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 Thanks Io account
- A Relevance AI account with access to the workspace you'd like to use
- Authorization (you'll connect securely using OAuth—no sensitive info stored manually)
Security & Reliability
The Thanks.io integration platform enables seamless automated direct mail campaigns, allowing you to send postcards, letters, notecards, and gift cards through digital workflows. With features like radius-based targeting and custom handwriting styles, you can effectively reach your audience while managing mailing lists effortlessly.
Utilizing secure OAuth authentication, the integration ensures that only authorized workflows can access your Thanks.io account. The API operations (such as sending mail, managing recipients, and configuring campaigns) are handled in the background, minimizing the risk of errors and ensuring smooth execution.
Built-in validation checks for postal addresses and image URLs guarantee that your campaigns are sent without issues, while the ability to customize messaging and targeting enhances your outreach efforts.
No training on your data
Your data remains private and is never utilized for model training purposes.
Security first
We never store anything we don’t need to. The inputs or outputs of your tools are never stored.

To get the most out of the Thanks.io + Relevance AI integration without writing code:
- Start with a clean mailing list: Ensure recipient data is accurate and formatted correctly to avoid delivery issues.
- Utilize templates: Create reusable postcard and letter templates to streamline your campaigns and maintain brand consistency.
- Connect carefully: Verify that you have the correct OAuth credentials and API access during setup to avoid authentication errors.
- Test before scaling: Send test postcards to a small group to ensure everything looks right before launching larger campaigns.
- Monitor rate limits: Keep track of your API usage and implement exponential backoff to handle rate limiting effectively.
