The best way to fix this in my opinion is to host your website with WordPress.com. Ive used many hosts before: Hostinger, Hostgator, Bluehost, InMotion and a few more.
The relief you get after switching over to WordPress.com (Not ww.wp.xz.cn, which is self-hosted). is uncomparable.
The issue you face with the email plugin is automatically taken care of with them because you know, They created WordPress and you host your website with WordPress hosting. Thats the difference. You dont have to worry about nitty gritties of hosting, server things, etc.
Iam taking out a few minutes to write this review, because Ive been in your position in the past where I had to abandon sites because of issues like this and not been able to resolve them correctly.
And my site loads blazing fast on their server, one more added advantage. Even with the most basic plan, the speeds are comparable to Cloud VPS+ level hosting.
Give it a try. Thank me later.
