Use this Ruby gem to avoid emailing your users from non-production environments.
# Gemfile
gem "recipient_interceptor"
# config/environments/staging.rb
Mail.register_interceptor(
RecipientInterceptor.new("[email protected]")
)
# config/environments/production.rb
My::Application.configure do
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
address: ENV.fetch("SMTP_ADDRESS"), # example: "smtp.sendgrid.net"
authentication: :plain,
domain: ENV.fetch("SMTP_DOMAIN"), # example: "heroku.com"
enable_starttls_auto: true,
password: ENV.fetch("SMTP_PASSWORD"),
port: "587",
user_name: ENV.fetch("SMTP_USERNAME")
}
end
Email will be intercepted and delivered to the provided address with
headers X-Intercepted-To
, X-Intercepted-Cc
, and X-Intercepted-Bcc
added.
Deliver intercepted email to multiple email addresses:
Mail.register_interceptor(
RecipientInterceptor.new(["[email protected]", "[email protected]"])
)
Use a comma-delimited string:
Mail.register_interceptor(
RecipientInterceptor.new("[email protected],[email protected]")
)
Use an environment variable:
# heroku config:set EMAIL_RECIPIENTS="[email protected],[email protected]" --app staging
Mail.register_interceptor(
RecipientInterceptor.new(ENV["EMAIL_RECIPIENTS"])
)
Prefix the subject line with static text:
Mail.register_interceptor(
RecipientInterceptor.new(
ENV["EMAIL_RECIPIENTS"],
subject_prefix: "[staging]",
),
)
Prefix the subject line with contents from the original message:
Mail.register_interceptor(
RecipientInterceptor.new(
ENV["EMAIL_RECIPIENTS"],
subject_prefix: proc { |msg| "[staging] [#{(msg.to + msg.cc + msg.bcc).sort.join(",")}]" }
),
)
The object passed to the proc is an instance of
Mail::Message
.
