How Many Cold Emails to Send Per Day

Sending cold emails is one of the most effective ways to reach potential clients, partners, or customers. When done right, they can drive significant results for businesses. But how many cold emails should you send per day?

In this article, we will explain cold email outreach, ensuring you get a clear idea about the average cold emails you should send per day, and tips to improve your cold email campaigns' success.

How To Determine the Number of Cold Emails To Send?

Determining how many cold emails to send per day involves a careful analysis of multiple factors.

Here's a breakdown of the key considerations you should take into account:

1) Your Target Audience:

Knowing your target audience is foundational. Before pondering how many emails you should send per day, it's essential to understand the size and characteristics of your audience. Are they a niche group, or are you targeting a broader demographic? A larger audience might warrant sending more emails, but there's always a balance between quantity and quality.

2) Your Email Deliverability:

Email deliverability plays a significant role in the effectiveness of your outreach. Even if you're sending a large number of emails, it's pointless if they end up in the recipient's spam folder. Monitor your deliverability rates and adjust the average emails per day you send accordingly. If you're noticing a dip in deliverability, it might be due to sending too many emails or the content being flagged by email service providers.

3) The Quality of Your Cold Emails:

While determining how many cold emails to send per day is important, the quality of those emails is paramount. An effective cold email is concise, personalized, and offers value to the recipient. Sending fewer, high-quality emails might yield better results than a large volume of generic messages. Always prioritize quality over quantity.

4) Your Budget:

Your budget will directly influence how many emails you should send per day. Email marketing platforms often have pricing tiers based on the number of emails sent or the number of contacts in your list. It's essential to balance your budget constraints and the outreach volume.

5) How Long You Have Been Sending Cold Emails:

If you're just starting with cold emails, it's advisable to begin with a smaller volume and gradually increase the average number of emails sent per day. This approach allows you to test the waters, gauge recipient responses, and adjust your strategy accordingly. In contrast, businesses that have been sending cold emails for a longer time have more flexibility in sending larger volumes, as they've likely fine-tuned their approach over time.

Tips to Increase Your Cold Email Sending Limit:

Boosting the number of cold emails you can send daily can enhance your email outreach efforts. However, it's essential to do so strategically to ensure your emails don't land in spam folders or get you blacklisted.

Below are some tips to increase your cold email sending limit effectively:

1) Start with an Email Warmup Service:

Before you ponder how many cold emails to send per day, consider using an email warmup service. Such services gradually increase your sending volume over time, mimicking regular email activity. This gradual increase helps build a trustworthy reputation for your email account, reducing the chances of your emails being flagged as spam.

2) Understand Daily Sending Best Practices:

It's not just about the average number of emails sent per day; it's also about how and when you send them. Establish a consistent sending schedule and avoid sending massive batches of emails at once. Spread out your email sending throughout the day. This enhances email deliverability and ensures that you don't overwhelm your recipients or email service providers.

3) Know Your ESP's Daily Sending Limit:

Every Email Service Provider (ESP) has a daily sending limit. This limit dictates how many emails you should send per day. It's crucial to familiarize yourself with this daily limit to avoid crossing it, as doing so can lead to temporary or even permanent suspensions. Regularly review your ESP's terms and policies to stay updated.

4) Use a Cold Email Tool:

A cold email tool can be a game-changer when strategizing how many cold emails to send per day. Tools like SendNow automate the email sending process, ensuring consistency in your outreach efforts. They also provide analytics to track your emails' performance, helping you fine-tune your approach for better results.

By following these tips, you can effectively increase your cold email sending limit without compromising the quality or deliverability of your messages.

What if I Send Emails In Excess of the Daily Sending Limit?

Exceeding your daily sending limit can lead to various challenges, affecting your immediate outreach efforts and your long-term email marketing strategy.

So, what exactly happens when you cross the boundary of how many emails you should send per day?

1) Immediate Bounce Back:

The most immediate consequence is that your emails may get bounced back. This means that once you cross the threshold of the average number of emails sent per day as set by your Email Service Provider (ESP), any subsequent emails might not get delivered.

2) Reduction in Email Deliverability:

Consistently sending more than your allowed limit can reduce your overall email deliverability rate. This implies that even if your emails don't bounce, they might land in the recipient's spam folder, diminishing the effectiveness of your outreach.

3) Temporary Account Suspension:

Most ESPs monitor how many emails you should send per day. If you consistently exceed this limit, it might raise red flags, temporarily suspending your email account. During this period, you won't be able to send emails, disrupting your communication.

