[](http://travis-ci.org/balexand/email_validator)
## Usage
Add to your Gemfile:
```ruby
gem 'email_validator'
```
Run:
```
bundle install
```
Then add the following to your model:
```ruby
validates :my_email_attribute, :email => true
```
## Strict mode
In order to have stricter validation (according to http://www.remote.org/jochen/mail/info/chars.html) enable strict mode. You can do this globally by adding the following to your Gemfile:
```ruby
gem 'email_validator', :require => 'email_validator/strict'
```
Or you can do this in a specific `validates` call:
```ruby
validates :my_email_attribute, :email => {:strict_mode => true}
```
## Thread safety
This gem is thread safe, with one caveat: `EmailValidator.default_options` must be configured before use in a multi-threaded environment. If you configure `default_options` in a Rails initializer file, then you're good to go since initializers are run before worker threads are spawned.
