What if my integration isn't offered?

If you don't see an integration for your email service provider listed in Integrations > Available Integrations, there are a few options for how to have your collected contacts automatically sent to you:

  • Integrate with Generic Webhooks
  • Integrate with Zapier (and set up an integration between Zapier and your current ESP)
  • Manually download the contacts and upload them into your ESP (Note: This option isn't recommended, as you will see the best results if you email the contacts in real-time.)

Suppress contacts

To prevent collecting contacts you already have, you will need to setup automatic suppression via API or manually suppress them by uploading a CSV file.

Suppression via API

You can set up daily suppression via our API. Find more information on that here.

Manual suppression

Suppression lists loaded as a CSV file are converted into encoded MD5s for security reasons. We do not use, share, or resell this data for any purpose other than to prevent users from collecting and paying for contacts they already have.

To upload a Suppression List, click on Suppression Lists in the left-hand navigation.

Here are the file requirements for upload:

  • Your file should only contain ONE column, labeled “email”.
  • You’ll also need to save it as an Excel .CSV file.
  • Maximum file size is 100MB. If your file is larger than this, split it up into several smaller files.

Once the file has uploaded, you will see a green box in the top-right corner that says your file has been uploaded and is in the queue to be processed. Once that’s complete, you’ll see the stored file listed under the corresponding date:

Make sure the Unique Records number matches the number of records in your ESP.

After you upload the initial file, you will need to continue uploading a CSV file to suppress contacts. How often you need to upload a CSV suppression list (ex. daily, weekly, bi-weekly, monthly) will depend on how many contacts you collect in your ESP.
