Is SendGridMessage.OpenTracking.SubstitutionTag Optional?

[kspearrin]

SendGridMessage has an OpenTracking method that requires a enable boolean and substitutionTag string:

public void SetOpenTracking(bool enable, string substitutionTag);

I don't plan to use the substitutionTag. Should I just pass null?

Ex:

sendGridMessage.SetOpenTracking(true, null);

Where will the tracking pixel be placed in this case? At the very bottom of the email?

Hello @kspearrin,

Yes, the substituionTag is optional and we should update this function to reflect that. I'm going to leave this issue open for that purpose.

With regards to the tracking pixel, I'm not sure where it gets placed. I would recommend sending a test email and viewing the source. Alternatively, you can reach out to our support team.

With Best Regards,

Elmer
