What are the Cold Email Sending Limits?

woman giving good tips - How Many Cold Emails Per Day

Cold email-sending limits are restrictions established by email service providers (ESPs) on the number of emails you can send within a specified period. These limits exist to help prevent spam and protect users from malicious attacks. When a user suddenly starts sending many emails, it raises a red flag. To mitigate this risk, ESPs impose cold email-sending limits.

Factors That Influence Cold Email Sending Limits

The number of cold emails you can send without hitting a sending limit depends on the ESP you use. Different providers enforce various rules and policies. For example, Gmail and Outlook have different approaches to cold emailing. In addition to the ESP, other factors can influence cold email limits. These include the type of account you use (personal vs. business) and the sender’s reputation. A new account will have a low sending limit, while an account that has been warmed up and used for legitimate purposes will have a higher limit.

How Many Cold Emails Can You Send Per Day?

When setting up cold email campaigns, the first question on every cold emailer’s mind is: “How many cold emails can I send per day?” The reason for asking this question is genuine; you don’t want to end up in the spam folder. That’s why we have created this guide.

Understanding Email Service Provider Limits: The Foundation for Effective Cold Email Outreach

We have answered how many cold emails to send per day and mentioned the most popular email service providers with their sending limits and prices. You’ll also find tips for sending cold emails without harming your sender’s reputation and learn about mistakes to avoid. Before discussing how many cold emails to send per day, it’s essential to understand the cold email sending limits set by the ESPs.

The Spam Limit: A Key Thing To Know Before Sending Cold Emails

You should know the imposed email sending limit and spam limit. In the table, we have mentioned the ESPs’ imposed email-sending limits; as per best cold emailing practices, NO ONE should send this many emails from one email account. You should always find the gray area where you can play safe. That’s why we came up with Spam limits. ESPs do not give spam limits, but we developed them after sending cold email campaigns for 7-8 years. So, what is the Spam Limit? A spam limit is a specific volume of emails sent. After reaching this limit, if you send more emails, they will start going to spam.

Maximizing Cold Email Efficiency: G-Workspace and Office 365 Spam Limits and Best Practices

We have given the spam limit for G-Workspace and Office 365 as they are the two most commonly used ESPs for cold emailing. Spam Limit for G-Workspace and Microsoft is 150 emails per email account. We recommend sending 150 emails per day, but not initially. This should only be done after warming up your account for at least a month. Our cold emailing experts also recommend creating 3-5 email accounts with 1 domain to protect the sender reputation of your domain.

Calculating Daily Cold Email Volume: A Formula for Scaling Outreach Safely

Now, you can use the number of email accounts and the spam limit to determine how many cold emails to send per day with this simple formula:

Cold Emails to Send Per Day = Spam Limit/Email Addresses in the Campaign

In this case, 150 / 3 = 50 emails. This means you can send 50 emails per day from one email account. However, once you have built a good sender reputation and hit 150 emails, you can gradually increase the number of cold emails over time. This means you can send 50 emails per day from one email account. Once you have built a good sender reputation and reached 150 emails, you can gradually increase the number of cold emails.

How Many Cold Emails Per Day Without Triggering Spam Filters?

email of a person - Email Sender Reputation

The number of cold emails you can send before being flagged as spam can vary. A common misconception is that there is a specific number of safe emails a business can send without them going to spam.

In reality, whether your messages end up in email spam folders or not depends on factors like:

Email content
Sender reputation (affected by both your domain and IP address)
Recipient engagement
Mailbox age
Domain age
Size of company you're prospecting (number of employees)

Crafting Effective Email Content: Balancing Volume and Presentation for New Domains

When we refer to email content, we mean the actual content of your email and how you present it. That is, whether you send multiple emails in plain text or carefully design HTML email templates for outreach. For example, a newer mailbox and domain can't send nearly as many emails as a warmed-up domain and mailbox. If you’re just starting, sending up to 10-20 emails daily is best.

Warming Up Your Email Address Before Cold Emailing

When you start your car, you don’t want to slam the gas and drive 100 miles an hour immediately, as that would hurt the engine. The same goes for email inboxes. You want to warm up your email address slowly over time. Otherwise, you will hit some spam folders if an email service provider sees you creating an address and spamming 100 emails on your first day.

