# Campaign Builder – FAQ

**Q: What if I need to remove a contact from my campaign?**\
If you need to stop mail from going to a specific person, you can upload them to your **Do Not Contact list**. Once a contact is on that list, they will be skipped in all future campaign orders. Learn how to upload to the [Do Not Contact list.](/olc-help-docs/do-not-contact-list-dnc-how-to-upload-and-manage/how-to-upload-a-dnc-file.md)

**Q: Can I mix postcards and letters in one campaign?**\
Yes. You can use any combination of postcards, letters, or other mail pieces in the same campaign. Each one can have its own design and settings.

**Q: How many mail pieces can I add to one campaign?**\
There is no limit. You can add as many mailers and delays as you need to build your full sequence.

**Q: When will I be charged for a campaign order?**\
You will only be charged on the day each mail piece is scheduled to mail. You are not charged for the full campaign upfront.

**Q: Can I edit a campaign after it has been used in an order?**\
Yes, you can edit it. But changes will only apply to future orders that use the campaign. Orders that were already placed will not be affected.

**Q: Will each mailer in the campaign have its own proof?**\
Yes. You will be asked to review and approve the proof for every mailer before you can submit the campaign order.

**Q: Can I reuse the same campaign for multiple orders?**\
Yes. Once your campaign is saved, you can use it again for as many orders as you want.

**Q: What happens if I delete a campaign that has active orders?**\
Deleting a campaign will not cancel any orders that were already placed. Those orders will continue as scheduled. The campaign will just be removed from your campaign list for future use.

**Q: Can I change the delay days later on?**\
Yes. You can go back and change the delay for any part of the campaign at any time before placing a new order.

**Q: Can I pause or cancel a campaign mid-way?**\
You cannot pause a campaign order once it has been submitted. But you can cancel any mail piece as long as it has not entered processing. [Contact Support ](/olc-help-docs/contact-us/how-to-reach-support.md)for further assistance.

**Q: Does the delay count calendar days or business days?**\
The delay uses calendar days. For example, if you set a delay of 7, the next mailer will send 7 days after the one before it, including weekends.
