Tips

  • Add a consent checkbox, such as a GDPR Agreement field, and use the feed’s Send only when rule so only people who agree are added.
  • Turn on double opt-in where the service supports it, to keep your list clean.
  • The free plugin also has a simple Mailchimp connection in Settings › Mailchimp. Use the Pro feed when you need groups, several audiences or conditions.