4) Permanent Account Blacklisting:

In severe cases, especially if your excess emails are reported as spam by a significant number of recipients, your email account can get permanently blacklisted. This halts your current outreach efforts and can damage your brand's reputation.

5) The Strain on Relationships with Recipients:

Continually bombarding recipients with emails, significantly if they exceed the expected volume, can strain your relationships. It might make your communications appear less genuine and more spam-like, reducing the chances of your emails being opened or read.

To avoid these consequences, it's important to keep a close eye on how many cold emails to send per day and ensure you adhere to the limits set by your ESP. Implementing monitoring tools or using email management platforms can help track and manage your email volume effectively.

How Important is Email Sender Reputation?

Email sender reputation is a critical aspect of email marketing and outreach. Essentially, it's a score assigned to your email sending IP address by Email Service Providers (ESPs). This sender score determines whether your emails land in the recipient's inbox spam folder or get blocked entirely. But why is this reputation so important when considering how many cold emails to send per day?

1) Inbox Placement:

A high sender reputation ensures your emails reach the recipient's main inbox, increasing the likelihood of them being seen and read. On the other hand, a poor reputation can cause your emails to end up in the spam folder or not get delivered at all.

2) Avoiding Blacklists

Maintaining a good sender reputation keeps you off blacklists. Being blacklisted can severely hamper your email outreach efforts, as most emails won't get delivered.

3) Trustworthiness:

A good sender reputation signifies that your emails are trustworthy. Recipients are more likely to open and engage with emails from trusted sources.

4) Improved Engagement:

Emails from senders with a good reputation are more likely to be opened, read, and acted upon, leading to higher engagement rates.

What Impacts Sender Reputation?

Various factors influence your sender's reputation:

1) Spam Complaints:

If a significant number of recipients mark your emails as spam, it negatively impacts your sender's reputation. This is why it's essential to ensure the quality of your cold emails and avoid sending too many in a short span.

2) Email Bounce Rate:

A high email bounce rate, which means many of your sent emails are not getting delivered, can adversely affect your reputation. Regularly cleaning your email list to remove invalid addresses can help reduce the bounce rate.

3) Engagement Rates:

How recipients interact with your emails plays a role. If your emails are frequently opened, read, and clicked upon, your sender's reputation can be boosted. Conversely, consistently low engagement rates might harm it.

4) Unsubscription Rates:

A sudden spike in unsubscriptions can be a red flag, indicating that recipients no longer find value in your emails.

5) Email Volume:

Sending a large number of emails in a short timeframe can be seen as spammy behavior by ESPs. It's vital to spread out your email sending and adhere to the average number of emails sent per day recommended by your ESP.

6) Email Content:

The content of your email, including the subject line, message body, and attachments, can also influence your sender's reputation. Avoid using spam-trigger words or misleading content.


Cold emails are an essential communication tool for businesses. The key to successful cold emailing is understanding the ideal number to send each day, ensuring high-quality content, and maintaining a strong sender reputation. By adhering to best practices and being responsive to feedback, businesses can leverage cold emails to their advantage, fostering valuable connections and driving results.

Email sender reputation, often overlooked, can make or break your outreach campaigns. A strong reputation ensures your emails reach inboxes, fostering trust and increasing engagement. On the other hand, paying attention to best practices or exceeding daily sending limits can tarnish this reputation, hindering your email marketing efforts.

To navigate the complex world of cold emailing, it's crucial to be informed, stay updated with ESP policies, and continuously adapt to feedback. By doing so, businesses can maximize the potential of their cold email campaigns, building fruitful relationships and achieving desired outcomes.


1) How Many Cold Emails To Send Per Day Without Triggering Spam Filters?

To avoid triggering spam filters, it's advisable to start with a lower number, like 20-50 emails per day, and gradually increase as you monitor deliverability.

2) How Many Cold Emails To Send Per Day as a Sales Rep?

A sales rep should prioritize quality over quantity. On average, sending 40-100 well-crafted cold emails daily can produce optimal results without overwhelming potential leads.

3) How many cold emails does it take to get one response?

The response rate varies based on the industry and email quality. Typically, for every 100 cold emails sent, one can expect a 1-10% response rate, meaning 1-10 responses.

4) Can I Send 50, 100, 500, or 2000 Emails at Once?

While technically possible, sending large volumes at once can trigger spam filters. It's best to spread out sends and be mindful of your Email Service Provider's sending limits.
