What bulk email service allows objectionable content?

I have several blogs that publish, what many hosting companies like to call, “objectionable content” and often end up in violation of acceptable use policies. I have been prohibited from doing business with some of the larger hosting companies.

I do not engage in malicious acts. I do not spam or send unsolicited emails. I do not send adult content. I send real email correspondences to people who sign up for updates concerning our advocacy work on public lands and special content only available to our paid subscribers.

I can not find a bulk email service that does not prohibit using their services to send objectionable content or that doesn’t place restrictions on free speech.

Any help would be appreciated.
