Email Warming Basics
What Is Email Warming?
Email warming means you slowly send more emails from a new or unused account. This helps email providers trust your account. You want to look like a real person or business, not a spammer. At first, you send only a few emails. Then you add more each day or week. Doing this step by step helps you build a good sender reputation.
You can use email warm-up tools to make things easier. These tools send emails for you and sometimes reply to messages. They help your account look active and real. Using email warming keeps your emails out of spam folders.
Tip: Begin with a small number of emails each day. Slowly send more over several weeks. This helps you avoid sudden jumps that can hurt your deliverability.
Why Email Warm-Up Matters
Email warm-up helps your emails reach inboxes, not spam. If you skip this step, your emails might get blocked or marked as spam. Internet service providers watch for big jumps in email numbers. If a new account sends hundreds of emails at once, they may think it is spam.
Here are some reasons to warm up your email account:
New IP addresses or domains without warm-up often get flagged as suspicious by ISPs.
ISPs check your sender reputation based on your email history. If you have no history, your emails may get rejected or sent to spam.
Slowly sending more emails and sending to people who open them helps build trust.
Skipping warm-up can cause problems like spam folder placement, bouncebacks, and sending limits.
Monitoring tools, like Google Postmaster, help you track your reputation during warm-up.
When you use email warm-up, you lower your bounce rate and complaint rate. You also improve your deliverability rate. The table below shows some important metrics and their recommended levels:
Metric | Recommended Threshold | Explanation |
|---|---|---|
Sender Reputation Score | Above 89% | Good standing; below 70% risks ISP flagging or blocking. |
Bounce Rate | Below 3% | High bounce rates harm sender reputation. |
Complaint Rate | Below 0.1% | Above 0.5% risks blacklisting; low complaints protect sender reputation. |
Deliverability Rate | At least 90% | Emails reaching inbox; below 70% harms engagement and reputation. |
Initial Daily Email Volume | 500-1,000 emails | Gradually increase during warm-up to build trust with ISPs. |
You can see that keeping your sender reputation high and your bounce rate low is important for email deliverability.
How Email Warmup Works
You start email warm up by sending a small number of emails each day. You send these emails to real people who will open, read, and sometimes reply. Over time, you send more emails. This slow increase helps ISPs see your account as safe and trustworthy.
Automated email warm-up tools can help you with this process. These tools send emails, reply to messages, and even mark emails as important. They use AI to act like real conversations. This makes your account look active and helps you build a strong sender reputation.
Warmy’s AI-powered warmup tool, for example, increases your sending volume in a controlled way. It lets you choose how your emails look and who gets them. This helps you match your warm-up to your business needs. As a result, you get better inbox placement and fewer emails in spam.

You can also track your progress with key metrics. The tables below show how your deliverability gets better with a good email warm up process:
Metric | Improvement / Target Value |
|---|---|

Open rate increase | Up to 30% improvement within first month |

Metric / Parameter | Value / Improvement |
|---|---|
Inbox placement increase | Up to 30% improvement |
Open rate increase | Over 20%, up to 30% within first month |
Warm-up duration | 4 to 8 weeks |
Starting volume | |
Weekly volume increase | 10-20% incremental increase |

Note: Most experts say you should warm up for 4 to 8 weeks. This gives your account time to build trust and improve deliverability.
When you follow a good email warm up process, more emails reach inboxes, open rates go up, and complaints go down. This helps your business grow and keeps your sender reputation strong.
Building Sender Reputation
Role in Deliverability
Building sender reputation is very important for email deliverability. Email service providers check your sender reputation before placing your emails. If your sender reputation is good, your emails go to inboxes. Bad sender reputation means more emails go to spam folders.
You can see how sender reputation affects deliverability in these ways: High sender reputation means more emails reach inboxes and fewer go to spam. Good open rates and click-through rates show people care about your emails. Low bounce rates and few spam complaints help keep your sender reputation high. Using authentication protocols like SPF, DKIM, and DMARC makes you more trusted. Sending emails regularly and sharing good content helps your deliverability get better over time.
Email service providers use these things to decide if your emails are safe. If you skip warmup or send too many emails at once, your sender reputation drops. This can make your emails get blocked or ignored. You should always work on building sender reputation from the beginning.
Tip: Try using Google Postmaster Tools or Sender Score to watch your sender reputation and deliverability.
Avoiding Spam Filters
A good sender reputation helps you stay out of spam filters. Email service providers like Gmail, Outlook, and Yahoo check your sender reputation every time you send emails. They look at bounce rates, how people interact with your emails, and if you use authentication rules.
Here are some ways to keep your emails out of spam: - Clean your email lists often. Remove bad addresses and people who complain. - Send emails to people who open and reply to your messages. - Do not send emails to spam traps or use bad list management. - Slowly send more emails during warmup to build trust. - Use authentication protocols to prove who you are.
A real example shows why this matters. Spotify used email verification to lower its bounce rate from 12.3% to 2.1% in 60 days. This helped their deliverability go up by 34% and reach more users.
When you work on sender reputation, your emails reach the right people. You also keep your business safe from being blocked or blacklisted. Warmup and keeping your email list clean are important for a strong sender reputation and better deliverability.
Email Warm Up Process
Manual Warm-Up Steps
You can begin warming up your email by sending just a few emails each day from your new account. Start with about 10 to 20 emails daily. Slowly send more emails over a few weeks. This slow increase helps you build a good sender reputation. It also helps you stay out of spam folders. Always send emails to people who are real and interested. Use SPF, DKIM, and DMARC to show your emails are safe. Watch your open rates and bounce rates to see how your emails do. If you see lots of bounces, stop and clean your list. Warming up emails by hand lets you pick who gets your emails and when. But it takes a lot of time and work to do each step.
