Frequently asked questions

Ceven implements a smart queuing system to respect the Reply.io API limits. Since Reply.io enforces strict request per minute caps depending on your plan tier, the agent does not fire requests in a raw burst. Instead, it buffers outgoing calls and spreads them over a window of time. If the agent receives a 429 too many requests response, it automatically triggers an exponential backoff strategy. This means it waits for a short period before retrying, gradually increasing the delay until the request succeeds. This prevents your API key from being temporarily throttled or blocked during large scale contact migrations or campaign audits.
Yes. You can build a workflow where the agent monitors a specific trigger, such as a lead replying with a certain keyword. Once the trigger fires, the agent uses the List Lists and Search Contacts actions to identify the lead and then moves them into a different segment. For example, if a lead says they are interested in a demo, Ceven can pull them out of a cold outreach list and place them into a high priority booking list. This happens in real time, ensuring your sales team is always working on the most current lead status without manual data entry.
Ceven interacts with the underlying data and configuration of your sequences. While the agent does not write the actual email copy in a chat window, it can manage which contacts are assigned to which multi channel sequence. You can create a workflow that assigns a lead to a LinkedIn and email hybrid sequence based on the data found in the lead record. The agent handles the assignment and tracking, while Reply.io manages the actual delivery of the messages across the different channels according to the schedule you set in the platform.
When you use the Delete Campaign action, the removal is permanent within Reply.io. Ceven does not have a recycle bin for these entities. We recommend building a verification step into your workflow where the agent first lists the campaign details and asks for a human sign off before executing the delete command. This is especially important for teams with multiple users managing the same account, as deleting a campaign will stop all active outreach for every lead currently enrolled in that specific sequence immediately.
Ceven can assist by managing the distribution of your outreach. By using the List Email Accounts action, the agent can monitor how many accounts are active and distribute leads across them to avoid hitting provider limits. While Ceven does not manage the technical DNS settings like SPF or DKIM, it can automate the rotation of accounts. If you notice one account has a high bounce rate, you can trigger a workflow to delete that account and provision a new one, keeping your sender reputation healthy across your entire outbound operation.
The search functionality is bound by the Reply.io API pagination. When the agent performs a List Contacts call, it retrieves data in pages. For very large databases with hundreds of thousands of leads, the agent will walk the cursor through each page. This can take a few minutes for the entire list, but for specific searches by email, the response is near instant. We suggest using the Search Contacts by Email action whenever possible rather than listing all contacts and filtering locally to ensure the fastest performance.
If the Search Contacts by Email action returns no results, the agent treats this as a null response. You can configure your workflow to handle this in two ways. Either the agent can trigger a Create Contact action to add the new lead to Reply.io, or it can flag the lead as missing in your CRM. This logic is useful for ensuring that your outreach lists are always in sync with your master lead database without creating duplicate records for the same person.
Yes, the Generate ULID tool is specifically designed for this. Many advanced functions in the Reply.io API require a Universally Unique Lexicographically Sortable Identifier to track tasks and entities. Instead of requiring you to use an external tool to create these strings, the Ceven agent generates them on the fly. When a workflow needs to create a new task or a custom entity, the agent first calls the ULID generator and then passes that unique string into the subsequent API request to ensure the record is created correctly.
