FAQ - Not Receiving AQai Assessment Invitation Emails?

If participants are not receiving AQai assessment invitation emails, the issue is most often related to email security filtering on the recipient’s side, especially within regulated or enterprise environments such as financial services and government organizations.

This article explains how AQai sends email, what to check, and how recipient IT teams can quickly resolve delivery issues.

How AQai Sends Email

AQai sends assessment invitations from:

• From address: aida@aqai.io

• Sending domain: aqai.io

• Envelope / Return-Path domain: aida.aqai.io

• Email service provider (ESP): Amazon Simple Email Service (SES)

• Region: EU (eu-west-1)

AQai emails are fully authenticated and configured with modern email security standards:

• SPF: Pass

• DKIM: Pass

• DMARC: Pass (policy set to p=REJECT)

This means AQai emails are cryptographically verified and protected against spoofing.

Why Emails May Stop Arriving After Initial Delivery

It is common for the first one or two emails to be delivered successfully, followed by later messages being delayed, quarantined, or silently dropped. This typically occurs due to:

• Adaptive spam or bulk-mail filtering

• Rate limiting or volume heuristics

• URL reputation checks

• Security gateway policy enforcement

In these cases, emails are often accepted by the recipient mail server but intercepted later by a security gateway or firewall.

Sending IP Information (for IT Teams)

AQai uses Amazon SES shared IP infrastructure, which means sending IPs may rotate.

Examples of observed sending IPs include:

• 54.240.7.22

• 54.240.7.35

• 54.240.7.37

Because IPs rotate, whitelisting a single IP address is not sufficient.

Recommended Whitelisting Options

Recipient IT or security teams should implement one or more of the following (listed in order of effectiveness):

1. Allow by Authentication (Preferred)

Permit messages that pass DMARC for the domain:

• aqai.io

This approach is robust and avoids reliance on rotating IP addresses.

2. Allow by Sender Identity

Whitelist:

• From address: aida@aqai.io

• Envelope / Return-Path domain: aida.aqai.io

• Domain: aqai.io

3. Allow by IP (If Required)

If IP-based allowlisting is mandatory, include:

• 54.240.7.22

• 54.240.7.35

• 54.240.7.37

Note: Additional IPs may be used over time due to SES shared infrastructure.

What AQai Can Confirm

If delivery issues occur, AQai can confirm:

• Emails were sent successfully

• No bounces or rejections were received

• SPF, DKIM, and DMARC authentication passed

• Recipient servers accepted the messages

This usually indicates filtering after acceptance within the recipient’s email security environment.

Recommended Troubleshooting Steps

If invitations are missing:

1. Ask your IT team to search email gateway logs (e.g., Proofpoint, Mimecast, Microsoft Defender) for:

   • aqai.io

   • aida@aqai.io

   • Amazon SES sending IPs

2. Check quarantine or held-message folders

3. Apply one of the whitelisting methods above

4. Resend the invitation
