The Bluetooth SIG uses the Marketo platform to communicate with members.  To ensure great email deliverability, please add these IP addresses to your email "Allowlist".

• 199.15.212.0/22
• 192.28.144.0/20
• 192.28.160.0/19
• 185.28.196.0/22
• 130.248.172.0/24
• 130.248.173.0/24
• 103.237.104.0/22
• 94.236.119.0/26

Some anti-spam systems use the email Return-Path field instead of the IP address for allowlisting. In those cases, the best approach is to allowlist ‘*.mktomail.com’, as Marketo uses several mailbox subdomains. If you need any assistance with allowlisting these emails, please send them to your IT department, and they should be able to help you.

This does not impact Working Group reflector emails. If you are still having issues receiving emails, please contact us for further support.
