Stop Landing in Spam. Build Sender Reputation That Actually Delivers.

Email warmup automation that gradually scales your sending volume while keeping deliverability above 95%.

You’ve built the perfect email sequence. Nailed the subject line. Timed the send perfectly. Then 60% of your messages land in spam folders, and nobody sees them.

Email deliverability isn’t about what you send—it’s about the reputation behind the address sending it. ESP algorithms watch how recipients interact with your emails, and new domains trigger instant red flags. Send too many emails too fast from a cold account, and you’re blacklisted before lunch.

Interceptly’s email warmup solves this by mimicking natural sending patterns over time. The system gradually increases your email volume while maintaining engagement signals that ISPs trust. You’re building credibility that keeps your messages in the inbox where they belong.

How Email Warmup Actually Works

Most sales teams don’t realize their sender reputation is tanking until campaigns start failing. By then, the damage is done, and recovery takes weeks.

Email warmup prevents this by establishing your domain as a legitimate sender before you start prospecting. The platform sends emails at gradually increasing volumes—starting with just a few per day, then scaling based on engagement metrics and delivery success rates.

These aren’t random test emails. The system creates realistic sending patterns: varying send times, different recipient domains, and natural reply rates. ISPs see an account that looks like a real person gradually ramping up activity, not a bot blasting thousands of messages.

Within 2-3 weeks, your sender reputation is established. When you launch actual campaigns, deliverability stays consistently above 95% instead of dropping into spam territory.

Why This Matters for Multi-Account Operations

Scale Without Reputation Issues

Running outreach at scale means using multiple email accounts to distribute volume. Smart strategy—except every new account starts with zero sender reputation, creating a significant challenge for high-volume operations.

Automated Warmup Across Unlimited Accounts

Interceptly's warmup automation handles this across unlimited email senders simultaneously. Add five new accounts, and the platform automatically begins warmup sequences for each. You're not manually managing warmup schedules across multiple domains.

Real-Time Monitoring and Adjustments

The system monitors deliverability metrics for every account in real-time, adjusting send volumes based on performance. If one account shows declining open rates, it automatically throttles back. If another performs well, it scales faster automatically.

Continuous Warmup That Never Stops

Email warmup isn’t a separate process you run before campaigns. It’s continuous maintenance that runs alongside your active outreach.

Even as you’re sending prospecting emails, the warmup system maintains sender reputation in the background. This is especially critical when sending high volumes. Our clients send up to 10,000 emails monthly per account while maintaining deliverability that most platforms can’t touch.

That’s 1,200 additional prospects monthly seeing your message. Your competitors lose deals to spam filters. You operate with infrastructure that ensures inbox delivery.
