Ability to send emails immediately when someone submits a form

Its important when someone is signing up for anything or submitting any kind of form that they receive the email response either within the form OR from the associated campaign IMMEDIATELY.

People will lose attention and focus if their email is received even a couple of minutes later.

As you say we have just seconds to capture their attention so if the email takes too long then we lose them.

Even when we manually send an email to someone we are on the phone it takes forever for the email to go and often its after 5 or 10 minutes or even longer before they get it.  I cant have my sales team hanging out of the phone waiting for that long to make sure first time emails dont go to junk mail.

Please, make emails immediate like other systems.
