I've actually notified my paying customer list via direct email about this issue, and then instructed those people affected who have GoDaddy as a host to open up a trouble ticket with GoDaddy directly.

Hopefully they'll eventually realize this is an issue that needs to be resolved.

With the Internet, no email is guaranteed delivery. However, our double opt in servers have higher reputation and will slightly edge out single opt in messages with reaching the inbox.

Rest assured we are working all of our connections at GoDaddy to have this resolved as quickly as we can. There's only so much we can do when they reply with "Please check the settings of your MX records of your DNS registrar" (and that's GoDaddy).

If you wish, please open up a support ticket with GoDaddy and let them know of the issue so there's a ticket on file so they can investigate and elevate this as necessary.

Thanks,
Joe

I hate to be the bearer of bad news but it is not always working with Double Opt In

The double opt in does not guarantee delivery. I personally am double opted in and can not receive emails from infusion always to my personal email which is served by Godaddy.

I am very frustrated with being caught in the middle of an email dispute between Godaddy and Infusion.

We segment our emails that go out into various states/categories; liberating us from a complete and total block. This will work for you. To learn how to properly double-opt-in your contacts, read this article on the Fusebox.

As an alternative, you should be alright sending your users a Double Opt In message, encourage them to confirm their opt-in status and then send them messages. It's a pain, but that should work.

Thanks again for your understanding and patience as we work through this together.
