Not receiving emails?
When you or your guests stop receiving emails from Tallyfy, several factors could be blocking delivery. This comprehensive Tallyfy troubleshooting guide helps resolve email delivery issues and ensures consistent communication.
- 
Verify email addresses are current and correct. Confirm that emails are being sent to the correct, active email address for you or your guests.
 - 
Review your Tallyfy notification preferences. Navigate to
Settings > My Profile > Email Notificationsto verify which email types you want to receive are enabled. - 
Search spam and junk mail folders thoroughly. Tallyfy emails may be automatically filtered into these folders. Mark any found emails as ‘Not spam/junk’ to improve future delivery.
 - 
Request IT team assistance for domain allowlisting. Ask your IT department to allowlist all emails from the domain
tallyfy.com. This prevents corporate spam filters from blocking Tallyfy communications. - 
Verify quarantine systems aren’t intercepting emails. Ensure your organization’s quarantine or spam detection systems allow emails from
tallyfy.com. Your IT team can configure these systems appropriately. - 
Use reliable email providers instead of disposable addresses. Temporary or disposable email services often block or filter automated emails from platforms like Tallyfy. Choose established email providers for consistent delivery.
 - 
Test email server configuration for blocking issues. Use diagnostic tools like mail-tester.com ↗ to identify potential email server configuration problems that might block Tallyfy emails.
 - 
Share guest task links directly as an alternative. When a task is assigned to a guest, copy their guest link and send it via direct communication channels like chat or text.
 
If your IT team needs specific guidance on allowlisting Tallyfy emails, these official resources provide step-by-step instructions:
- Allowlist in G Suite / Google Workspace ↗
 - Allowlist in Office 365 / Microsoft 365 ↗
 - For other email systems, refer to their specific documentation on adding email addresses or domains to a safe sender list (allowlist).
 
Microsoft email systems (Outlook.com, Hotmail, Office 365, Exchange Online) use sophisticated spam filtering that sometimes blocks legitimate emails. Here’s how to diagnose and resolve these issues.
Microsoft operates two separate email infrastructures - understanding which one applies to your situation is critical:
Consumer services (Outlook.com, Hotmail, Live, MSN):
- Personal email accounts ending in @outlook.com, @hotmail.com, @live.com, @msn.com
 - Sender reputation monitored through SNDS (Smart Network Data Services)
 - Users can mark emails as spam or not spam
 - Governed by Microsoft’s consumer email policies
 
Business services (Office 365, Exchange Online, Microsoft 365):
- Corporate and educational email domains like @yourcompany.com or @university.edu
 - Uses Exchange Online Protection (EOP) spam filtering
 - Managed by organization IT administrators
 - Separate filtering policies and controls
 
The troubleshooting steps differ significantly depending on which system is blocking your emails.
If emails aren’t reaching Outlook.com or Hotmail addresses, check Tallyfy’s sending reputation:
Microsoft SNDS portal:
- Visit SNDS ↗[1]
 - Sign in with a Microsoft Account
 - Request access to Tallyfy’s sending IP addresses
 - Check daily traffic light indicators (green = good, yellow = warning, red = blocked)
 - Monitor spam complaint rates and trap hits
 
What the indicators mean:
- Green status: Good sender reputation, emails should deliver normally
 - Yellow status: Some issues detected, delivery may be degraded
 - Red status: Significant problems, emails likely blocked
 - Trap hits above zero: Emails sent to inactive addresses (list hygiene issue)
 - Complaint rate above 0.1%: Users marking emails as spam
 
Note that SNDS only covers consumer services - it won’t help diagnose Office 365 delivery issues.
Office 365 and Exchange Online filtering happens at the organization level. Your IT administrator has tools to diagnose why Tallyfy emails aren’t arriving:
Message Trace (primary diagnostic tool): Your IT admin can run Message Trace in the Exchange Admin Center to see:
- Whether Tallyfy emails reached Microsoft servers
 - Spam Confidence Level (SCL) scores assigned to emails
 - Specific filtering rules that blocked delivery
 - Whether emails went to inbox, junk folder, or quarantine
 
