If you’re ready, go ahead and publish your campaign. You can always publish it without sharing it (the only way to find it is to share the URL).
Soft Launch/Private Launch – It’s recommended that you do a ‘soft launch of your campaign. Publish it a week before you send any mass emails or start promoting it on social media and share it exclusively with your guaranteed donors (anybody you’re 100% positive will donate when you ask them to). This way the campaign will already have donations and momentum by the time you start your public promotion.
Also remember, once you publish it, you can always extend or shorten it by changing the end date and time of the campaign.
