Frequently asked questions

Ceven manages the entire asynchronous lifecycle of a bulk upload. The agent first uploads your CSV or TXT file using the send file action and then enters a polling loop. It checks the file status at regular intervals to see if the processing is complete. Once ZeroBounce marks the job as finished, the agent automatically downloads the result file and maps the validity status of each email back to your original records in your CRM or database. This removes the need for you to manually log into the ZeroBounce dashboard to download results and reupload them to your marketing tool.
Yes. Ceven uses the ZeroBounce email finder tool to locate professional email addresses. When you provide a person name and a company domain, the agent queries the ZeroBounce database to find the most likely email match. To ensure the highest deliverability, the agent typically follows this discovery with a validation call. This two step process ensures that the found email is not only the correct one for that person but is also currently active and safe to send to, preventing your account from being flagged for bounces.
No. Ceven connects to your existing ZeroBounce account via API. All credit consumption for validations, AI scoring, and email finding is deducted directly from your ZeroBounce credit balance. You can use the get credit balance action within a Ceven workflow to monitor your remaining credits. We recommend setting up an alert workflow that notifies you via Slack or email when your ZeroBounce balance drops below a certain threshold so you can top up your credits and avoid any interruptions in your lead scrubbing automation.
Validation checks the technical existence of an email address, verifying the domain, the MX records, and the mailbox status to see if it will bounce. AI scoring goes a step further by analyzing the quality of the email address based on patterns and historical data to predict the likelihood of engagement. Ceven can use both in a sequence. For example, the agent can first validate an email to ensure it is deliverable and then apply AI scoring to prioritize leads that are more likely to respond, allowing your sales team to focus on high value targets first.
While Ceven can handle massive volumes, you are subject to the API rate limits of your specific ZeroBounce plan. For example, some lower tier plans have stricter limits on how many requests can be made per second for single validations. If a workflow hits a rate limit, Ceven implements an exponential backoff strategy, meaning it will wait and retry the request automatically. For extremely large lists, the agent will always prefer the bulk file upload method over single API calls because it is more efficient and avoids triggering rate limits on your ZeroBounce account.
Activity data provides insights into whether an email address has shown recent engagement, such as opens or clicks. Ceven pulls this data after a successful validation. You can build a workflow that segments your list based on this information. For instance, if an email is valid but shows no activity in the last six months, the agent can move that lead to a re engagement campaign instead of your primary sales sequence. This ensures you are not wasting your sender reputation on dormant accounts that are technically valid but practically dead.
Yes. Ceven can manage your allow list and block list programmatically. If you have specific internal domains that should never be flagged as risky, or competitor domains that you want to block from your marketing funnels, the agent can update these lists in real time. This is useful for companies that frequently change their targeting criteria. You can trigger a workflow to add a new domain to the block list across your entire organization the moment a competitor is identified, ensuring no further credits are spent validating those addresses.
ZeroBounce stores uploaded files for a limited time after processing. To maintain data privacy and hygiene, Ceven includes a cleanup step in its bulk workflows. After the agent has successfully downloaded the results and updated your downstream systems, it calls the delete file action. This ensures that your sensitive lead lists are not sitting on a third party server longer than necessary. You can configure this to happen immediately after the data is synced or on a scheduled basis to keep your ZeroBounce account clean.
