Can't verify DKIM key?

Can't verify DKIM key?

So basically I just wanted to verify the email on my domain so it doesn't showup as spam in other people's inboxes.
So I did what Zoho told me to do, it was to verify a DKIM key. I created the key with the address, added the correct information to the TXT file in my domain's DNS settings, tried to verify it and it keeps saying 'Verification failed'.

I tried it more then once, I reset the DKIM key, and for some reason it just won't verify. Either it's me being impatient or this thing isn't working.
