No, but...
Once we receive your beamed campaign, a confirmation email is sent back to you with instructions on how to send and a link to edit your campaign. If you don't want to edit your campaign or preview it, you can just reply to the confirmation with the word "Send" above the included line.
Once your response reaches us, we'll go ahead and send the campaign to the entire list!
If you prefer, you can click the link in the confirmation email to edit the campaign (or log in to your account and click edit below the campaign title). You'll be able to change the list you're sending to or send to only a segment, edit your content, preview and send tests, and schedule delivery or send.
