Google-forms – How to create a timer in a survey in Google Forms

It's possible but you'll need to do a little scripting

Sending an email after a form submission is such a common task that Google has a complete tutorial to show you how to do it.

Take a look at:

Tutorial: Automating a Help Desk Workflow

Just keep in mind that Google does put limits on the number of emails that can be sent. The limit depends on what type of account you have (ex. Education, Business, etc).

You can check your email use relative to the limit by calling:

MailApp.getRemainingDailyQuota(); 

Google Apps Scripting makes it easy to do complex tasks with some simple scripting. Just keep in mind that there are limits put in place to prevent abuse/spamming.

Google doesn't currently support this feature - there is no way to save a form and have a user return to it later without submitting it.

That does raise an interesting point, though. You can have the user submit the survey and edit their responses later. Instead of forcing the user to page through the rest of the survey to get to the submit button, just add a multiple choice question at the bottom of each survey page (see example below): By using question logic, we can send survey-takers to the "Submit form" page which then gives them an "Edit this form" link that they'll need to save. Of course, when they come back, they will be starting from the beginning of the survey, but their previous answers will remain filled in.

If this all seems complicated (it is), you may want to try one of the paid survey services (I found SurveyMonkey to be a good value for the money, at least a few years ago), which make implementing this much easier (see SurveyMonkey info here).
