Free Email Warmup Tool

Boost your email deliverability and avoid the spam folder — completely free.

Email warmup is the first step toward successful cold outreach. Sequence-R’s free email warmup tool automatically builds your sender reputation so your emails land in inboxes, not spam.

No credit card required. Start warming up in under 2 minutes.

Why Use an Email Warmup Tool?

When you send cold emails from a fresh or inactive inbox, email providers don’t trust it right away. Without proper warmup, your emails are more likely to end up in spam.

Sequence-R solves that by:

• Gradually increasing your email sending volume
• Sending real emails between verified accounts
• Automatically replying and engaging to simulate natural conversations
• Monitoring your reputation to keep deliverability high