Email warmup means sending emails gradually so that email providers see you as a trustworthy sender. You can do this manually or use an email warmup service instead. Also called an email warming service, these tools send emails to different addresses daily. This way, you get a kickstart to your cold emailing campaigns. An email warming service may cost a few bucks, but it’s worth it because your email account will be ready to use sooner rather than later.

Understand the Daily Sending Limit with Different Providers

Depending on your email service provider, you will be limited by a certain number of emails you send daily. Whether you’re sending to previous contacts or sending out cold email campaigns, it does not matter. The best advice we can give for a successful cold email campaign is to avoid free email providers. For example, the daily sending limit for a free Gmail account is 500 emails, while a paid one will get you 2,000 emails you can send per day.

Comparing Email Service Providers: Daily Sending Limits and Best Practices

Here are some other email service providers and their daily sending limits:

Google Workspace

Messages: 2,000 per day
Total recipients: 10,000 per day
External recipients: 3,000 per day

Google also imposes a maximum limit of 2,000 recipients per email (which decreases to 500 per email for external recipients).

Gmail

Messages: 500 per day
Total recipients: 500 per day

Google doesn't define hourly email limits. Limiting your emails to less than 20 per hour is best.

Microsoft 365

Messages: 30 messages every minute
Total recipients: 10,000 per day

It should also be noted that the maximum number of recipients who can receive a single message is 500.

Exchange Server

Messages: No limit
Total recipients: No limit

Exchange Online

Messages: 30 messages every minute
Total recipients: 10,000 per day

Outlook

Messages: 30 messages every minute
Total recipients: 5,000 per day

The above figures are for Microsoft 365 subscribers. Actual limits can be lower based on the age of the email account, how often the account is used, and subscription status.

Yahoo Mail:

Messages: 500 per day
Total recipients: Each email message can be sent to a maximum of 100 recipients

Rackspace:

Messages: No limit
Total recipients: 10,000 per day

Rackspace limits automated emails to a much lower amount.

GoDaddy:

Messages: 200 per minute and 300 per hour
Total recipients: 500 per day

Bluehost:

Messages: 150 per hour
Total recipients: No limit

Choosing the Right ESP: Managing Limits and Avoiding Spam in Cold Email Campaigns

You might notice your emails going to spam even after you've followed the sending limits of your email client. So, if you’re wondering how many cold emails to send daily, you should start with the email service provider you’re using. If you’re launching new cold email campaigns, choose your email service providers based on the daily volume you need to send.

Exceeding daily sending limits does not have negative consequences if you don’t do it too often. For example, Google Workspace will stop sending emails if you exceed this ESP’s daily sending limit. Others will postpone them until your time limit is up and then push them to a recipient’s inbox. However, try not to exceed this limit and send too many cold emails too often.

Your Sender Reputation Makes a Major Impact on Your Cold Email Campaigns

Sender reputation is like a credit score that email service providers give you based on your trustworthiness as a sender. The better your sender reputation, the more likely your cold emails (and other emails) will reach your recipient’s inboxes.

Here are some of the things affecting your sender’s reputation:

The number of bouncers.
The number of spam complaints you get from your emails.
Whether or not you hit spam traps when you send your cold email outreach.
Your email engagement – how many people open and respond to your cold email marketing campaign.
Email segmentation and personalization – whether you send tons of bulk emails or personalize cold emails.
The volume – how many cold emails you send out in a given period.

You must monitor all of these factors to maintain a positive sender reputation. And since many cold email campaigns entail blasting the same message to everyone, it’s no wonder they don’t lead to a good sender reputation.

How to Get a Better Sender Reputation

The factors that influence a sender’s reputation are well-known, making it easy to watch out for dangers and avoid spam folders. With a sold email sender reputation, you’ll have an easier time with your cold email efforts.

Here are some practical tips for keeping your sender reputation spotless:

Use email validation services and clean your email lists before sending out your next cold email campaign
Give your recipients an easy way to unsubscribe and include a link for it in your cold emails
Segment and personalize your cold emails
Use authentication protocols before sending out any cold emails

A good reputation won’t affect how many cold emails you can send. It will affect the success of all of your email marketing campaigns, so it’s worth keeping an eye on it.

