It is important to know that every subscriber with Hotmail, Yahoo, or LaPoste has a “report spam” button in their webmail. It then becomes very tempting for some professionals to click on this button, even when they receive a legitimate advertising email, meaning related to their activity and with an unsubscribe link. With one click, their professional address becomes a “private” address, giving them the right to report a perfectly compliant email as spam according to the legislation in force on B To B emailing.

Legislation on emailing to individuals is indeed very different from that applied to professionals. To learn more about the legislation: What are the rules regarding address files?

In conclusion, to avoid abusive spam complaints, we strongly recommend, only in the context of pure B To B prospecting, removing from your opt-out address files all Hotmail, Outlook, Msn, Live, Yahoo, Aol, LaPoste and other free-to-declare generic domains.

By doing so, you eliminate just under 5% of the addresses in your B To B file, and at the same time get rid of over 95% of the problems!

A simple and quick way to implement this recommendation is to add the following domains to your blacklist:

*@aol.com *@hotmail.com *@hotmail.fr *@live.fr *@msn.com *@outlook.com *@outlook.fr *@yahoo.com *@yahoo.fr *@laposte.net *@laposte.net

Of course, depending on the targeted countries, it may be necessary to neutralize other domains: for example *@live.be for Belgium, *@hotmail.co.uk and *@yahoo.co.uk for the United Kingdom, etc…
