Hi,
We sent out two emails today to our audience lists and everyone on my team received a notice from Outlook that both emails, 'This sender failed our fraud detection checks and may not be who they appear to be. Learn about spoofing'. We have never received a message like this since we began service with Emma many years ago.

I asked our IT person to look into it and he came back stating that it appears Emma may be blacklisted. One since October 18th. Can you please look into this and let us know the status? Also - are we okay to continue sending emails if this is the status of will most of the emails be blocked from delivery?

Thank you.

Hi Amber,

I'm sorry to see you ran into some issues delivering emails! There are a few things we can do to tackle something like this.

These errors could be domain related so we typically suggest the following:

If you are seeing issues emailing to and from a private domain (i.e.: @atmia.com) it typically can help to whitelist our sending IP addresses. Those are found here:

https://support.e2ma.net/Resource_Center/Account_how-to/how-to-whitelist-emma

Also, updating your SPF record to align with Emma sending can help as well:

https://support.e2ma.net/Resource_Center/Account_how-to/What's_an_SPF_record%3F

Lastly, I found this article that details a bit of these specific issues:

I hope this helps improve sending and please let me know if I can answer any questions!

Thanks,

Zach

Hi,
Thank you for the reply. We already have Emma white listed on our side and have the SPF setup. I also have to assume that others are receiving this notice from the emails. We realistically cannot ask our over 10,000 subscribers to white list Emma and have each comply. How do move forward from here?

Also - please respond on the black list question and screen shot. Were we reading this correctly?

Hi Amber,

Thanks for confirming this. To clarify, I am not suggesting you suggest that on an individual basis, only if you were seeing issues to an internal domain.

I am going to reach out to our delivery team to see if they are able to take a deeper look at the blacklist question you have along with the screenshot attached.

I will follow up with you as soon as I can gain some additional information.

Thanks!

Zach

Hi Amber,

I confirmed with our delivery team that this black list did not affect any emails for this particular mailing. For some more detail on the specific blacklist see the following explanations:

1) No Solicitado is a blacklist that specifically blocks email marketing traffic and does not offer a way to delist IP addresses. We are on that one permanently and, if it is causing issues, it would be for private/corporate domains only. In those cases, it is likely in place because the company has a policy in place restricting email for personal use. There's not much we can do in those cases. 

2) SORBS is an older blacklist that we typically do not address because it affects so little mail ( < 0.1% of all messages sent) and because they often refuse to delist and offer no reason for this action. Since most of the industry has agreed that they are not a reliable source of blacklist data, we don't really worry about them too much. We can be 100% sure that no large ISP or reputable mailbox provider is using this blacklist to block mail. 

I hope this helps shed some light on what you are seeing.

Thanks!

Thank you for the information on the black listing, it helps ease some fears.

Since we have Emma white listed and had our SPF updated, any other suggestions on how not to get this message in the future for our staff? 

I tried clicking on this link but received a webpage saying the account was suspended -

Appreciate your help.

It looks like this page is now redirecting incorrectly, but was simply an article found by searching some of the information your screenshot included.

There isn't anything additional to do for ensuring deliverability from a systems standpoint, we actively manage our sending IP addresses so that is something that is constantly monitored by our delivery team.

We also have put together a general advice resource for deliverability that may be helpful:

Thanks!
