How SendGrid Warmup Works
From new domain to trusted sender in four simple steps.
Connect
Link your sending domain in under 30 seconds. No SendGrid API changes needed. Your existing setup stays exactly as it is.
Configure
Set your warmup volume and ramp-up pace. We scale your domain reputation gradually so inbox providers start trusting it before your campaigns hit volume.
Auto-Warm
Our 5,000+ real inbox network sends, opens, and replies to emails from your domain. That engagement builds the domain-level trust SendGrid's infrastructure does not create on its own.
Monitor
Track your sender reputation score, inbox placement rate, and blacklist status in your live dashboard. Get alerts before problems reach your campaigns.
Works With Your Entire Stack
Native integrations with all major email providers and sales tools — no configuration needed.

E-Warmup helped them to increase their email deliverability 🎉

Our outbound emails were landing in spam without us realizing it! E-Warmup helped us fix inbox placement and stabilize sender reputation. We saw a 38% increase in open rates within two weeks.

Managing multiple client domains was always risky with deliverability. E-Warmup gave us visibility across everything. We've seen up to a 2.1x increase in reply rates on outbound campaigns.

We thought our issue was bad email copies. Turns out, emails weren't even reaching inboxes. E-Warmup fixed that, and reply rates increased by 44% in the first month.
