Can you please re-read my post? Your answer does not address what I said in my post.
I have uninstalled and removed the plugin, so your answer in 1 does not apply.
My WordPress notifications were working fine with no formatting issues prior to installing the SendGrid plugin and now, after uninstalling and removing it, they have no formatting.
Please respond to my post instead of denying that your plugin changes files, because there is no question that it does.
I would also like to know what files the SendGrid plugin modifies so I can undo any changes the plugin made to my website.
Were you able to find what files the SendGrid plugin modifies? I am also trying to undo any changes the plugin may have made.
