Hi @bonnie 

Take a look at this article for context: https://www.technipages.com/gmail-this-message-seems-dangerous

Thank you, @Troy Tessalone!

I appreciate your help finding this article!

While our email body only has 2 links and no images, we do have 4 social media links in our email signatures. I’ll try removing those in hopes it stops these errors.

Thank you,

Bonnie

There are many factors that could contribute to Gmail warning message being shown.

One includes spoofing, where an email appears to come from yourself but is really being sent from another app.

One end user receiving this email may see that warning message, whereas another end user receiving this email may not.

Hey all, I just wanted to follow up to add some more suggestions here! 

There are a number of things you can try to help prevent your emails being seen as potentially dangerous:

• Do not use CSS or HTML to hide content within your messages.
• Don’t embed lots of images. 
• Check for and fix any broken links. And don’t include links that run multiple redirections.
• Avoid adding lots of recipients.
• Keep links in the email body and signature to a minimum.
• Avoid attaching a lot of files. 
• Ensure the email is well written and don’t use too many spam trigger words.
• Avoid having the same email address in the From and To fields.
   

Useful resources:

• Use Postmaster tools to get more information about the emails you’re sending to users.
• Gmail has a guide on how to Prevent mail to Gmail users from being blocked or sent to spam which may be useful. 
• The article Troy linked to here previously also has some good suggestions.
   

Bulk/high volume emails:
If you are sending a high volume of automated transactional emails or newsletters/campaigns, it may be best to switch to a dedicated high-volume email provider like the ones listed here:

• Email Newsletters
• Drip Emails
• Transactional emails
