How Mailchimp and Mailgun Warmup Works
From cold domain to campaign-ready in four simple steps.
Connect
Link your sending domain in under 30 seconds. No changes to your Mailchimp or Mailgun account needed.
Configure
Choose your ramp-up pace and daily warmup volume. Start gentle if your domain is brand new, faster if you are switching platforms mid-campaign.
Auto-Warm
Our 5,000+ real inbox network sends, opens, and replies to emails from your domain automatically. Inbox providers start building a trust profile for your domain before your real campaigns launch.
Monitor
Track inbox placement rate, reputation score, and blacklist status in your live dashboard. We alert you if anything shifts before it affects your list.
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 🎉

I have been using different e-mail warm up services and E-warmup is the best in the game. I avoid spam at all cost because of these guys. Thank you so much for being there for me when my company needs you most.

Inbox placement from 63% to 99% in a short time, over experience with e-warmup is outstanding, i learnt how to use the warmup settings for fixing mails vs maintaining high deliverability vs warmup. I switched from smartlead’s warmup to here and got the result what i expected basically. Customer support was really helpful.

I have used other warmup tools, but the best thing about e-warmup is some extra features that were not available in the other tools. E-warmup shows accurate data on email health, bounce rate (which is not found on other tools). Also, their AI read emulation feature is great.
