email sent by Amazon SES not accepted by gmail

0

Emails generated by our website are sent to Amazon SES via our hosting provider. Since a few days emails to gmail are not delivered , no problem with all other email. Frequency of sending: a few emails a day with about 40 addresses in BCC. From Amazon SES I only got an email with the message: An error occurred while trying to deliver the mail to the following recipients: (followed by a list of gmail addresses) No further explanation why the mail is not accepted by Google. Our hosting provider checked the DKIM en SPF settings. That's OK. Why is Google not accepting?

If emails sent from Amazon SES are not being accepted by Gmail, there could be several reasons for this issue:

  1. Authentication: Ensure that your Amazon SES configuration includes proper authentication mechanisms like DKIM (DomainKeys Identified Mail) and SPF (Sender Policy Framework) records. These help validate that the email is genuinely coming from your domain.

  2. Content: Review the content of your emails. Gmail has strong spam filters, and certain content (e.g., excessive links, certain keywords, attachments) may trigger spam detection. Make sure your email content is relevant and not overly promotional.

  3. Bounce Handling: Properly handle bounce emails. Continuously remove email addresses that bounce from your mailing list to maintain a good sender reputation.

  4. Feedback Loops: Implement Gmail's Feedback Loop service to receive notifications of user complaints and unsubscribe requests. This helps you manage your email list and avoid sending to recipients who don't want your emails.

  5. Volume and Frequency: Gradually ramp up your email sending volume and frequency. Sending a sudden large volume of emails can trigger spam filters.

  6. Blocked IPS: Check if your IP address or domain is listed on any email Blocked list. Being listed can result in email rejection. Use tools like MXToolbox or Spamhaus to check.

  7. Test Emails: Send test emails to Gmail accounts and examine the headers for any error messages or clues as to why they're not being accepted.

  8. Support: If the issue persists, consider contacting Amazon SES support for assistance. They may be able to provide specific guidance based on your configuration and sending practices.
