If you are going to send more than 10 emails per day, then yes, you do need to warm up your email accounts.
Why? Because it will help you to,
- Avoid spam filters
- Builds sender reputation
- Ensures consistent inbox placement
Ideally, you should warm up your domains for at least 2 weeks before you start increasing your daily sending limit.
PS. Don’t use your primary domain for sending cold emails. You will regret it!!!!
It’s better if you use an alias.
