Integrate Tidio with HubSpot mailing list (or find alternative to integrate to HubSpot)

We move off our mailing list from Mailchimp to HubSpot. We need someone who has experience in integrating between Tidio/HubSpot, or can recommend an alternative to Tidio so we can send the email entered by the visitor to the mailing list stored in HubSpot. Please describe a similar experience you had in the past. Thank you.
