Email Detected

Email Detected is a simple tool for verifying an email address exists. It's free and quite easy to use 😄 .

Many times as developers we were putting validation statements for checking email addresses format. This gem will complete your existing setups with validator that actually connects with a given mail server and asks if the address in question exists for real.

Installation

Add this line to your application's Gemfile:

gem 'email_detected'

And then execute:

$ bundle

Or install it yourself as:

$ gem install email_detected

Usage

To get info about realness of given email address, email_detected connects with a mail server that email's domain points to and pretends to send an email. Some smtp servers will not allow you to do this if you will not present yourself as a real user.

This only needs to be something the receiving SMTP server. We aren't actually sending any mail.

First thing you need to set up is placing something like this either in initializer or in application.rb file:

EmailDetected.config do |config|
  config.verifier_email = ENV['SENDER_EMAIL_DETECTED']
end

Then, adding your env config with:

SENDER_EMAIL_DETECTED=your-real-email-config

Note: verifier_email must be real.

Then just put this in your model e. g:

validates_exist_email_of :email

Or - if you'd like to use it outside of your models:

EmailDetected.exist?(youremail)

This method will return with status true || false and message look like:

{:status=>true, :message=>"The email address has already been registered."}

{:status=>false, :message=>"The email address invalid."}

or will throw an exception with nicely detailed info about what's wrong.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
