Email Warmup

Email warmup is the process of gradually increasing your sending volume on a new or dormant email account to build a positive sender reputation. Email providers like Gmail and Outlook track how recipients interact with your messages. A new account that suddenly sends hundreds of emails looks suspicious and often lands in spam. Warmup solves this by sending a controlled number of emails each day, generating genuine engagement signals that tell providers your account is legitimate and trustworthy.

When you enable warmup on an account, the platform sends emails on your behalf to a network of real inboxes. These emails are opened, read, and replied to — generating positive engagement signals that email providers use to evaluate your reputation. The daily volume starts low (a handful of emails per day) and increases gradually over several weeks. Emails that land in spam are automatically moved to the inbox, training providers to trust your sending address. The entire process runs in the background with no manual effort required.

Track your warmup progress from the account dashboard. Key indicators include: daily emails sent, inbox placement rate (percentage landing in inbox vs spam), reputation score, and warmup stage. The platform shows your progress over time so you can see your reputation building day by day. A healthy warmup shows a steadily rising inbox placement rate. If your placement drops, the system automatically adjusts the daily volume to protect your reputation. Most accounts reach a strong sending reputation within 2 to 4 weeks.

For the best results: 1) Start warmup before you need to send campaigns — give your account at least 2 weeks of warmup before your first real send. 2) Keep warmup running even after you start sending campaigns. The ongoing engagement signals reinforce your reputation. 3) Do not exceed your provider's daily sending limits during warmup. 4) Ensure your domain has SPF, DKIM, and DMARC records properly configured before starting. 5) Avoid sending to purchased or unverified lists during the warmup period. 6) If you pause warmup for more than a week, expect to rebuild some reputation when you restart.
