42. Warming up domeny email

Poziom: Krytyczny | Czas czytania: 10 min

Nowa domena email = zero reputacji = spam folder. Warm-up to proces stopniowego budowania reputacji poprzez kontrolowane zwiększanie volume'u wysyłanych emaili. Skip warm-up = deliverability disaster.

Dlaczego warm-up jest krytyczny?

Nowa domena:

DAY 1: Send 5,000 emails
Result: 
- 40% inbox ❌
- 60% spam folder
- Domain instantly red-flagged by Gmail/Outlook
- Reputation = 0/100

Recovery time: 3-6 months!

Prawidłowy warm-up:

DAY 1-30: Gradual increase 50→2,500/day
Result:
- 95%+ inbox ✅
- Domain reputation = 85/100
- Ready for normal volumes

30-Day Warm-Up Schedule

Conservative approach (recommended):

WEEK 1: Build foundation
Day 1:    50 emails
Day 2:    100 emails  
Day 3:    150 emails
Day 4:    200 emails
Day 5:    250 emails
Day 6:    300 emails
Day 7:    400 emails

WEEK 2: Gradual growth
Day 8:    500 emails
Day 9:    650 emails
Day 10:   800 emails
Day 11:   1,000 emails
Day 12:   1,200 emails
Day 13:   1,500 emails
Day 14:   1,800 emails

WEEK 3: Acceleration
Day 15:   2,200 emails
Day 16:   2,600 emails
Day 17:   3,000 emails
Day 18:   3,500 emails
Day 19:   4,000 emails
Day 20:   4,500 emails
Day 21:   5,000 emails

WEEK 4: Scale up
Day 22:   6,000 emails
Day 23:   7,500 emails
Day 24:   9,000 emails
Day 25:   11,000 emails
Day 26:   13,000 emails
Day 27:   15,000 emails
Day 28+:  Normal volume (monitor!)

Aggressive approach (higher risk):

Week 1:   50 → 500/day
Week 2:   500 → 2,000/day
Week 3:   2,000 → 5,000/day
Week 4:   5,000 → 10,000+/day

Use only if:

• Highly engaged list
• Perfect authentication (SPF+DKIM+DMARC)
• Monitoring 24/7
• Can pause immediately if issues

Warm-Up Rules

Rule #1: Start with engaged contacts

Send to MOST engaged first:

Priority 1: Opened last 10 emails
Priority 2: Opened 7-9/last 10
Priority 3: Opened 5-6/last 10

Skip: Inactive contacts during warm-up!

GHL Smart List:

Filter:
- Email opened in last 30 days
- Clicked link in last 60 days
- NOT bounced
- NOT spam complaint

Sort by: Engagement score (high → low)

Rule #2: Monitor metrics daily

Target metrics during warm-up:

✅ MUST ACHIEVE:
- Delivery rate: >98%
- Open rate: >25%
- Bounce rate: <2%
- Spam complaints: <0.1%

⚠️ WARNING SIGNS:
- Open rate drops below 20%
- Bounce rate >3%
- Spam rate >0.2%

❌ STOP IMMEDIATELY IF:
- Delivery rate <95%
- Bounce rate >5%
- Spam rate >0.5%
- Blacklisted

Rule #3: Consistent schedule

✅ GOOD:
Mon-Fri, same time daily (e.g., 10am)
Weekends: pause or reduce 50%

❌ BAD:
Random times
Skipping days
Sudden volume spikes

Rule #4: Quality content

During warm-up send:

• ✅ High-value educational content
• ✅ Personal, conversational tone
• ✅ Clear, relevant subject lines
• ✅ Strong CTAs (drive engagement!)

Avoid:

• ❌ Heavy promotional content
• ❌ Spam trigger words
• ❌ Too many links/images
• ❌ Purchased lists

GHL Warm-Up Workflow

Automated warm-up schedule:

WORKFLOW: "Domain Warm-Up Day 1"

TRIGGER: Daily at 10:00am

FILTER: Smart List "Warm-up Batch 1"
  - Max 50 contacts
  - Engagement score >80
  - Not emailed in last 30 days

ACTION: Send email "Value Content #1"

WAIT: 24 hours

TRIGGER: Next workflow "Day 2"

Create 30 workflows (Day 1-30), each increasing the batch size.

Dynamic batch sizing:

Custom Field: warmup_day = 1

If warmup_day = 1 → send to 50 contacts
If warmup_day = 5 → send to 250 contacts
If warmup_day = 10 → send to 800 contacts
Etc.

Increment warmup_day each day.

Monitoring Reputation

Google Postmaster Tools

Dashboard shows:
- Domain reputation: Low / Medium / High
- IP reputation: Bad / Low / Medium / High
- Spam rate: % of users marking as spam
- Feedback loop: User-reported spam

GOAL: "High" reputation within 30 days

Setup:

1. google.com/postmaster
2. Add your domain
3. Verify DNS record
4. Monitor daily

MXToolbox blacklist check

mxtoolbox.com/blacklists.aspx

Check weekly:
- Domain not on blacklists
- IP not on blacklists

If blacklisted:
- Stop sending immediately
- Request removal (provide details)
- Fix root cause
- Resume warm-up from Day 1

SenderScore (Return Path)

senderscore.org

Score 0-100:
- 90-100: Excellent ✅
- 70-89: Good
- 50-69: Poor ⚠️
- 0-49: Critical ❌

Check weekly during warm-up.

Troubleshooting Warm-Up Issues

Problem: High bounce rate (>5%)

Cause: Bad email list quality

Solution:

1. STOP sending
2. Clean list (email verification service)
3. Remove all bounced emails
4. Restart warm-up from Day 1 (lower volume)

Problem: Low open rate (<15%)

Cause: Landing in spam or poor subject lines

Solution:

1. Check spam folder placement (send to test accounts)
2. Improve subject lines (remove spam words)
3. Send to even more engaged contacts only
4. Reduce volume 50%

Problem: Blacklisted

Cause: Too aggressive, spam complaints, bought list

Solution:

1. STOP all sending
2. Identify blacklist (MXToolbox)
3. Request removal (explain situation)
4. Wait for removal confirmation
5. Restart warm-up VERY slowly

Problem: ISP blocks (Gmail/Outlook rejecting)

Cause: Volume increase too fast

Solution:

1. Pause 48 hours
2. Resume at 50% lower volume
3. Slower progression (2x/week instead of daily increase)