What to Do If You Have a Brand New Email Account

If you have a new email address or multiple email accounts from which you want to send emails, you must take things easy and set yourself up for success. Otherwise, you’ll hit the spam filters on different mail servers and do more harm than good. Warm up your email account by sending a few emails daily and gradually increasing the number. You can also use an email warmup service to speed things up. Once you have an email list from a reliable scraper or email tool, don’t blast out a cold email campaign. You want to make sure the email list does not have invalid addresses, outdated ones, addresses with typos, spam traps, and more.

3 Ways To Reduce Your Spam Rate

1. Segment Your Email List

Always segment your email list and focus your mass email outreach into smaller, more targeted groups of prospects based on triggers. This way of sending personalized emails is great for increasing your inbox placement and engaging any email recipient. Why? Hyper relevance.

Hyper relevance involves going beyond the usual segmentation criteria for personalized emails like:

Industry
Job roles
Age
Location

Instead, you'll want to establish the right time to reach out. You can do this using data sources like:

What does the prospect engage with on social media?
Changes to tech stacks within companies.
Product reviews left by prospects on platforms like G2.

Using Data and Segmentation for Personalized Email Campaigns That Drive Engagement

Gathering and understanding this data can help you extensively segment your email list and send personalized emails. Your emails will be sent to contacts from your mailing list who are more likely to need your product or service—reducing your spam complaint rate. Use account-based marketing (ABM) tactics to ensure you land in the inboxes of companies that other departments (like marketing/sales) are also focused on targeting and engaging.

ABM Cold Emailing Best Practices: Managing Limits and Engagement Metrics

While conducting cold outreach on ABM, you'll explore creating additional limits to avoid saturating those accounts with cold emails.

Minimum Spacing: The minimum time gap between sending an email to another contact at the same account.
Active Contacts: Number of contacts who can be emailed within 30 days.
Unenrollment Trigger: The trigger to remove a contact from your email cadence due to their unresponsiveness.

2. Avoid Third-Party SMTPs and Alias Emails

Many people use alias emails to centralize their incoming emails. It's a great way to receive messages from multiple email addresses in a single inbox. The issue arises when businesses use alias email addresses to send outbound emails. When you send outbound messages from alias email addresses, the account that sends the email and the account mentioned in the From field differ. Because of this, spam email senders often use alias email addresses to distribute spam email campaigns several times under various names, using one email license. This can put the email service provider on ‘high alert’ and make it more likely for your messages to end up in spam email folders.

Understanding SMTP Providers and Their Impact on Cold Email Deliverability

Third-party SMTPs can also reduce your cold email inbox placement rates. They use services like SendGrid and AWS, which are designed for an opt-in mailing list and bulk email marketing campaigns to subscribers. Since these third-party SMTPs can send far larger volumes of emails within a short time frame, every email service provider tends to scrutinize them thoroughly. This can, in turn, affect your campaigns—putting them in a spam folder more often.

Use Inframail

While trying out the tips we've covered can help you reduce your spam rate to a certain degree—pairing them up with an email deliverability tool will give you the best results. At Inframail, we are revolutionizing cold email infrastructure with unlimited inboxes at a flat rate.

Forget the Technical Headaches: Automated SPF, DKIM, and DMARC Setup

These acronyms sound intimidating, but they're crucial for email deliverability. You can think of SPF, DKIM, and DMARC as the security guards of your email reputation. They help determine whether your emails are actually from you or an impersonator and help protect your domain from being used by hackers. Setting these up manually is a significant pain and can take hours. Inframail automates the process so you can focus on what matters—crafting great emails that get replies.

3. Fortify Your Outreach With Dedicated Email Servers

When you create email accounts with traditional providers, you share an IP address with hundreds or thousands of other users. If any of these users get blacklisted for spammy behavior, it can hurt your deliverability, too. Inframail gives each user their dedicated IP address to ensure you don't suffer from someone else's bad reputation. This setup is crucial to scale your outreach and stay under the radar.

16-Hour Priority Support to Scale Your Outreach Efforts

Dedicated Email Servers to Enhance Deliverability

In addition to the automated setup, Inframail’s dedicated email servers for each user ensure you can cold email at scale without being flagged for spam.

With Inframails email infrastructure, you won’t share your server with anyone else. This minimizes the risk of deliverability issues, so you can email who you want when you want.
