First you need to turn on access for less secure apps https://myaccount.google.com/lesssecureapps
-
Create rails project with rails version > 4
rails _4.2.6_ new sample_email_app -
Add following lines at the end of
config/environment.rbRails.application.configure do config.action_mailer.raise_delivery_errors = true end ActionMailer::Base.smtp_settings = { :address => 'smtp.gmail.com', :domain => 'mail.google.com', :port => 587, :user_name => 'info@example.com', :password => 'password', :authentication => :plain, :enable_starttls_auto => true } ActionMailer::Base.default :content_type => "text/html"

Replace user_name and password with your gmail username and password

Create a mailer file
rails generate mailer UsermailerThis will create a file user_mailer.rb in the app\mailer directory. -
Add following method in user_mailer.rb
def welcome_email(email_address)
mail(to: email_address, subject: 'Test Email')
end- Now we need to create a template file which will be used to email. Create a file welcome_email.html.erb in app/views/user_mailer/ And add the following lines:
<html>
<head>
<meta content = 'text/html; charset = UTF-8' http-equiv = 'Content-Type' />
</head>

Welcome to Test EmailAdd the following lines to routes.rb
root "users#index"
get "users/send_email"- Create a user controller

- Create index.html.erb file in app/views/users/
And add following lines to it:
<p id="notice"><%= notice %></p> <%= form_tag users_send_email_path, method: 'get' do %> <div class="field"> <%= label_tag :email %> <%= text_field_tag :email, nil, style: "width: 100%; max-width: 300px;" %> </div> <div class="actions"> <%= submit_tag "send email" %> </div> <% end %>
