Thanks for the report, I'll have a look.

I just gave it a shot and did receive the email but it was in my spam folder.
Could you please just double check it is not the case for you too before I investigate further.
Thanks.

Thanks for testing @danhper . There's nothing in my spam folder unfortunately. Did you use a gmail account?

[danhper]

Thanks for checking. No, I used mailgun. I'll try it with Gmail!
