What you’ll need
You don't need to be a developer to set up this integration. Follow this simple guide to get started:
- A Relevance AI account
- A Mailerlite account
- Authorization (you'll connect securely using OAuth—no sensitive info stored manually)
Security & Reliability
The integration enables seamless management of Mailerlite email marketing operations through Relevance AI's platform, utilizing secure OAuth authentication to ensure that only authorized workflows access your Mailerlite data. Relevance AI handles API operations (like creating, updating, and managing subscribers) in the background—so you don’t have to worry about errors, formatting, or limits.
Key benefits include automated subscriber management, group/list operations, and subscriber data synchronization, all while maintaining secure access through OAuth-based authentication.
Built-in validation and type conversion ensure your workflows run smoothly, even when data formats vary. This integration requires an active Mailerlite account, a Relevance AI account, and proper OAuth credentials to function effectively.

To get the most out of the Mailerlite + Relevance AI integration without writing code:
- Start with a clean subscriber list: Ensure that email addresses are valid and that subscriber data is consistent.
- Use templates: Relevance AI provides pre-built workflows for creating, updating, or managing subscribers—perfect for quick setup.
- Connect carefully: Make sure to approve the correct Mailerlite account and OAuth credentials during the integration process.
- Test before scaling: Conduct tests with a small group of subscribers to ensure everything works as expected before applying changes to your entire list.
- Monitor API usage: Be aware of rate limits and use batch operations to manage subscribers efficiently without hitting throttling issues.
