What Are Email Sending Limits?

No one likes limitations, right? But sometimes, it’s important to set limits. Email sending limits are a common hurdle email users face, especially business owners. While email limits are important and there’s not much you can do to remove them, keeping a note of them can help. 

But if you do email outreach, you need to know the hourly or daily email sending limits set by your email hosting service provider. Never try to send bulk emails of more than 500 emails for cold email campaigns without knowing your email sending limit because it might block you for 24 hours to send any further emails. This might lead to delay in sending emails and thus loss in your business.

Today, we’ll talk about email sending limits, why they exist, why you should remember them, and which email hosting service to use to get the maximum email sending limit.

Email Sending Limits Explained

Email sending limit refers to the number of emails you can send or receive from your email account in a specified time period. Different email services have varying email limits. But in most cases, email services use per-day limits, along with limits for a shorter time frame. This could be per minute, per 10 minutes, per 30 minutes, or per hour. 

The question that arises is, why do email providers have limits on sending and/or receiving emails? Email limits are essential to ensure smooth and timely delivery of all emails, thereby providing a reliable service experience to all email users. 

Emails work on servers. Sending too many emails in a short period will increase the traffic, and thus, the load on the server. This increased load can lead to downtimes and delayed delivery. 

To avoid overload and server downtimes, email providers set limitations on sending and receiving emails. Essentially, the limit imposed by an email provider depends on its server capacity.

To send your email campaigns as per your plan and make it smooth, setup the delivery time of your emails as per the sending limits set by your email service provider. This way, your emails won’t be counted as SPAM unless you are sending low quality content having no personalization.

Therefore, best way is to plan your email campaign in such a way that you roll out series of email for a particular campaign split between few days. For example, send the first email on Day 1, the next one on Day 4, and the last one on Day 7. This way, you won’t have to worry much about the email limits.

Why Should You Be Aware of Email Sending Limits?

If you use email for business, you’re likely using email hosting service. When you send campaign emails in bulk from such providers, you may forget to keep the email limit of your email service provider in check. If you send too many emails in a short period, you’ll hit the limit, which might result in your account being blocked for 24 hours.

Also, the emails you send after hitting the limit will go to the SPAM box. This will increase your spam count, and your email address will be at risk of getting blacklisted. Moreover, the limits on automated emails are comparatively stricter, so it’s better to keep an eye on the sending limits.

When you know the daily and timely limits, you can schedule your campaign emails accordingly. This way, you’ll be able to ensure every email you send lands in your recipients’ inbox. 

Another important thing to keep in mind is that email limits are applicable to all types of emails. This includes new messages, replies, forwarded emails, and follow-ups. Therefore, it’s also critical to schedule your replies and follow-ups accordingly.

Email Sending Limits of Free Providers

Every email provider has a sending limit, but the limit is comparatively smaller for free providers. These limits are set so that online marketers don’t use bulk emails for promotions to send irrelevant emails to users. Here are the email sending limits of a few free email services. 

  • Gmail: 500 per day via SMTP, 500 from browser
  • 300 per day from Outlook address
  • Yandex.mail: 500 per day
  • Yahoo Mail: 500 per day

Once you have crossed the daily SMTP email sending limits, then you need to wait for a minimum of 24 hours to send further emails from that server. So, what are your options if you are having a large email list to roll out your newsletter on a weekly basis to more than 5,000 subscribers who are eagerly waiting for your emails? You need to switch from the free email service provider to a high quality email hosting company that meets your daily email sending limits.

One more reason to switch to a business email is the fact that your recipients are going to take your emails seriously from a business domain email address. Believe it or not, but people tend to ignore emails coming from as they do not take it seriously.


Hitting your email sending limits, again and again, is not good for your business email account. Your emails will end up in spam, and the reputation of your email account will also decline. Crossing the limits too often can also lead to your account being blacklisted or blocked. So, keep an eye on the email sending limits of your provider.

Also, check out Eltris for a high-quality email hosting service with flexible email sending limits. You don’t have to worry about splitting the email list into smaller groups with Eltris email hosting. You can simply copy the list of emails in your mailbox and hit the send button.

Regardless of which email hosting service you use, your business will only grow bigger if you reach more and more people. Therefore, it is very important that all your emails reach the inbox of your recipients without any delay or getting bounced due to sending more than the daily email sending limit.
