This guide explains what happens when you start using a new email platform and how to transition your sending safely without impacting deliverability.
Why the Platform Introduction Process Matters
When you move to a new email platform, inbox providers don’t automatically trust your sending activity—even if you’ve sent emails before.
You need to:
Rebuild trust with inbox providers
Establish consistent sending patterns
Prove engagement from your audience
This process is essential to maintain strong deliverability from the start.
What is the Platform Introduction Process?
The platform introduction process is the period during which you gradually start sending emails from a new system to establish your reputation.
Even if your domain is not new:
Your sending environment is new
Your sending behavior is being re-evaluated
How It Differs from Warming
Although similar, this process is slightly different from traditional warming:
Warming → Used for new domains or IPs
Platform introduction → Used when switching platforms
Key Steps in the Introduction Process
1. Start with Your Most Engaged Audience
Begin by sending emails to users who:
Recently opened or clicked emails
Are actively interacting with your brand
This helps generate strong positive engagement signals early.
2. Gradually Increase Sending Volume
Avoid sending to your entire list immediately.
Instead:
Start small
Increase volume step by step
Expand to less engaged users over time
This protects your sender reputation during the transition.
3. Maintain a Consistent Sending Schedule
Inbox providers look for predictable behavior.
Best practices:
Send at regular intervals
Avoid sudden spikes or gaps
Stick to a defined cadence

5. Avoid Risky Sending Practices
During this phase, avoid:
Sending to inactive or unverified contacts
Uploading large lists without engagement history
Aggressive sending frequency
These can quickly damage your reputation.
Common Mistakes to Avoid
Sending to your full database immediately
Ignoring engagement signals
Inconsistent sending patterns
Skipping list cleaning before starting
How Long Does It Take?
The platform introduction process typically takes:
2–4 weeks for initial stabilization
Longer for larger or less engaged lists
The timeline depends on:
Your sending volume
Audience engagement
Consistency of your strategy
How It Connects to Your Overall Strategy
The introduction process is just the beginning. Once complete, you should:
Build an engagement-based sending strategy
Continue optimizing segmentation
Monitor performance regularly
