A Rails gem for sending emails directly from forms with built-in validations, I18n, attachments, and request information.
MailForm is a Ruby on Rails gem that enables developers to send emails directly from web forms without needing a separate mailer setup. It provides a model-like interface with built-in validations, internationalization, and file attachment support, streamlining the creation of contact forms and similar features. The gem integrates seamlessly with Rails' ActiveModel, making it feel like a natural part of the framework.
Rails developers building contact forms, feedback forms, or any web form that needs to send email notifications directly from user input. It's particularly useful for those who want a quick, convention-over-configuration approach without writing boilerplate code.
Developers choose MailForm because it reduces boilerplate by leveraging Rails' existing ActiveModel features, providing validations, I18n, and a familiar API out of the box. Its simplicity and integration with Rails' ecosystem make it a time-saving alternative to manually configuring mailers and form objects.

Seamlessly inherits validations, I18n, and naming from Rails ActiveModel, allowing form objects to behave like ActiveRecord models, as shown in the example with validates_format_of for email validation.
Defines form attributes with validation rules, file attachments, and captcha spam protection in a simple class, reducing boilerplate for contact forms, as demonstrated in the ContactForm example.
Appends client details like remote IP, user agent, and session to emails by setting the request object, useful for debugging and logging form submissions.
Includes MailForm::Delivery module to send emails on model lifecycle hooks, enabling integration with existing ActiveRecord models without extra code.
Tightly dependent on Rails ActiveModel, making it unsuitable for other Ruby web frameworks or applications not using Rails, which restricts its portability.
Relies solely on a hidden captcha field for spam detection, which is simplistic and may not be effective against sophisticated bots compared to modern solutions like reCAPTCHA.
Supports file attachments but lacks built-in features for file size limits, cloud storage integration, or advanced processing, which could be limiting for media-heavy forms.
