Emails not working / delayed

massive delays... up to 5 hours...

i am making some changes and it is very difficult to test when the emails take a long time to arrive..

please shed some more light on the matter

I've tested the feature on my end and I can see emails are sending instantly, upon checking your email history seems like you were testing your emails using the test email button in the email wizards, what I would suggest you is to test your emails using a real submission, if you're using a different email address then using the test email button will not send the emails to the addresses you've set up in your form. 

If you're still experiencing delay, please let us know.
