I am specifically struggling with Contact Form 7. The Mail From field seems to demand the email address I specified when setting up my GoDaddy WordPress Hosting plan. I wish to instead use an @gmail address. Seems to me, the best solution would be to change the originally specified email address, which is not a working address, to the @gmail address; problem is, I don’t see how to do that. Making the change within WP Settings … General … Email has not corrected Contact Form 7’s desire for the original address.
