I have a bank of email ready to go, that when I send I tailor the start of to personalise based on a phone call I've just had so I can't use a workflow. I don't want to send the email immediately as sometimes their too long to be written that quickly so it would be great to be able to have the options of delaying the sending of an email for a set number of minutes after pressing send. This was I wouldn't need to task myself to send a follow up email in 15 minutes.
