Frequently asked questions

Ceven monitors your Tomba credit balance by calling the usage statistics endpoint before initiating large batch processes. If a workflow is designed to enrich a list of five hundred leads but your account only has two hundred credits remaining, the agent will pause the execution and send you a notification. This prevents the workflow from failing silently halfway through a run. You can set up a specific alert in Ceven that triggers when your Tomba credits drop below a certain threshold, allowing you to top up your plan before your sales sequences are interrupted. This ensure that your lead generation pipeline remains fluid and predictable without manual balance checks.
Yes. The agent uses the domain status tool to check if a target email belongs to a disposable provider or a generic webmail service like Gmail or Yahoo. When you build a workflow, you can instruct the agent to only create a lead if the domain status returns as a professional business domain. This means your CRM stays clean and your sender reputation is protected because the agent automatically discards high risk addresses before they ever enter your mailing list. This process happens in real time as the agent iterates through your target list, ensuring only high quality B2B contacts are processed for outreach.
Ceven manages your Tomba connection through secure encrypted tokens. While the agent can list and delete API keys using the available tools, it never exposes the raw secret key in the workflow logs or to the end user. When you connect Tomba, Ceven stores the credential in a secure vault. If you need to rotate your keys for security reasons, you can use the delete API key action within a Ceven workflow or update the connection in your settings. The agent then uses the updated token for all subsequent requests to the Tomba API, ensuring that your data access remains secure and uninterrupted.
Ceven handles bulk imports by iterating through your source data and calling the create lead endpoint for each record. Because Tomba processes leads individually via the API, the agent manages the rate limiting and sequencing to ensure no records are dropped. You can provide a CSV or a Google Sheet, and the agent will map the columns to Tomba lead attributes. If the agent encounters a duplicate or an invalid email format, it logs the error in a summary report and continues with the rest of the list. This allows you to move thousands of prospects into Tomba without manual entry.
When the Tomba finder returns no results for a specific person or domain, the Ceven agent follows the logic path you define in your workflow. You can set it to skip the lead entirely, flag it for manual review in a Slack channel, or try an alternative search pattern with a different job title. The agent records the unsuccessful attempt in the workflow history so you know which prospects were unreachable. This prevents your sales team from wasting time on dead ends and allows them to focus only on the leads that Tomba successfully verified and delivered.
One important quirk is that Tomba API rate limits are strictly tied to your subscription tier. If you are on a basic plan and trigger a massive bulk enrichment workflow, you may hit a 429 rate limit error. Ceven handles this by implementing an exponential backoff strategy, meaning the agent will wait a few seconds before retrying the request. However, if you consistently hit these limits, the workflow will slow down significantly. We recommend checking your usage statistics through the agent frequently if you are running high volume tasks to determine if a tier upgrade is necessary for your current outbound scale.
Absolutely. The agent can use the list lead lists and update leads list actions to organize your data. For example, you can build a workflow that creates a new list in Tomba for every new marketing campaign you launch. As the agent finds verified emails, it can assign them to the corresponding list based on the lead attributes. This allows you to segment your prospects by industry, region, or company size directly within Tomba. If a campaign ends, you can tell the agent to delete the list or rename it for archiving, keeping your Tomba workspace organized and easy to navigate.
Ceven can be configured to run recurring verification workflows. You can set a schedule where the agent pulls your existing leads from Tomba every thirty days and runs a fresh domain status check. If a domain is suddenly flagged as disposable or if the email no longer validates, the agent can update the lead record or move it to a bounce list. This proactive maintenance prevents your bounce rate from climbing over time. By automating the cleanup process, your sales team always works with a fresh dataset, which improves your overall email deliverability and protects your domain health.
