In short: You are reminded one day before the submission deadline if the Request has not been submitted yet.
How it works
Open the Request via "Fill out request" in the reminder email.
Complete your entries and select "Submit response".
Good to know
Your customer sets the submission deadline. You can see it in the email ("Submission deadline") and on the start page of the Request ("Due on …").
Have you already replied by email? Please still enter your response in Tacto. This is the only way the system can recognize that your response has been received.
