When sending an email campaign, you have the following options:
An email campaign can be sent multiple times. You can use the same email campaign template and content to send to different groups of candidates or at different times. You can also edit the email campaign before sending it again, if needed.
A test email can be sent. You can send a test email to yourself or to a colleague to preview how the email campaign will look and function. This can help you check the formatting, layout, links, and personalization of the email campaign before sending it to the actual candidates.
