My site does not load with anything after version 1.6.
I’m unsure why. I walked back all the plugins and the 1.5.13 plugin was the last one that worked. Did you make any major changes in that release that I’m overlooking.
Yes. Added email logging.
If your site is not loading, you should install the Debug plugin and enable WP_DEBUG_LOG to find out why. See Debugging in WordPress.

Also integrated the Postman Gmail Extension plugin into this one. You weren’t using the Gmail API were you?
