We use Delivra to handle email marketing and as a part of our inbound marketing efforts for a client. We utilize a sub-account that is part of the client's parent account. It is primarily used by our earned media team. It is comparable to other email marketing/marketing automation platforms, but allows for BCC'ing an internal email address on ALL emails sent from the account. This feature is different from a single compliance copy, and means that if you are sending 1000 personalized emails you can receive all 1000 BCC'd internally. This can be very useful for record keeping.
