Whitelist Information for SmartSurvey

Note: We do not recommend whitelisting specific servers for allowing emails since their IP addresses could change at short notice and we might add additional servers as the service requires. The correct way is to check SPF/DKIM/DMARC, since the SPF record will always be updated when any details change.

White List our Mail Servers

If you must use whitelisting, and you are experiencing mail deliverability issues, you should send the following list of IP addresses to your IT department to whitelist.

# Hostname IP
1 ms1.ssmx.net 91.146.104.26
2 ms4.ssmx.net 108.61.174.107
3 ms5.ssmx.net 45.76.132.45
4 ms6.ssmx.net 45.77.58.210
5 ms7.ssmx.net 45.76.140.73
6 ms8.ssmx.net 45.77.59.21
7 ms9.ssmx.net 45.77.56.201
8 ms10.ssmx.net 45.76.143.176
9 s1.ssurvey.co.uk 20.90.100.236

 

All of these IP addresses are included in the SPF record: spf.ssmx.net
