Frequently asked questions

Ceven includes a built in queuing system specifically for Reply.io to prevent 429 errors. Reply enforces strict rate limits on their API based on your plan tier, meaning bulk updates to contact lists or large scale blacklist changes can trigger temporary blocks. When the agent detects a rate limit hit, it automatically pauses the workflow and uses an exponential backoff strategy to retry the request. For very large lists, the agent will process the updates in smaller batches over several minutes rather than attempting a single massive call, ensuring your account remains in good standing with the Reply API gateways.
Yes. This is a primary use case for the integration. You can set up a workflow where the agent monitors a source like a Google Sheet or a CRM. When a lead reaches a certain status, the agent uses the Move Contacts to Lists action to shift them into a new Reply segment. This ensures that your outreach is always aligned with the current stage of the buyer journey. The agent handles the lookup of the list ID and the contact ID automatically, so you only need to define the logic for when the move should happen.
No. Ceven only pulls template metadata and IDs when you ask it to list available templates. If a workflow needs to use a template, it tells Reply which template ID to apply to a contact rather than downloading the content and re uploading it. This keeps your intellectual property within the Reply platform and ensures that any global changes you make to a template in the Reply dashboard are reflected instantly in the campaigns the agent is managing, as the agent refers to the template by its unique identifier.
The agent can both read and write to your Reply blacklist. You can create a workflow that scans your incoming emails for specific phrases like unsubscribe or stop. When the agent finds these, it can automatically call the add email to blacklist tool. Similarly, if a domain was accidentally blocked, you can tell the agent to remove that domain from the blacklist. This keeps your sending lists clean without requiring a human to manually enter every single email address into the Reply settings menu every time a lead opts out.
Yes. Using the Mark Contact As Finished action, the agent can instantly halt all outgoing communications for a specific email address or an entire domain. This is critical for preventing awkward situations where a lead has already converted or requested to be removed, but is still active in multiple different campaigns. The agent can trigger this action based on a webhook from your payment processor or a status change in your CRM, ensuring that the lead is silenced across the entire Reply ecosystem immediately.
If a workflow attempts to move a contact to a list ID that no longer exists, the Reply API returns an error. Ceven captures this error and can be configured to alert you via Slack or email. To prevent this, we recommend using the Get All Lists action at the start of complex workflows to verify that the target list still exists and is active. The agent can then dynamically select the correct ID based on the list name, making your workflows more resilient to manual changes made within the Reply dashboard by your team.
Ceven can read your email account configurations to verify that your sending accounts are properly connected and active. While the agent cannot perform the initial OAuth handshake for a new email account due to Reply security requirements, it can monitor for disconnected accounts. If an account goes offline, the agent can notify the account owner to re authenticate. This prevents campaigns from silently failing when a password change or token expiration occurs, ensuring your outbound volume remains consistent and your lead flow is not interrupted by technical glitches.
While the Reply API allows for batch operations, Ceven imposes its own safety limits to avoid triggering spam filters or API blocks. We typically process contact moves in batches of fifty. If you have a list of thousands of contacts to move, the agent will iterate through the list in a loop. This approach is slower than a single bulk upload but significantly safer for your sender reputation and account health. You can monitor the progress of these large moves through the workflow execution logs in the Ceven dashboard.
