Deliverability is an Engineering Challenge. We Solved It.

What is it
What is it An always-on, peer-to-peer warming network.
Lookalike Modeling
Lookalike Modeling Every account connected to SendScale joins our secure network. Our system automatically sends and receives emails in the background, mimicking perfect human behavior.
The "Rescue" Protocol
The "Rescue" Protocol If a warmup email lands in spam, SendScale automatically pulls it out, marks it as "Important," and replies to it. This teaches Google and Outlook algorithms that you are a VIP sender.
Deliverability is an Engineering Challenge. We Solved It.

Support at Scale

The logic
The logic Sending 500 emails from one address is a death sentence for your domain.
The SendScale Way
The SendScale Way We distribute your campaign volume across multiple sending accounts you set up automatically. If you have 1,000 leads and 20 inboxes, our engine routes 50 emails through each. You get massive scale; ISPs see safe, organic volume.

Done-For-You Infrastructure Setup

The Pain
The Pain An always-on, peer-to-peer warming network over hundreds of thousands of emails.
The Fix
The Fix \Select the Done-For-You path. We procure the domains, configure the encryption records, and set up forwarding. You get a "Digital Passport" that verifies your identity to spam filters automatically.

Monitor Deliverability in Real-Time

Don't wait for a bounce to know something is wrong. Our Health Score Dashboard monitors your open rates and domain reputation daily. If an account dips below the safety threshold, SendScale alerts you immediately so you can rotate it out before it impacts revenue.

1
Can I use my main company domain? Yes, but we strongly advise against it. SendScale makes it easy to set up secondary "sending domains" to protect your primary brand's reputation.
2
How long should I warm up? Our data suggests 14 days for optimal results. You can schedule campaigns to launch automatically once the warmup period is complete.
