Switching Email Platforms Without Hurting Deliverability

Switching email platforms can temporarily impact your deliverability. This is normal and expected.

Why Deliverability Drops

When you switch platforms:

• Your sender reputation resets

• You may be using a new sending IP

• Email providers no longer recognize your sending behavior

Impact on Your Contacts

You may see:

• Lower open rates

• Emails landing in spam

• Reduced engagement

How to Prevent Issues

1. Clean Your List

Remove:

• Inactive contacts

• Invalid emails

• Spam traps

2. Start with Engaged Contacts

Send to people who already recognize and interact with you.

3. Warm Up Gradually

Increase your sending volume slowly over time.

4. Reintroduce Yourself

Send a simple email like:“You’ll be hearing from me here moving forward.”

5. Monitor Performance

Watch:

• Open rates

• Click rates

• Spam complaints
