AWS SES Authentication Error Fix -- 2

We are using AWS SES to send transactional emails from a web application.

We are currently facing Gmail delivery issues where emails are being rejected or bouncing. The bounce notifications indicate authentication problems.

Current Setup:

Domain-based sending

DNS hosted on Cloudflare

Email sending via AWS SES (transactional emails from application)

SPF record includes SES and other providers

DKIM CNAME records added in DNS

SES console still shows DKIM as “Not configured”

Gmail headers show:

dkim=none

dmarc=none

DNS propagation appears correct globally.

The Problem:

Gmail rejecting emails

Bounce messages from Amazon SES MAILER-DAEMON

DKIM not verifying in SES

Need to confirm region alignment and identity configuration

Need full authentication alignment

What I Need:

An experienced AWS SES / email deliverability expert to:

Diagnose why DKIM is not verifying

Confirm correct SES region configuration

Validate SPF, DKIM, DMARC setup

Check SPF DNS lookup limits

Verify identity configuration in SES

Ensure Gmail authentication passes

Optimize configuration for stable deliverability

Final Expected Result:

When checking Gmail “Show Original”, authentication should show:

SPF = PASS

DKIM = PASS

DMARC = PASS

No bounce errors. Stable Gmail delivery.
