From Spam Folder to Inbox: An Email Deliverability Recovery Case Study
Email deliverability problems can be one of the most frustrating challenges in email marketing. When emails start going to the spam folder instead of the inbox, open rates drop, conversions decrease, and email marketing performance suffers. In this email deliverability recovery case study, we will walk through a real scenario where email campaigns were going to spam and how the problem was fixed step by step.
This email deliverability recovery case study is designed to help businesses, marketers, and email senders understand how deliverability problems happen and how to fix them. If your emails are landing in spam, this email deliverability recovery case study will show you what to do.
The Problem: Emails Going to Spam
In this email deliverability recovery case study, a small business noticed a sudden drop in open rates. Their open rates dropped from 28% to 6% in just two weeks. After investigating, they discovered that most emails were going to spam instead of the inbox.
Initial Email Performance:
| Metric | Before | After Problem |
| Open Rate | 28% | 6% |
| Click Rate | 4% | 0.8% |
| Inbox Placement | 92% | 35% |
| Spam Placement | 5% | 60% |
| Bounce Rate | 1% | 5% |
These numbers showed a serious deliverability issue, which made this email deliverability recovery case study necessary.
Step 1: Identify the Cause
The first step in this email deliverability recovery case study was identifying the cause of the problem. After checking the system, several issues were found:
- No DMARC record
- Sending volume increased too quickly
- Many inactive subscribers on the list
- Several spam complaints
- No domain warm-up
- Too many promotional words in emails
This email deliverability recovery case study shows that deliverability problems usually have multiple causes, not just one.
Step 2: Pause Email Campaigns
The next step in this email deliverability recovery case study was to stop sending emails for a few days. Continuing to send emails while emails are going to spam can damage sender reputation even more.
Pausing campaigns is an important step in any email deliverability recovery case study because it prevents further damage to your domain reputation.
Step 3: Fix Email Authentication
Authentication is one of the most important parts of deliverability. In this email deliverability recovery case study, the following were set up:
- SPF record
- DKIM record
- DMARC record
After authentication was completed, the domain became more trustworthy. This step in the email deliverability recovery case study helped improve sender reputation.
Step 4: Clean the Email List
The next step in this email deliverability recovery case study was list cleaning. The business removed:
- Inactive subscribers (no opens in 90 days)
- Invalid email addresses
- Hard bounces
- Spam complaint users
After cleaning the list, the email list became smaller but more engaged. This is a key lesson from this email deliverability recovery case study: list quality is more important than list size.
Step 5: Warm Up the Domain Again
Because the domain reputation was damaged, we restarted the warm-up process. In this email deliverability recovery case study, emails were sent slowly and increased gradually.
Warm-Up Schedule Used:
| Day | Emails Sent |
| Day 1–3 | 10 emails |
| Day 4–6 | 20 emails |
| Day 7–10 | 30 emails |
| Day 11–14 | 50 emails |
This warm-up process was a critical step in this email deliverability recovery case study.
Step 6: Change Email Content
Spam filters also analyze email content. In this email deliverability recovery case study, we changed the email content by:
- Removing too many links
- Removing spam trigger words
- Using plain text emails
- Personalizing emails
- Writing shorter emails
Content changes helped improve deliverability in this email deliverability recovery case study.
Step 7: Gradually Resume Campaigns
After authentication, list cleaning, and warm-up, email campaigns were restarted slowly. This step-by-step approach is important in any email deliverability recovery case study.
Results After Recovery
After applying all fixes, the results improved significantly. Here are the final results from this email deliverability recovery case study:
| Metric | Before Recovery | After Recovery |
| Open Rate | 6% | 26% |
| Click Rate | 0.8% | 3.5% |
| Inbox Placement | 35% | 88% |
| Spam Placement | 60% | 8% |
| Bounce Rate | 5% | 1% |
These results show that recovery is possible, and this email deliverability recovery case study proves that deliverability problems can be fixed with the right steps.
