Unable to Deliver Emails to Hotmail, Live, MSN and Outlook?
Outlook.com is putting your legitimate emails into its junk mail folder?
Similarly to AOL, Microsoft domains such as Hotmail, Live, MSN and Outlook also use several criteria to decide whether to deliver an email or block it. If your list contains a certain % of Hotmail/Live/MSN/Outlook email addresses, you’ll want to be aware of some particularities of how Hotmail treats emails. If you’ve already been unsuccessful with delivering an email newsletter to your Hotmail/Live/MSN/Outlook subscribers, you can optimize your email delivery system to meet their requirements and deliver your emails into the Inbox instead of the Junk email folder.

So, here are several interesting facts about Outlook.com that you may want to be aware of before you send your newsletter. As it turns out, with any one of Microsoft’s email addresses – @live.com, @hotmail.com, @outlook.com and others – you’re still really using Outlook.com whether or not you ever visit it on the web:
1. Outlook uses the Sender ID and reverse DNS records to authenticate the sender.
If you don’t have the Sender ID and reverse DNS records properly setup, it doesn’t always mean that your email is deleted or moved to the Junk folder. But it can affect how Hotmail rates your email and how it will treat your subsequent messages. And furthermore, depending on the user’s settings and the reason why the email was not authenticated, the message may be labeled as “unknown sender” in the Inbox that is not good for your brand recognition. Therefore, it’s highly recommended that you setup your Sender ID and reverse DNS records if you don’t have them yet before you send your email newsletter to your Hotmail subscribers. In this article you can read more about the sender authentication and how to get your emails delivered.
2. Outlook is sensitive to the message content.
Avoid spam looking words and phrases in your email and always test your copy before sending it to the whole list. Setup a test email account on Hotmail and send a test email copy to that account. Check whether it arrives into the Inbox or Junk email folder.
3. Outlook limits the quantity of emails you can send at a time.
You can open 500 simultaneous connections to Outlook server or so meaning that you can send 500 emails at the same time.
4. Outlook blocks your messages if you continue sending to bad email addresses.
If an email returns as a hard bounced, you need to delete it from the list immediately. If an email returns as a soft bounced, you can try several attempts to deliver it. If after a few attempts, the email still bounces, remove it from your list too. If you continue sending to non-deliverable email addresses, your activity may be considered as spamming.
5. Outlook provides you with SNDS (Smart Network Data Services).
If you own an IP addresses range, SNDS can give you the information about the traffic originating from those IPs such as a volume of sent emails and complaint rates. The data is collected from the log files of the inbound Hotmail servers and other servers at Hotmail and Microsoft. After you analyze the collected data, you can take measures you see appropriate: increase the host or network security, contact the person or company responsible for the host or act in some other way if you are unsatisfied with the results.

6. Outlook uses old email accounts as Spam Traps.
A spam trap is an email address used to catch spammers because legitimate emails should not be sent at those addresses. If an email is sent to a spam trap address, the owner of the spam trap can complain to your ISP or block your domain or IP.
A Outlook account expires if it is not used during six months. After the six month period an email sent to a dead account bounces with the “550 Requested action not taken: mailbox unavailable” error. After one year of disuse they start using that mailbox as a spam trap. This is another good reason for legitimate marketers to ensure they follow best email marketing practices:
- Send only to recipients who explicitly subscribed to your emails (no purchased, rented or scraped list).
- Send an unsubscribe link, so that the recipient can unsubscribe immediately.
- Use consistent sending IP addresses and domains for your email campaigns.
- Use a consistent From name and From email address to clearly identify your brand.
- Make use of Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) to authenticate your emails.
- Publish reverse DNS with your domain to help identify your IP addresses.
- Track the temporary and permanent SMTP errors from your mail server and act on them accordingly.
- Have a working process of handling bouncing addresses.
- Periodically remove inactive subscribers from your list.
- Don’t reactivate email addresses that are already on your unsubscribe or suppression list.
Firstly, take a closer look at your email collection process. If you are collecting subscribers on your website, you’ll want to use a confirmed subscription process. This is the best way to avoid malicious subscriptions, mistyped email addresses and surely spam trap emails.
Secondly, it’s now more important than ever to deal with your bounces as soon as possible and maintain a clean mailing list. If a message consistently bounces, remove that email address from your list. If you continue emailing to bad addresses, your IP will end by being blacklisted and your emails will not delivered to subscribers. It was just a bad email marketing “etiquette” to send to non-existent emails, but as you see it’s really self-destructive now.
Cleaning a list from bounced emails is a time consuming and tedious work. Better if you could collect bounces and delete them from your contact database at one go. This is exactly what our mailing list management software can do for you. EasyMail7 has a built-in system to automatically process bounced emails: collect bounces from your email account and delete them from your contact groups.
To recap, here is what you should do to deliver your emails to the Inbox:
- validate your email list;
- send to confirmed optin email subscribers;
- periodically suppress inactive or disengaged subscribers from your mailing list;
- remove addresses that bounce consistently;
- honor unsubscribe requests as soon as possible;
- have your domain and IP configured properly in DNS;
- don’t send spammy looking emails.
Following these basic rules is a must for any responsible email marketer.
