What Is Email Warmup and How to Use It in EmaReach

What is email warmup?

Email warmup is the process of gradually increasing the volume of email sent from a new or unused inbox so that providers (Gmail, Outlook, etc.) learn to trust it. If you send a lot of mail suddenly from a new address, it can be flagged as spam. Warmup sends a controlled amount of mail (often to internal or partner addresses) and builds a positive sending pattern so your real campaigns land in the inbox.

Why EmaReach has warmup

EmaReach’s Warmup feature (available on supported plans) helps you warm up Gmail and SMTP inboxes before you use them for campaigns. The Warmup page in the sidebar shows which inboxes are warming, their progress, and lets you start, pause, or resume warmup.

How to use warmup in EmaReach

1. Go to Warmup in the sidebar.
2. You will see your inboxes (Gmail and/or SMTP) and their warmup state: not started, warming, paused, or complete.
3. For an inbox that shows Warm up required or Start warmup: click Start or Enable warmup so EmaReach begins the warmup sequence for that inbox.
4. Warmup runs over time (days to weeks depending on the curve). You can see progress (e.g. a percentage or chart) on the Warmup page and in Inbox Accounts (warmup status per inbox).
5. When an inbox reaches a sufficient warmup level, its status in Inbox Accounts will change to Ready or Warming (safe to use within limits). You can then use it in campaigns.
6. To pause warmup: use the Pause control on the Warmup page or in the inbox’s settings. To resume, click Resume.

Best practices

• Start warmup for new inboxes before sending campaigns from them.
• Do not send large campaign volume from an inbox that is still in "Warm up required" or early "Warming".
• Use the recommended send limits shown for warming inboxes if you send from them during warmup.
• Keep warmup running until the inbox shows Ready (or your plan’s equivalent) for best deliverability.

Summary

Warmup builds sender reputation gradually. In EmaReach, use the Warmup page to start, monitor, and pause/resume warmup for each inbox so your campaigns have the best chance to land in the inbox.
