Overview
Treez Loyalty provides built-in tools to communicate with your customers across multiple channels:
Email campaigns and automations
SMS and MMS messaging
Push notifications (if enabled)
To ensure your messages reach customers' inboxes successfully, proper domain setup and a structured sending warmup are required.
How Email Sending Works
Emails sent through Treez Loyalty are delivered using Amazon Simple Email Service (SES).
This means:
Your domain must authorize Treez to send emails on your behalf
Inbox providers (Gmail, Outlook, Yahoo) evaluate your domain reputation
Proper setup directly impacts inbox placement vs spam
Required Domain Setup
To ensure successful delivery, the following DNS records must be configured.
SPF (Sender Policy Framework)
SPF defines which services are allowed to send emails from your domain.
Example:
v=spf1 include:spf.protection.outlook.com include:amazonses.com ~all
Important:
Only one SPF record is allowed per domain
All sending services must be included (Google, Outlook, Treez, etc.)
Missing amazonses.com can cause delivery failures
DKIM (DomainKeys Identified Mail)
DKIM adds a secure signature to your emails.
Confirms the message has not been altered
Builds trust with inbox providers
Improves deliverability
Treez will provide DKIM records during setup if needed.
DMARC (Domain-based Message Authentication)
DMARC tells receiving servers how to handle failed authentication.
Common policies:
p=none → monitor only
p=quarantine → may route to spam
p=reject → may block emails entirely
Recommended approach:
Start with p=none during setup and warmup, then move to stricter policies once performance is stable.
Email Sending Warmup Process
If you are using a new domain or have not sent emails recently, you must gradually increase sending volume.
This helps build domain reputation and prevents emails from being flagged as spam.
Why Warmup Matters
Sending too many emails too quickly can:
Trigger spam filters
Damage your domain reputation
Impact future campaign performance
Recommended Warmup Schedule
Week 1: Send to 5–10% of your audience (Focus on highly engaged users)
Week 2: Increase to 15–25%
Week 3: Increase to 30–50%
Week 4+: Gradually move to full audience sends
Audience Selection (Critical)
Start with:
Recent purchasers
Customers who recently opened or clicked emails
Active loyalty members
Avoid:
Old or inactive contacts
Large unengaged lists
Best Practices During Warmup
Send consistently (avoid large gaps between campaigns)
Use a consistent “From” email address
Gradually increase volume
Monitor engagement metrics
Common Deliverability Issues
If emails are going to spam, review the following:
Multiple SPF records exist (only one allowed)
amazonses.com is missing from SPF
DMARC policy is too strict too early
Sending volume increased too quickly
Audience is unengaged
