E-mails sent with risk alert

Your software
My Mautic version is: v2.15.3
My PHP version is: 7.1.33

Your problem
My problem is: Ive set up a campaign to trigger a series of e-mails automatically. They are being sent but they show up to contacts in their e-mail box with a red safety risk alert as in “You sure this content is safe?”. And the content only appears when you click “it’s safe”. I’d like to know how to solve this problem cause it makes the e-mails go to spam files sometimes, some contacts don’t receive the e-mails and it also hurts our credibility.

Thank you,

Vitória Souza

Hey there

What content are you sending ? Have you authenticated your domain and sender.

This sounds like maybe you are sending lots of spam or are using some malicious content…

Hi,
This is probably due to missing authentication in your emails or you are trying to send with phpmail.
Couple of things you can do:

  1. You should get a third party SMTP.
    This is how it’s set up: https://mautic.com/help/email-transport/
  2. Here is another forum where we are discussing email sending in general:
    What tool to use to send millions of e-mails per month
  3. To authenticate your emails, you need to set up DKIM, SPF and dMARC.

One more thing. If you send an email from yourself to yourself via php, than you’ll probably get the spoofing message. Sender and recipient should be always different.

Good luck!
