Warmup Limitations & Important Factors

We do everything possible to help domains and IPs achieve and sustain strong reputations, but a 100% guarantee is not possible because certain factors lie outside our control. Reputation depends not just on warmup but also on live campaign practices.

Conditions where achieving or sustaining high reputation is not possible

Poor Sending Practices

Sudden spikes in volume, skipping warmup, or ignoring ramp-up stages

Can severely damage reputation overnight
Bad Data Quality

Lists with high bounces, spam traps, or purchased/unverified contacts

Triggers ISP filters and blocking
High Spam Complaints

User “Report Spam” actions will always hurt domain/IP reputation

ISPs track complaints heavily
Content Issues

Spammy subject lines, high image-to-text ratio, or non-compliant templates

Automatic filtering by content scanners
Blacklist/Blocklist Entries

If domain/IP is blocklisted, corrective action is required before recovery

Complete delivery blocking
Policy Violations

Sending in prohibited categories without compliance will result in filtering

Permanent reputation damage
Recovery Timeline
  • Bad Reputation Recovery
    1–6 months with warmup-only campaigns
  • New Domain Warmup
    Up to 30 days for strong reputation
  • No GPT Status
    10–15 days to high reputation
Critical Balance

Maintain 40–50% warmup sends relative to live sends.
