First in a new series: Who hosts what mail? MBP Spotlight is the brand new series here at Spam Resource where I’ll share ranking data for the top mailbox providers (including B2B!) based on where they fall in the top ten million domains. Some entries might have more info, some entries might have less, depending on what information I know about them and what information I can find online.
To count rankings, I took a snapshot of MX records for the top ten million domains, and then rolled them up based on the domain name hosting mail for each domain. That shows me how many domains have their inbound email hosted by hosted by “*.google.com,” “*.outlook.com,” etc.
What are they? Google is an American multinational corporation and technology company focusing on online advertising, search engine technology, cloud computing, computer software, quantum computing, e-commerce, consumer electronics, and artificial intelligence (AI).
When looking up MX records for Google-hosted domains, here’s what you need to know:
If the domain (not the MX record, but the actual recipient domain) is gmail.com or googlemail.com, it’s a Gmail consumer webmail domain. There’s only two of them – there are no regional variant domains for Gmail. That second domain (googlemail.com) is a lingering byproduct of past trademark conflict issues.
If the domain’s MX record is “smtp.google.com,” then that’s probably a domain owned by Google.
Everything else is going to be the (primarily) B2B “Google Workspace” customers, hosting their custom domain email.
