Using mail_form gem and Sendgrid - having an issue

Kyle Williamson asked in Rails

I'm trying to test sending an email from the page, but I'm not receiving any emails in my inbox. While in the rails console, it looks like the email is sent correctly. I'm just not getting it. I believe I have all the necessary code. I'm following this tutorial as I'm working on my personal web portfolio and I'm making a contact form that will email me directly from the page. Here's the link to the tutorial just in case it's needed: https://www.youtube.com/watch?v=QIoORYeBdhs

I will post my code here as well. I'll try to get the necessary files in.

new.html.erb:

<h1 class="page_title">Say hello!</h1>

  <div class="skinny_wrapper wrapper_padding">
    <%= form_for @contact do |f| %>
      <%= f.label :name %><br>
      <%= f.text_field :name, required: true %>

      <br>

      <%= f.label :email %><br>
      <%= f.text_field :email, required: true %>

      <br>

      <%= f.label :message %><br>
      <%= f.text_area :message, as: :text %>

      <div class="hidden">
        <%= f.label :nicname %><br>
        <%= f.text_field :nickname, hint: 'Leave this field blank' %>
      </div>

      <%= f.submit 'Send Message', class: "button" %>

    <% end %>
  </div>

Contacts controller:

class ContactsController < ApplicationController
  def new
    @contact = Contact.new
  end

  def create
    @contact = Contact.new{params[:contact]}
    @contact.request = request
    if @contact.deliver
      flash.now[:error] = nil
    else
      flash.now[:error] = 'Cannot send message.'
      render :new
    end
  end
end

Contact Model (not generated)

class Contact < MailForm::Base
  attribute :name,      :validate => true
  attribute :email,     :validate => /\A([\w\.%\+\-]+)@([\w\-]+\.)+([\w]{2,})\z/i
  attribute :file,      :attachment => true

  attribute :message
  attribute :nickname,  :captcha  => true

  def headers
    {
      :subject => "Contact Form",
      :to => "[email protected]",
      :from => %("#{name}" <#{email}>)
    }
  end
end 

And just in case, the production.rb file:

Rails.application.configure do
  # Settings specified here will take precedence over those in config/application.rb.

  # Code is not reloaded between requests.
  config.cache_classes = true

  # Eager load code on boot. This eager loads most of Rails and

  # config.action_mailer.raise_delivery_errors = false

  # Enable locale fallbacks for I18n (makes lookups for any locale fall back to
  # the I18n.default_locale when a translation cannot be found).
  config.i18n.fallbacks = true

  # Send deprecation notices to registered listeners.
  config.active_support.deprecation = :notify

  # Use default logging formatter so that PID and timestamp are not suppressed.
  config.log_formatter = ::Logger::Formatter.new

  # Use a different logger for distributed setups.
  # require 'syslog/logger'
  # config.logger = ActiveSupport::TaggedLogging.new(Syslog::Logger.new 'app-name')

  if ENV["RAILS_LOG_TO_STDOUT"].present?
    logger           = ActiveSupport::Logger.new(STDOUT)
    logger.formatter = config.log_formatter
    config.logger    = ActiveSupport::TaggedLogging.new(logger)
  end

  # Do not dump schema after migrations.
  config.active_record.dump_schema_after_migration = false

  config.action_mailer.default_url_options =  { host: 'http://portfolio-kw.herokuapp.com/' }
  config.action_mailer.delivery_method = :smtp
