Warmup emails are scheduled at 12:00 AM UTC every day. If you recently enabled warmup, emails will start sending after the next 12:00 AM UTC.
Checking Warmup Status
To verify whether warmup is working correctly, review your account's warmup analytics for the last 7 days:
Go to the Email Accounts dashboard
Click on the email account you want to check
In the right-side panel, review the daily warmup email graphs for the last 7 days
You can also check the "Warmup Emails" column in the Email Accounts dashboard to see the total number of warmup emails sent in the past week.
If no warmup emails have been sent after 24 hours, use the sections below to identify and resolve the issue.
Warmup Paused
Accounts are automatically paused when your free trial or Email Outreach plan expires. This also pauses the warmup and campaigns.
To unpause:
Go to the Email Accounts dashboard
Select all paused accounts
Click the three dots(…) in the top right corner
Click "Unpause selected accounts" to unpause all accounts
Re-enable warmup for your accounts in bulk
Important: An active Email Outreach plan is required to keep accounts active.
Warmup Enabled but Not Sending
If your accounts aren't paused but warmup still isn't sending after 24 hours, follow the steps below based on where you purchased your accounts.
For accounts purchased from Instantly:
Go to the Email Accounts dashboard
Filter by "All statuses > Has errors"
If accounts are disconnected, check for a "Subscription Canceled" badge next to the DFY/pre-warmed accounts. This indicates those accounts have been canceled, and warmup won't work.
If canceled: To restore canceled accounts, reorder them via Email Accounts → Add New → Done-for-you Email Setup → Existing domains.
If accounts are active but still not sending: Contact support for assistance.
For accounts not purchased from Instantly:
Go to the Email Accounts dashboard
Filter by "All statuses > Has errors"
If accounts are disconnected, click "Test domain setup" to verify your DNS records are configured correctly. Missing or incorrect DNS records (MX, SPF, DKIM, DMARC) can cause emails to bounce and accounts to disconnect
Warmup Disabled (Red Flame Icon)
Warmup is disabled when your accounts bounce warmup emails from other users in the Instantly warmup pool. This protects the quality of the warmup pool for all users.
For accounts not purchased from Instantly:
Before reactivating warmup, verify your DNS setup:
Go to the Email Accounts dashboard
Click 'Test domain setup' to verify DNS records are configured correctly
If DNS records are missing or incorrect, contact your email provider to fix them before proceeding
Once the DNS records are properly configured, you can follow the steps below to request warmup reactivation codes and enable the warmup:
Go to the Email accounts dashboard and click on the red flame icon.
Click 'Request Reactivation Code'
Check your email inbox for the reactivation code (sent to the same email address you're reactivating)
Enter the code and click Submit
Warmup will be re-enabled
Troubleshooting reactivation codes:
Can't receive the code? If you see the error "Couldn't send an email, please check if the account address is deliverable," your account is currently undeliverable. Use a verification tool to check the account status and contact your email provider to ensure it can receive emails.
Code shows as invalid? This happens when multiple codes are requested - each new request invalidates previous codes. Wait 5–10 minutes without requesting a new code, then request once more and use the latest code received.
For accounts purchased from Instantly:
If your Instantly-purchased accounts show a red flame icon, please contact support for assistance.
