A WebmasterWorld thread has AdWords advertisers complaining that they received emails from Google pitching the services of an AdWords reseller named Yellowbook.

The email reads:

At first, people were suspicious if Google really sent this email but now everyone seems to be convinced that Google did indeed send out this email.

Why would you be upset. Well, these emails may be going to your clients! Google may send your client an email telling them to stop using your services and consider using Yellowbook.

One AdWords professional said:

I have never seen Google recommend other companies in the past, at least via emails. I have seen rumors of Google stealing AdWords clients and PPC agencies not trusting Google AdWords to not steal from them and even cartoons on the topic.

Yes, Yellowbook is an AdWords partner but how did they convince Google to send this out to some of the advertisers in their network? Was it really from Google? Did it cost Yellowbook anything?

Other AdWords resellers and professionals want answers.
