[Plugin: Contact Form 7] form submissions suddenly being pushes to gmail spam

Hi,

Recently we’ve noticed that all of our contact form 7 submissions are being pushed to Gmail’s spam folder since around July 20th 2016. We haven’t changed anything since we launched the site a year ago and the submissions are coming through on the Contact Form DB plugin.

Is this an issue with gmail?

The only thing I can think of are the additional headers, which are standard “Reply-to” and “bcc:” headers.

The from field is a no-reply address with the site’s domain.

We’re running the latest version of WordPress and CF7.

Thanks!
