Generally, email invitations sent using SoGoSurvey are delivered almost instantly. However, if you are sending bulk email invitations (more than 1,000 invitations at once), it typically takes between 20 minutes to one hour for all recipients to receive the invitation. This delay is to comply with spam guidelines. We avoid sending too many emails to a particular domain in a given time period.
Sometimes you may run into delivery issues, including email invitations not being delivered or landing in spam. To ensure efficient email delivery within your organization, you may safelist SoGoSurvey. Provide the details listed below to your IT team and they should be able to implement the required changes on your end.
Safelisting helps participants receive invitations. Domain authentication is also strongly recommended to improve sender delivery.
To ensure that emails are delivered to the intended recipients without interruption, please complete the following safelisting settings.
If your firewall blocks access to all traffic except for certain domains, you will need to grant access to our domain as listed below.
Granting access by domain is recommended in preparation for future use of dynamic IP addresses through Akamai CDN.
Certain filters and firewalls may prevent emails from reaching inboxes. This may be the case if you are not receiving SoGoSurvey emails. You (or your IT department) should add our sender domains to your list of allowed emails.
If intended recipients are still unable to receive emails, ask them to add our domains to their email clients, too.
Add your Sender email addresses into the Contact list of the Firewall and/or Web or Mail Client.
If you are using Microsoft Office 365 / Outlook for email delivery, you will need to complete a few extra steps in your Outlook Admin Panel.
- At the top of the screen of the Admin panel, select Settings and then Mail.
- Under Options, select ‘Block or allow’.
- If any of the IP addresses listed below appear on the blocked list, please delete/remove them.
- Add the following domains to the ‘Safe Senders and Recipients’ list:
If you have any additional questions, please contact our team at email@example.com.

Q: Why do safelisting settings change?
A: Our commitment to data security drives these updates. Our recent migration to a Tier-4 data center provides improved security and performance, which means faster speeds for your participants and more power for your analytics.
Q: Why should I safelist an entire domain?
A: To improve delivery quality, we’re shifting from an IP-based model to a domain-based model. This change will allow us greater flexibility in the future to use dynamic IPs and improve your distribution.
Q: Can I just safelist specific IP addresses instead?
A: Safelisting specific IP addresses limits delivery flexibility, but we understand that your team may have security concerns. If you require specific IP addresses, please contact us.
Q: I don’t have time to make any changes now. How long will my “old” safelisting settings last?
A: Our latest migration will be completed by July 17, 2021. We recommend that you update safelisting settings prior to conducting your next project.
Q: Is this the latest version of this reference?
A: Yes, this page always reflects our latest updates.
