It’s not clear whether you’re after individual emails for each step, or one long summary email, but yes, it’s certainly possible. The steps that you mentioned look like custom methods, so you can add a call to
$evm.execute('send_email',...), as follows:
to = 'email@example.com'
from = 'firstname.lastname@example.org'
subject = 'Infoblox report'
body = 'Got public IP A in Infoblox servername XXX
$evm.execute('send_email', to, from, subject, body)
Hope this helps,
