Frequently asked questions

Ceven uses the bulk import tool to move large groups of users into your lists efficiently. Because Unisender limits each API call to a maximum of 500 contacts, the agent automatically batches your data into smaller chunks. If you try to upload a list of 2000 people, Ceven will execute four separate calls in the background and monitor each one to ensure no records are dropped. You will see a progress bar in the workflow showing how many batches have been processed. This ensures you never hit the per call limit while still moving thousands of leads into your marketing funnel quickly.
Yes. You can use the Create Field action to add new data points to your subscriber profiles. This is useful when you introduce a new product line and need to track interest levels. The agent can create the field in Unisender and then immediately start populating it for specific users based on their activity in other tools. For example, if a user clicks a specific link in your store, Ceven can create a custom field for that product category and mark the user as interested, allowing for much more fine grained segmentation in your future email campaigns.
Unsubscribing is a soft opt out where the contact is marked as unsubscribed but remains in the system. This is critical for legal compliance and ensuring you do not email them again. Excluding a contact is a harder removal that takes them out of the lists entirely. Ceven allows you to choose based on the trigger. If a user clicks an unsubscribe link, the agent uses the unsubscribe tool. If you identify a fake email address or a bot during a cleanup workflow, the agent uses the exclude tool to keep your list hygiene high and your costs low.
The agent uses the Check Email Status tool to query the delivery state of messages sent via the API. It looks for specific status codes that indicate whether the mail was delivered, bounced, or rejected. You can build a workflow that triggers a secondary action if a delivery fails. For instance, if a critical onboarding email bounces, Ceven can automatically create a task in your project management tool for a sales rep to reach out via phone. Note that Unisender only stores these specific delivery statuses for approximately one month.
Absolutely. The agent can create, retrieve, and update templates. This is powerful for businesses with rotating offers. You can set up a workflow that updates the body content of a Unisender template every Monday based on a Google Sheet of weekly deals. The agent pulls the new text, updates the template ID, and ensures the latest version is ready for the campaign. This removes the need to manually log into the Unisender dashboard every week to change a few lines of text or update a promotional image link.
Ceven can create and update notes on any subscriber profile. These notes are tagged as coming from the API so you can distinguish them from manual notes made by your team. This is useful for passing context from a sales call into the marketing tool. When a rep marks a lead as hot in the CRM, Ceven can add a note to that subscriber in Unisender. When your marketing team looks at the subscriber list, they have the full context of the sales interaction without leaving the Unisender environment.
Yes. Unisender imposes rate limits on its API to ensure platform stability. If a workflow attempts to perform too many actions in a short window, such as updating thousands of individual subscribers one by one, Unisender may return a rate limit error. Ceven handles this by implementing an exponential backoff strategy. The agent will pause for a few seconds and then retry the request automatically. To avoid these pauses, we recommend using the bulk import tool for large data moves instead of looping through individual subscribe calls.
Yes. The agent can read all existing tags and apply new ones to subscribers. You can build a workflow that monitors user behavior and applies tags dynamically. For example, if a user visits your pricing page three times in one day, Ceven can add a high intent tag to their Unisender profile. You can then use those tags within Unisender to send a targeted discount code. This allows you to move from generic mass emails to a behavior based strategy where the agent handles the tagging logic in real time.
