Trying to figure out if my emails are working

I have recently verified the DKIM and SPF on my zoho emails, which is supposed to allow it to work while connected to my phone. However when I send a email from my phone to one of my friends, it does not send and I sent it over 20 minutes ago. I have all correct SMTP & IMAP server codes and ports on my phone as I was instructed by the Zoho support team on how to do that.
