Frequently asked questions

Ceven acts as an interface for your Hunter API. Every time the agent performs a domain search, uses the email finder, or verifies an address, it consumes credits from your Hunter account based on your current plan. To prevent unexpected credit exhaustion, you can set up a workflow that calls the account information tool once a day. If your remaining credits fall below a certain threshold, the agent can send you a Slack notification or an email alert. This ensures your automated lead generation does not stop abruptly mid campaign due to a lack of credits.
Yes, Ceven can automate bulk verification. You can provide a list of emails from a CSV or a CRM export, and the agent will iterate through the list using the email verifier tool. Because Hunter has specific rate limits on how many requests can be made per second depending on your API tier, Ceven automatically manages the pacing of these requests. The agent will queue the verifications and only process them at a speed your Hunter plan allows, ensuring that no requests are dropped and your API key remains in good standing.
When the email finder returns no results, the agent can be programmed to follow a fallback logic path. For example, it can trigger a broader domain search to see if any other employees at that company have a similar email pattern. If that also fails, the agent can mark the lead as unreachable in your CRM and move to the next prospect. This prevents your workflow from stalling and ensures you have a clear record of which leads were successfully found and which ones require a manual search effort.
Custom attributes allow you to store data that is not part of the standard Hunter lead profile. Using the custom attribute tools, Ceven can create fields for things like lead source, priority score, or a specific product interest. When the agent upserts a lead, it can populate these custom fields with data pulled from other tools in your stack. This makes your Hunter account a more powerful database for segmentation, allowing you to pull lists based on criteria that you defined specifically for your business needs.
Ceven does not store your lead data permanently. It acts as a secure bridge between Hunter and your destination tool, such as a CRM or an email sequencer. When the agent finds an email, it holds that data in short term memory only long enough to pass it to the next step in your workflow. Once the action is complete, the data is cleared from the active session. Your primary source of truth remains your Hunter account and your chosen CRM, ensuring that you maintain full control over your data privacy.
The domain search tool relies on Hunter's database of public emails. One specific quirk is that for very small or highly private companies, Hunter may return zero results even if the company exists. Additionally, some domains are blacklisted or restricted by Hunter for compliance reasons. If the agent encounters a restricted domain, it will receive a specific error code from the API. Ceven is programmed to recognize these errors and will notify you that the domain is unavailable rather than retrying the request indefinitely.
Absolutely. You can build a workflow where the agent lists all leads within a specific Hunter list and then checks if those leads exist in your CRM. If they are missing, the agent creates a new record. If they already exist, the agent can update the record with the most recent verification status. This keeps your sales team working with a clean list of contacts and ensures that no lead discovered in Hunter is ever lost because someone forgot to manually export a CSV file.
Ceven connects to Hunter using your API key, which is encrypted at rest using industry standard encryption. The agent only uses this key to make authorized requests to the Hunter API endpoints. We do not share this key with any third parties or use it for any purpose other than executing the workflows you have specifically designed. You can rotate your API key in the Hunter dashboard at any time, which will immediately disconnect the agent until you provide the new key in the Ceven integration settings.
