Generate a Random signature

You can configure Crossware to apply one of several signature blocks at random. Each outgoing email will receive a randomly selected signature. This is useful when you want variety or when you want to test different signature versions.

When the rule runs:

• Crossware stamps an email header called X-CWRandom with a random number.

• The value in this header determines which signature block is applied. For example, if the value is 1, the system applies sub-signature 1. If the value is 2, it applies sub-signature 2, and so on.

Configure random signatures

Create your signature blocks

1. In the Crossware Portal, create all the Signature Blocks you want to rotate between.

2. Give each Signature Blocks a unique identifier such as RAND-1, RAND-2, RAND-3 etc.

RAND-Generate: always returns false, but stamps following field onto the message header X-CWRandom with a random number
RAND-1 : subsignature which is triggered on a X-CWRandom=1
RAND-1 : subsignature which is triggered on a X-CWRandom=2

Add the random number generation code

RAND-Generate

Code:

Random rnd = new Random();
int iRand = rnd.Next(1, 3);
List < string > lRandom = new List < string > ();
lRandom.Add(iRand.ToString());
pEmailHeaders.Add("X-CWRandom", lRandom);
return false;

int iRand = rnd.Next(1, 3); returns a random number between 1 and 2.
Please update this line "int iRand = rnd.Next(1, 3);" for the number of sub signatures eg if there were 6 the line should be, int iRand = rnd.Next(1, 7);

RAND-1

Code:

if (pEmailHeaders.ContainsKey("X-CWRandom"))
{
List < string > sRand=pEmailHeaders["X-CWRandom"];
int iRand = int.Parse(sRand[0]);
if (iRand == 1) return true;
}
return false;

RAND-2

Code:

if (pEmailHeaders.ContainsKey("X-CWRandom"))
{
List < string > sRand=pEmailHeaders["X-CWRandom"];
int iRand = int.Parse(sRand[0]);
if (iRand == 2) return true;
}
return false;
