Google has just released a new service called Postmaster Tools. The idea of this tool is to give you feedback on the reputation of your email domain, helps track who thinks your email is spam, and reports delivery errors. It’s targeted at high volume senders – you have to have 5000 emails sent to Google/Gmail users before it will show you any information. Their blog article describes how to set it up – if anyone has trouble it’s a relatively simple process for us to do it for you, just log a request via the contact page. The average photographer may never see any information in this tool.
Here’s where I start guessing a little… the fact that you have verified your site using this new tool means you care about your website and email delivery, and may send a signal to Google that it’s a high quality, actively maintained site. It may enhance your domain reputation with Google, which could have a very small effect on your SEO. Am I right? I have no idea! But there’s no harm adding it, as it may eventually give you valuable information about your email.
