Keep the mailboxes connected for a good reputation. There is no such thing as just "warming up" anymore.


There’s a common misunderstanding that you only need to “warm up” your mailbox for a short time and then you’re done. This idea comes from traditional email marketing, but in reality, warming up is not a one-time task—it’s about maintaining a healthy and natural email sending reputation over time. 


What Does “Warming Up” Really Mean? 


Your goal isn’t just to warm up a mailbox quickly. Instead, you want to bring your mailbox to a natural state by achieving a consistent and realistic average response rate that mimics genuine email conversations.


Mailivery helps you with this by combining your real email activity with its own warmup emails. This increases your total response rate, which signals to spam filters that your emails are normal and trustworthy. 

Why Is Response Rate Important?


A mailbox with a good reputation usually has an average response rate between 5% and 10%. On the other hand, cold outreach emails typically get only about 1% response.


Mailivery boosts your average response rate by sending warm-up emails and generating replies automatically. This helps your emails land in the inbox more often and avoids spam folders.


Your true goal is not to warm up a mailbox but to bring the mailbox to a natural state by means of a natural overall average response rate.


How Long Should You Warm Up?


If you want to just warm up your mailbox and don’t plan to maintain the activity afterward, you should warm it for 8 to 15 weeks. This will give your mailbox a better reputation, but keep in mind that if you stop, your reputation may drop again and you could end up in spam more often.


The best practice is to keep your mailbox connected to Mailivery consistently to maintain that natural, healthy response rate and keep your sender reputation strong. 


Summary:

  • Warming up is not a one-time task—it’s about keeping a natural sending pattern.

  • A healthy mailbox has a 5% to 10% response rate.

  • Mailivery helps you boost your response rate by adding real-seeming interactions.

  • For short-term warming, plan for 8 to 15 weeks.

  • For long-term results, keep your mailbox connected and active.
