Client: Look, I got this email via my contact form on a website.
They sent me a spammy message where the sender says he analyzed their website and could improve ther SEO and traffic.
Me: Oh, this is a spam message, I will try to enhance security in forms to avoid such messages.
Client: I dont care, spam or not. I dont care about that message. Why does somebody analyze my website? And why my SEO and traffic is not improved? I want my website to be found on Google as they are suggesting!
Me: Your website is among the best Google results in your market, and your traffic is huge by the way. You can see this in monthly reports we send you.
Client: I don't need your excuses, fix it.
So I enhanced form security and they stopped receiving those spams. After a month without any spams:
Client: Thank you, it seems my SEO is OK again.