Typical findings:
- SCL 5-6: Email marked as spam, delivered to Junk folder
 - SCL 7-9: High confidence spam, quarantined or rejected
 - Authentication failures: SPF, DKIM, or DMARC checks failed
 - Policy blocks: Organization rules preventing delivery
 
What IT can do to allow Tallyfy emails:
- Add tallyfy.com to the Tenant Allow/Block List
 - Create Mail Flow Rule to bypass spam filtering for Tallyfy
 - Add to organization-wide Safe Senders list
 - Adjust anti-spam policy thresholds
 - Release emails from quarantine and mark as not spam
 
Microsoft requires proper email authentication (especially after May 2025 for bulk senders). Here’s how to verify Tallyfy’s authentication is working:
Using mail-tester.com:
- Visit mail-tester.com ↗[2]
 - Note the test email address provided
 - Send a Tallyfy email to that address (create a test task assigned to yourself)
 - Check your score (should be 10/10)
 - Review any authentication issues flagged
 
What to look for:
- SPF record: Should show “pass” for Tallyfy’s domain
 - DKIM signature: Should be present and valid
 - DMARC policy: Should align with SPF and DKIM
 - Spam score: Should be low (under 3.0)
 
If authentication issues appear, contact Tallyfy support - these are infrastructure-level configurations we manage.
Sometimes Microsoft blocklists sending IP addresses due to spam complaints or suspicious activity. Here’s how to check and resolve:
Check blocklist status:
- Visit Microsoft sender support ↗[3]
 - Enter the sending IP address (Tallyfy support can provide this)
 - Review blocklist status
 - Submit mitigation request if blocked
 
Delist process:
- Provide detailed explanation of issue resolution
 - Wait 24-48 hours for Microsoft review
 - Monitor SNDS for reputation improvement
 - Consider requesting dedicated sending IP from Tallyfy for isolated reputation
 
Note: Delisting only works after addressing the root cause (typically spam complaints or sending to invalid addresses).
If you receive a Tallyfy email in your Junk folder, the email headers contain diagnostic information:
Key headers to review:
X-Forefront-Antispam-Report: Shows SCL score, SPF/DKIM/DMARC resultsAuthentication-Results: Detailed authentication check resultsX-MS-Exchange-Organization-SCL: Spam confidence level (0-9 scale)Received-SPF: SPF check pass/fail status
Your IT administrator can extract and interpret these headers through Message Trace or by viewing the email source.
Beyond reactive troubleshooting, these practices help maintain good email deliverability:
For users:
- Never mark Tallyfy emails as spam - use notification preferences instead
 - Add no-reply@tallyfy.com to your personal Safe Senders list
 - If using Focused Inbox, move Tallyfy to Focused tab
 - Report persistent issues to your IT team promptly
 
For IT administrators:
- Allowlist tallyfy.com domain rather than individual addresses
 - Monitor quarantine for false positives
 - Review spam policies quarterly
 - Document Tallyfy as approved business system
 - Consider tenant-wide Mail Flow Rules for critical workflow systems
 
For Tallyfy administrators in your organization:
- Use reliable, permanent email addresses for members and guests
 - Avoid disposable or temporary email services
 - Maintain clean lists - remove bounced addresses
 - Monitor notification settings to prevent overload
 - Test new processes with small user groups first
 
Reach out to Tallyfy support if you experience:
- Emails blocked despite IT allowlisting Tallyfy domain
 - Consistent authentication failures in mail-tester.com
 - High spam scores (over 5.0) in testing tools
 - Widespread delivery issues across multiple organizations
 - Blocklist issues that persist after delisting
 
We can investigate infrastructure-level issues, coordinate with Mailgun (our email provider), and escalate to Microsoft if needed.
