The Sparkpost integration allows you to easily import your Sparkpost lists into NeverBounce, validate your list and send the validation results back to Sparkpost.

Getting Started

To get started with this integration, login to your NeverBounce dashboard and select “Import from Sparkpost” from the “Add List” dropdown. This will open a dialog and attempt to connect to your Sparkpost account. If you haven’t connected your account yet, a dialog box will open requesting the Sparkpost API Key.

Please follow the instructions mentioned in the link to create application-specific API key. While creating the key, please make sure you allow the key to read/write your recipients list. This can be done by clicking on the checkbox next to “Recipient Lists: Read/Write” permission.

After saving your Sparkpost credentials, NeverBounce will connect to your Sparkpost account. After a few seconds you should see your Sparkpost lists. Select one and click ‘Import’ to begin importing your list. Once imported, the list can be analyzed and validated just like an uploaded list.

Sending the results to Sparkpost

Once you’ve completed validation, sending the results back to Sparkpost is as easy as pressing ‘Export to Sparkpost. Clicking on ‘Export to Sparkpost’ will start the export process and the button will change to ‘Exported’.

Once the export is completed, we will create a new list containing valid emails from your list. This list would be created by the name “(original list name)-valids”.


My import has been processing for a while, how long does it take? Why isn’t there a progress bar?

Importing can take several minutes for a few thousand contacts and upwards of an hour for larger numbers of contacts. Unfortunately, we are unable to provide a progress indicator as we are unable to retrieve the total number of contacts in a list until importing is completed.

How can I export my catchalls to Sparkpost?

Once the export is complete, click on ‘Exported’ button, which will open a dialog box. You can click on ‘Export Catchall’ button to export your catchalls to Sparkpost. This will create a new list with name as “(original list name)-catchalls”.

How can I export my invalids, unknowns and disposables to Sparkpost?

Currently we do not allow exporting invalids, unknowns and disposables to Sparkpost. However, you can download them via our dashboard and manually import them in your Sparkpost account.
