Security & Reliability
The Unisender integration utilizes a robust API interface to facilitate seamless email marketing automation, allowing you to manage contacts and handle subscriptions effortlessly. With secure OAuth authentication, only authorized workflows can access your Unisender data. Relevance AI manages API operations (like subscribing and unsubscribing contacts) in the background, ensuring you don’t have to worry about errors, formatting, or limits.
Built-in validation and type conversion guarantee that your workflows run smoothly, even when data formats vary. This integration streamlines your email marketing efforts, automating contact management and enhancing your overall marketing strategy.
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 Unisender + Relevance AI integration without writing code:
- Start with a clean contact list: Ensure clear naming conventions and consistent data formats for emails and phone numbers.
- Use templates: Relevance AI provides pre-built workflows for subscribing, unsubscribing, or updating contacts—perfect for quick implementation.
- Connect carefully: Make sure to approve the correct Unisender account and lists during the setup process.
- Test before scaling: Execute automations on a small set of test contacts first to avoid widespread issues.
- Watch for rate limits: Implement request throttling and batch updates to prevent hitting API limits.
