How long after completing online application will the Respondent be contacted?

I completed the online application for divorce on gov.uk and I wondered if anyone has any idea how long it is likely to be until STBXH is first contacted. He is expecting it. He has agreed to confess to adultery after seeking advice. Obviously he will need to sign a confession, but I can't find any information about how long it will take for him to receive the petition, just that I will get email confirmation when it happens.
