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 manually upload your initial contact list as a CSV, then work with your developers to set up automatic suppression via API.
For detailed instructions and information, please see the documentation here.
