Allowing Bonterra Support Emails by IP Address

Updated over a week ago

Sometimes anti-spam systems are stringent and will filter or block messages, even though they contain pertinent information for our users.
​ 
You can help us ensure that this doesn’t happen by working with your IT resources to allow-list our emails and ensure they make it to your inbox. Instructions are below for allow-listing all of our IP Addresses, allow-listing by email return-path, and allow-listing by “from address” – your IT Resources will likely know which option you need, but we can put them in touch with our team if they need additional help.


​Allow-listing IP Addresses

Please ask your IT resource add these IP addresses to your corporate allow-list:

199.15.212.0/24
199.15.213.0/24
199.15.214.0/24
199.15.215.0/24
192.28.144.0/24
192.28.145.0/24
192.28.146.0/24
192.28.147.0/24
94.236.119.0/26
37.188.97.188/32
185.28.196.0/24
103.237.104.0/24
103.237.105.0/24
52.206.211.240


​Allow-listing by Email Return-Path

In the case that your anti-spam system uses the email Return-Path field instead of the IP address for allow-listing, the best approach is to allow-list ‘*.mktomail.com’. This will ensure that all of the mailbox subdomains that are used by our email-sending solution are included.​ ​

Allow-listing by “From Address”

If your anti-spam system allow-lists based on the From address, be sure to include "@socialsolutions.com" and "@bonterratech.com" on your allow-list.
