Have you tested your outbound email with https://mail-tester.com ? I would start there.

However, your TXT record is still not correct. If you have changed it per the other post, then it may take some time to propagate. So in this case, wait at least 4 hours. The SPF record is critical for this.

thanks.
Sorry for late
Just checked in https://www.mail-tester.com/test-0rcbgj7cl

I can not do it that you guide in link, because this not in my email, in receiver: https://knowledgebase.constantcontact.com/articles/KnowledgeBase/6657-get-your-email-into-gmails-primary-tab?lang=en_US
Is related with email an SSL certificate?
Thanks

This seemed like the best article I could find on it: https://knowledgebase.constantcontact.com/articles/KnowledgeBase/6657-get-your-email-into-gmails-primary-tab?lang=en_US

No, this isn’t caused by any setting or server side issue. It’s purely a matter of characterization based on content filters at Google.
