This Account Went From 12 to 91
Many brands think email deliverability is random.
They assume inbox placement depends on luck, algorithms, or the platform they use.
It doesn’t.
In reality, email deliverability is usually the result of habits, list quality, sending behavior, engagement signals, and lifecycle strategy.
One account I worked on had dropped to a score of 12.
That is the kind of level where revenue starts slowing down, campaigns underperform, and brands begin blaming subject lines, creative, or Klaviyo itself.
After a focused recovery process, the score improved to 91.
No hacks.
No platform switch.
No aggressive discounting.
Just proper email marketing fundamentals.
Why Email Deliverability Drops
A low deliverability score rarely happens overnight.
It is usually caused by months of small mistakes stacking up.
Common reasons include:
- Sending too often to disengaged subscribers
- Poor segmentation
- Old or unhealthy profiles staying on the list
- High unsubscribe rates
- Low open and click engagement
- Spam complaints
- Weak flow structure
- Irrelevant campaigns sent to everyone
Most brands only notice the issue once sales begin slipping.
By then, sender reputation has already been damaged.
What Changed to Improve the Score From 12 to 91
1. Better Segmentation = Better Audience Quality
Instead of sending broadly, campaigns were focused on engaged audiences.
That means prioritizing people who had recently opened, clicked, browsed, or purchased.
This improves positive engagement signals and reduces negative reactions.
Key takeaway: Sending to fewer but better contacts often outperforms sending to everyone.
2. Smarter Sending Frequency = Less Fatigue
Too many brands over-send.
When subscribers feel overwhelmed, they stop opening, start ignoring emails, or unsubscribe.
We adjusted send frequency and focused on timing.
This reduced fatigue and helped restore engagement.
Key takeaway: More emails do not always mean more revenue.
3. Cleanup of Unhealthy Profiles = Healthier List
Inactive, bounced, or low-quality profiles can hurt performance.
We carefully reviewed list quality and cleaned unhealthy segments.
That creates a stronger foundation for future sends.
Key takeaway: List size means nothing if quality is poor.
4. Reduced Negative Engagement Signals = Better Reputation
Mailbox providers watch behavior signals such as:
- Deletes without opens
- Ignored campaigns
- Unsubscribes
- Spam complaints
Reducing these signals helped rebuild sender trust.
Key takeaway: Reputation is built through subscriber behavior.
5. Better Flow Structure = Stronger Lifecycle Revenue
Instead of relying only on campaigns, flows were improved to support healthier engagement:
- Welcome Series
- Browse Abandonment
- Abandoned Cart
- Post-Purchase
- Replenishment
- Winback
Flows often generate revenue more efficiently because they are behavior-based and relevant.
Key takeaway: Smart flows reduce pressure on campaigns.
6. Patience and Consistency = Long-Term Recovery
Deliverability does not recover overnight.
It takes consistent sending habits, strong segmentation, and disciplined decision-making.
Many brands panic too early.
Recovery rewards patience.
What Did NOT Fix the Problem
These common reactions usually make things worse:
- Sending bigger discounts every weekend
- Blasting the full list more often
- Switching platforms too quickly
- Constant strategy changes
- Ignoring engagement metrics
Deliverability is operational, not magical.
Signs Your Brand May Have a Deliverability Problem
Watch for these warning signs:
- Open rates declining steadily
- Click rates falling
- Rising unsubscribes
- Lower campaign revenue despite same traffic
- Spam complaints increasing
- Flows outperforming campaigns by a large margin
If this is happening, it may not be your offer.
It may be inbox placement.
Final Thought
This account went from 12 to 91 because deliverability was treated as a business priority.
Not an afterthought.
Email deliverability is not luck.
It is the result of:
- Healthy data
- Smart segmentation
- Controlled frequency
- Relevant automation
- Consistent habits
Most brands wait until revenue drops.
The smarter move is fixing the problem before that happens.
