# Email Delivery Issues - Troubleshooting Guide
## You or your team members are not receiving emails from ACA Landscape (@acalandscape.com), including estimates, invoices, or other important communications.
#### Why This Happens
Modern email systems use aggressive spam filtering to protect users from unwanted emails. Unfortunately, legitimate business emails can sometimes get caught in these filters. Common causes include:
1. **Email Security Gateways** are blocking or quarantining messages from unrecognized senders
2. **Spam filters** are incorrectly categorizing our emails as junk/spam
3. **Domain reputation systems** that haven't yet recognized @acalandscape.com as a trusted sender
4. **Strict email authentication policies** (SPF, DKIM, DMARC) at the recipient's organization
#### Immediate Solutions to Try
**1. Check Spam/Junk Folders**
First, please check your spam, junk, or quarantine folders for emails from @acalandscape.com. If found there, mark them as "Not Spam" or "Safe Sender."
**2. Add to Safe Senders List**
Add our email addresses or the entire domain **@acalandscape.com** to your safe senders or contacts list:
1. **Outlook**: Right-click on an email from us → "Add to Safe Senders"
2. **Gmail**: Add our email addresses to your contacts
3. **Other providers**: Look for "Safe Sender," "Approved Sender," or "Whitelist" options
**3. Contact Your IT Department**
**This is the most effective solution for organizations.** Please forward this information to your IT department or email administrator and ask them to:
1. **Whitelist the domain @acalandscape.com** in your organization's email security platform (e.g., Proofpoint, Mimecast, Microsoft Defender, Barracuda).
2. **Check the email quarantine** for held messages from our domain
3. **Add an allow rule** for emails coming from:
4. Domain: @acalandscape.com
1. Sometimes adding a wildcard email address is helpful: \*@acalandscape.com
1. IP addresses: \[Our IT team can provide these if needed\]
2. **Review email logs** to determine if our messages are being blocked and why
#### **Information for IT Administrators**
To ensure reliable email delivery from ACA Landscape, please:
1. Add @acalandscape.com to your Email Security Gateway's approved sender list
2. Ensure SPF, DKIM, and DMARC checks are not overly restrictive
3. Check if our domain is incorrectly listed in any threat intelligence feeds
4. Review and release any quarantined messages from our domain
#### **Still Having Issues?**
If you continue to experience problems receiving our emails after trying these solutions:
1. Provide us with an alternate email address where we can send communications
2. Let us know what email system or provider you use
3. Ask your IT team if they can provide any bounce-back messages or logs showing why our emails are being blocked
#### **Contact Us**
If you need any additional information to help resolve this issue, please don't hesitate to reach out to our team. We're happy to work with your IT department directly to ensure smooth communication.
*Note: This is a common issue affecting many businesses today due to increasingly strict email security measures. We appreciate your patience as we work together to ensure you receive all important communications from ACA Landscape.*
