Configuring Devise with Sendgrid
Modify the devise configuration file
Locate and edit the config/initializers/devise.rb file
config.mailer_sender = "[email protected]"
I typically use an environment variable for this setting
Modify the Production Configuration
Locate and edit config/environments/production.rb
config.action_mailer.default_url_options = { :host => 'your.websitedomain.com' }
ActionMailer::Base.smtp_settings = {
:user_name => ENV['SENDGRID_USERNAME'],
:password => ENV['SENDGRID_PASSWORD'],
:address => "smtp.sendgrid.net",
:port => 587,
:enable_starttls_auto => true,
:authentication => :plain,
:domain => "yourdomain.com"
}
