Everything has been humming along fine. Using SendGrid and your plugin to send automated emails 2x a week showing the latest posts(I do send out any other newsletters). All of a sudden all the post go out using https and not http which is causing the security issue page.I have an SSL for the site but have not set the site to use SSL. I have not made any changes other that creating posts. I did search here and made sure that tracking is off and the default address to the site is http not https. Is there something else I should be looking at.
