Case Study: Improving Email Deliverability with Email Warm-Up in Snov.io
A business aiming to launch a high-volume cold email campaign was struggling with low deliverability rates and emails landing in spam. To improve email reputation, inbox placement, and engagement rates, the company used Snov.io’s Email Warm-Up feature.
Challenges:
New domains and email addresses often have low trust scores, causing emails to land in spam folders.
Poor sender reputation led to low engagement, reducing campaign effectiveness.
Without a proper warm-up, email providers (Gmail, Outlook, etc.) flagged messages as suspicious.
Gradual Increase in Email Volume
Started with 5–10 emails/day, increasing progressively to 100+ per day.
Avoided sudden spikes that could trigger spam filters.
Email Interaction Simulation
Emails were automatically opened, marked as important, and replied to.
Engagement patterns mimicked natural conversations, increasing sender reputation.
Varied sending times and recipients to appear natural.
Spread across different email providers (Gmail, Outlook, custom domains).
Deliverability Monitoring
Snov.io dashboard tracked key metrics:
Inbox Placement: 100% after warm-up.
Spam Rate: Dropped to 0%.
Reply Rate: Increased due to improved reputation.
Results
Emails consistently landed in inboxes instead of spam.
Improved engagement and sender trust.
More recipients interacted with emails.
