For any recurring campaign, you can quickly and easily change its frequency. 

Starting in the Campaigns menu:

• Click on the campaign you want to modify.
• If the campaign has a status of Running or Scheduled, first click the Pause button to enable changes.

• In the Date & Time module, click on the Select Period dropdown and make your new selection:
  • Daily - Send at the same time every day.
  • Weekly - Send on the same day each week.
  • Fortnightly - Send on the same day each fortnight.
  • Month - Send on the same date each month. *
  • Quarterly - Send on the same date each quarter. *

• If the date and time boxes are now outlined by a red box, this just means it's set in the past. Re-set to the next appropriate date and time in the future.

• Click Save & Activate to restart your campaign.

* If you choose a date that is not valid for every recurrence (e.g: the 31st), your campaign will send on the closest valid day (e.g: February 28th)
