Tips
- Mailchimp uses OAuth, not API keys. You authorize Rocket through Mailchimp’s login flow. No keys to copy or rotate.
- Free tier includes 500 contacts and 1,000 sends per month. Automation and scheduling are not available on the free plan. Upgrade for larger audiences and features like A/B testing.
- Campaign design happens in Mailchimp. Rocket can trigger sends and manage subscribers, but visual email template editing is best done in Mailchimp’s built-in designer.
- Manage audiences in Mailchimp. You can add subscribers through Rocket, but removing contacts, managing compliance, and editing audience settings must be done in the Mailchimp dashboard.
- One Mailchimp account per project. Each Rocket project connects to one Mailchimp account.
