Add engage email and domains to your allowlist to maximize delivery and completion

This article walks through how to prevent survey invitations from getting caught by spam or content filters to increase the chance employees see and take the survey.


Assessment Email Delivery

A critical step to ensuring assessment success is making sure that the assessment emails don’t end up in your employees’ spam folders. This can negatively impact your response rates and make you question the validity of the results. 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@emplify.com
  • no-reply@emplify.com
  • noreply@emplify.com
  • *.emplify.com
  • post.spmailtechnolo.com/*

If your email service requires IP-level allowlisting, 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
147.253.223.126 mta-223-126.sparkpostmail.com
