How do I tie in my rails mailer to Sendgrid using the smtpapi-ruby gem? I've followed their limited documentation, but my emails aren't going through, I've verified that my SendGrid implementation works fine when just sending a plain email, so that's not it. This is what I have:
user_controller.rb
def create
@user = User.new(user_params)
respond_to do |format|
if @user.save
format.html { redirect_to @user, notice: 'User was successfully created.' }
format.json { render :show, status: :created, location: @user }
header = Smtpapi::Header.new
header.add_to(@user.email)
header.add_substitution('user', [@user.name])
header.add_substitution('body', "You've registered! This is from the controller.")
header.add_filter('templates', 'enable', 1)
header.add_filter('templates', 'template_id', 'xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx')
header.to_json
UserNotifier.welcome(header).deliver
else
format.html { render :new }
format.json { render json: @user.errors, status: :unprocessable_entity }
end
end
end
mailers/user_notifier.rb
class UserNotifier < ApplicationMailer
default from: "[email protected]"
def welcome(header)
headers['X-SMTPAPI'] = hdr.to_json
mail(subject: "Welcome to the site!")
end
end
views/user_notifier/welcome.html.erb

I'm not seeing anything come through on the SendGrid activity log, so it's not even getting sent there, at least that's my guess.
What am I doing wrong?
