Emails and IP addresses for deliverability
A critical step to ensuring assessment success is making sure that the assessment emails don’t end up in your employees’ spam folders, as this can negatively impact response rates and result validity. For those delivering surveys to corporate email addresses, please consult with your IT team to add the following sending addresses and partner domains to your allowlist:
- surveys@15five.com
- support@15five.com
- *.15five.com
If your email service requires IP-level allow listing, here are the IP Addresses that the invitations will originate from:
| IP | Hostname |
|
192.174.93.53 |
mta-93-53.sparkpostmail.com |
| 192.174.93.52 | mta-93-52.sparkpostmail.com |
| 147.253.223.127 | mta-223-127.sparkpostmail.com |

URLs for survey access
To ensure survey success, it's also vital that employees can access the survey URLs. For those delivering surveys to employees who may be using computers that have internet access blocked, please consult with your IT team to add the following URLs (both http and https) to your allowlist:
- amazontrust.com/*
- fonts.googleapis.com/*
- *.ss2.us/*
