Your emails belong in the inbox. Not in spam.
Built for B2B sales teams and agencies that rely on cold outreach. EmailWarmup.app helps new sending accounts build trust before campaigns and helps damaged accounts recover step by step when emails already land in spam.
Everything your inbox needs to stay out of spam
Free extra slots with Gmail and Outlook
Connect an existing Gmail or Outlook account to the network and earn 2 extra warmup slots per account. More capacity, at no extra cost.
Real emails between real businesses
Your account exchanges genuine business emails with other companies in our network. Including replies, opens, and marking as important.
Reputation score per provider
See not just your overall score, but how you perform at Gmail, Outlook, and Yahoo individually. Know exactly where to focus.
Emails rescued from spam
When warmup emails land in spam, the system moves them back to the inbox and marks them as important. Your placement improves every day.
Email authentication check
SPF, DKIM, and DMARC are verified daily. If something is misconfigured, you'll know before it causes problems.
Blocklist monitoring
We scan more than 10 blocklists every day. If your domain appears on one, you get an alert right away.
How it works
Whether you're warming up a new account or recovering a damaged reputation — the process is the same.
Connect your email account
New address or an account already stuck in spam — doesn't matter. Connect Gmail, Outlook, or your own domain and the system gets to work.
The system warms up and repairs
Every day, emails are sent, opened, replied to, and rescued from spam. For damaged accounts it takes longer, but the system works on it around the clock.
Your reputation stays protected
After warmup, it doesn't stop. The system stays active at low volume to keep your reputation warm. Without maintenance, your score drops right back down.
