Mailrail

Mailrail is a provider of email marketing solutions. In practice that means sending campaigns and automated emails to a list and measuring what gets opened.

The natural audience is marketers at companies of every size. They also list Advertising, Email Marketing and Mobile Apps, so expect those to show up in the feature set. As a small product team themselves (11 to 50 people), they tend to serve customers of a similar scale best. You will probably talk to the people who build it, which is great until you need 24/7 support.

Mailrail is based in Milpitas, California. You can read more at mailrail.net.

Things worth asking about: deliverability, list size pricing, and automation depth. Get the renewal terms in writing before the first invoice.
