Start your cold email campaigns the right way — by warming up your inbox with Sequence-R. Our free email warmup tool builds your sender reputation automatically, so your emails land where they should: in the inbox.

Why Warm Up Your Email?
Email providers don’t trust brand-new or inactive inboxes. Without a warmup, your cold emails are likely to go straight to spam.
Sequence-R helps by:
- Slowly increasing your sending volume over time
- Exchanging real emails between verified accounts
- Auto-replying to simulate genuine conversations
- Monitoring your domain reputation and inbox placement
How It Works
- Connect your inbox (Gmail, Outlook, custom SMTP, etc.)
- Choose your warmup pace — or let us handle it automatically
- Let it run in the background while you focus on prospecting
- Track results from your dashboard in real time
No setup headaches. No extra cost. Just better deliverability.
Who It’s For
- B2B founders launching outbound campaigns
- Freelancers and consultants using new domains
- Agencies managing outreach for clients
- Sales and marketing teams scaling up cold email
