Each company has unique needs. While many users decide on a plan based on feature requirements, these are the general guidelines we had in mind:
- Free Plan: Designed for companies with basic document notification needs or who want to try OtterDocs before choosing a paid plan.
- Starter Plan: Designed for companies that are starting to level up their document notification capabilities.
- Professional Plan: Designed for companies that have more complex client targeting and segmentation needs.
- Enterprise Plan: Designed for companies with sophisticated document notification needs or companies that would like an annual contract.

Yes, if you are interested in upgrading your plan or would like a custom annual contract with volume-based pricing, contact our Sales team.

If you are on a Starter or Professional Plan, these plans are month-to-month, and you can change your plan or downgrade to free at any time without penalty by speaking with your account rep. If you are on an annual Enterprise Plan, talk to your account rep to make changes. If you downgrade, your account will lose access to the premium features in your current tier.

OtterDocs' secure Document Notification API gateway is an Application Programming Interface that allows document notification messaging functionality to be integrated into business applications or systems. This provides a way to programmatically send and receive notification SMS messages, as well as manage various aspects such as notification templates, message delivery and reporting. By integrating OtterDocs' Document Notification API into your applications or systems, users can receive alerts, notifications, and other messages via SMS — a convenient and cost effective way of communicating important information.

- Increased Reach: SMS messages can be delivered to virtually any mobile phone, regardless of the brand or carrier.
- Increased Engagement: Received messages are more likely to be read than emails and can prompt customers to take immediate action.
- Increased ROI: A cost-effective way to reach customers and drive engagement.

Yes. All document notification requests are processed through our secure API gateway using encrypted connections. We never store sensitive document content — only delivery metadata needed to track and report on message status.

OtterDocs is built for real-time delivery. The majority of SMS notifications are delivered within seconds of being triggered through the API. Delivery times may vary slightly depending on carrier routing, but our platform is optimized for speed and reliability at any volume.
