Rails Action Mailer with Devise - ruby-on-rails

Question

I understand this has been asked before and I've been following Rails ActionMailer Guides as well as looking through a few related questions on stackoverflow. I'm running a localhost and trying to send emails from there. From the rails guides, I followed every step and double checked everything is written as in the guides. I've also read a few questions found here, but still my emails aren't sending from localhost. Also, I'm not getting any errors within my server.

def welcome_email(admin)
#admin = admin
#login_url = "localhost:3000/admins/sign_in"
mail(to: #admin.email, subject: "Welcome to Dog Seeker!")
end
app/admin/admin_controllers.rb
def create
#admin = Admin.new(params[:admin])
respond_to do |format|
if #admin.save
AdminMailer.welcome_email(#admin).deliver_now
format.html { redirect_to(#admin, notice: 'Admin was successfully created.') }
format.json { render json: #admin, status: :created, location: #admin }
else
format.html { redirect_to new_admin_registration_path }
format.json { render json: #admin.errors, status: :unprocessable_entity }
end
end

Another update
I have another mailer that gets sent when a dog is created and that works fine from localhost and with all the above configurations. My guess is the reason that mailers won't send when an admin account is created is due to the devise registrations controller overriding my controller. In other words, it's not hitting my create action in the admin_controller, but is hitting the registration within devises registration controller.
Please let me know if you need additional information.

Had to follow the guide from Devise Wiki and was able to make it work when admins sign up.
