order:

  • The other fields from the signature configuration email modifiers will be applied to the email before the signature is appended in the order set in the Order Number field.
  • The body fields will be applied to the email body of the email.
  • The other fields will be applied to the email from the first sub-signature.
  • The Body Field from the first sub-signature will be applied to the body field (including any changes applied from previous signature configurations/ sub-signatures).
  • Apply the email modifiers from any other sub-signatures.
