Mailkick

Mailkick handles the part of marketing email that is legally load-bearing:
subscriptions and unsubscribes.

What you get

• Subscription lists per user
• unsubscribe_url for your mailer templates
• One-click unsubscribe headers
• Opt-out tracking

Adding it

# Gemfile
gem "mailkick"

Scope

This is not a Mailchimp replacement on its own. Pair it with Action Mailer and a
delivery service and you have covered the newsletter case without exporting your user
list.
