Short answer: There is no single magic number for how many cold emails you can send a day, but the safe approach is to start low, grow slowly, and keep each inbox at a modest volume rather than blasting from one account. Sudden spikes and high volume from a single inbox look risky to inbox providers. To send more, add more inboxes rather than pushing one inbox hard.
Why limits matter
Inbox providers watch how much you send and how people react. A new inbox that suddenly sends a large batch looks suspicious and gets filtered. Keeping volume modest and steady protects your reputation, so your emails keep reaching the inbox.
How to think about volume
- Start with a small number per day on a warmed inbox.
- Increase slowly over days and weeks.
- Keep a single inbox at a sensible daily amount rather than maxing it out.
- To scale, add more inboxes and domains.
Signals that you are sending too much
- Open and reply rates drop suddenly.
- More emails land in spam.
- Bounces rise, often from a dirty list.
How to scale safely
- Warm up each new inbox before using it.
- Spread sending across several inboxes.
- Keep lists clean so bounces stay low.
- Watch your numbers and slow down if they worsen.
