We've been telling you for years that your reputation as a sender is no longer based solely on your IP address, but also on your domain name. This is nothing new.
Well, at the same time, let's face it, this domain name reputation thing is moving slowly. While some players are at the forefront of the field (did I hear "Gmail" in the back of the room?), others are not there yet, others are deliberately playing on balance (in fact they are all playing on balance) or blurring the lines to confuse everyone.
What about phishing?
Unfortunately for you, our friends the spammers (who adapt quickly) went fishing. Trying to pretend to be Paypal in order to extort a few bucks from you, they started to confuse you by using the domain name of the attacked sites, then got thrown out. To get around this, they started using slight variations of the domain name of the attacked sites ... then got thrown out. And so on, it's escalating.
The downside of this is that every time phishers have moved their pawns forward, the filters have reacted accordingly, catching some of the legitimate senders who didn't ask for it in their nets.
Reading content isn't everything. The best way is to talk to us.
For some time now, in order not to get caught in the net of the anti-phishing fight, it is therefore recommended to harmonize the use of your domain names.
Here are the domains that you should try to harmonize in your emails (in order of priority). Good to know, the basic domain is that of your website, it is the center of your identity:
- The sending domain name, i.e. the "From:" field (possibly the "Sender:" field if you use it, but that's for the purists)
- The domain name of your links (including the tracking that your sending platform could generate)
- The domain that signs in your DKIM (I know, it's very technical)
- The domain name of your "Return-Path" (this is the email address to which your bounces are sent) - For purists only
Finally, it is (fortunately) possible to use sub-domains of your main domain (it is even recommended in some situations).
