How many times on the date established for email reminders to be sent will those reminders go out.

How many times on the date established for email reminders to be sent will those reminders go out. 

It appears while I'm testing this out I get reminded every 30 mins or an hour. 

Is that how things are set up or can we control that individually?

Thanks

I assume you're referring to the reminder email on Publish tab?

If yes, you have to select either daily, weekly or monthly. If you want to send it to a specific time, there's also an option for that. This will stop automatically if you define an end date. If No end date is set, it will run forever until you delete the reminder.

And here's how to delete a reminder email after it's configured.

However, if you're referring to the Send Emails Later in the autoresponder settings, you can select between the predefined options. It will be sent only once. If you have multiple autoresponders, you will also receive each of them.
