Soft Bounces - 550 5.4.1 - how can I stop this?

DHyett — Tue, 13 Feb 2024 11:51:36 GMT

A portion of all our email campaigns soft bounce with the following error:

Rejected by recipient's email security filter

FILTERED 550 5.4.1 Recipient address rejected: Access denied.

How can I stop this? Is there a setting that is preventing deliverability from our Hubspot end - I am new to Hubspot so not sure if something isn't right on the setup front.

Hi @DHyett,

Have you fully authenticated your sending domain? https://knowledge.hubspot.com/marketing-email/manage-email-authentication-in-hubspot

Best regards

Hi I am experiencing the same issue and have all authentication setup in hubspot. Is there any reason why their email domains are still flagging our sends?
