# Common Reasons for Unreceived Email Notifications in Concord
## Sometimes, users may not receive email notifications sent from Concord. This article outlines common causes and provides steps to resolve delivery issues.
### Possible Causes
1. **Email Address Typos**: A missing character or misspelled domain can lead to bounced messages.
2. **Spam or Junk Filters**: Automated emails can get flagged by spam filters or junk folders.
3. **Firewall or Security Settings**: Email server settings, strict corporate firewalls or anti-spam tools can block automated notifications.
4. **Overly Aggressive Email Security Tools**: Tools like Proofpoint, Barracuda, or Mimecast can block certain senders if they aren’t on an approved list.
### Troubleshooting Steps
**1. Verify Recipient's Email Address**
- Confirm that the email address in the “Recipient” field is spelled correctly.
- Ask the recipient to double-check any email forwarding rules on their side.
**2. Check Your Spam/Junk Folder**
- Open your email client and search for emails from [hi@mail.concordnow.com](mailto:hi@mail.concordnow.com) or [hello@mail.concordnow.com](mailto:hello@mail.concordnow.com)
- If you locate the missing emails, mark them as “Not Spam” or add them to your safe sender list.
**3. Add Concord to your Safe Senders list**
Add the following email addresses as Safe Senders (aka Trusted Senders) to your email client:
- [hi@mail.concordnow.com](mailto:hi@mail.concordnow.com)
- [hello@mail.concordnow.com](mailto:hello@mail.concordnow.com)
**4. Whitelist Concord Email Addresses and Sender IP's**
- Ask your IT team to whitelist all emails sent from **@mail.concordnow.com.**
- Provide them with any Concord-specific IP addresses if needed.
**IPs:**
- 50.31.156.96/27 (50.31.156.96 - 127)
- 104.245.209.192/26 (104.245.209.192 - 255)
- 50.31.205.204/30 (50.31.205.204 - 207)
- 50.31.205.0/24 (50.31.205.1 - 255)
**5\. Check Company Firewall and Security Settings**
- If you suspect the company firewall is blocking emails, consult your IT department.
- Request that they allow inbound traffic from Concord’s email-sending domains.
