What Are the Email Sending Limits of Various Email Service Providers?

Email communication remains important for personal and business use, often facilitating critical functions like marketing campaigns, team updates, and daily correspondence. However, if you send too many emails simultaneously, email service providers like Gmail and Outlook will stop your emails from leaving your inbox or landing in your prospects' inboxes.

The consequences of this can be significant, impacting your marketing campaigns, customer relations, or even daily business operations.

To maintain good email deliverability, one important factor to consider is staying within your email sending limits. Knowing these email send limits helps ensure you never exceed them, safeguarding your email account from risks that could negatively affect your campaign performance.

In this article, we will provide you with up-to-date information on the email sending limits of leading providers such as Gmail, Outlook, and Office 365. We will also delve into other popular services and offer actionable advice on how SendNow can help you manage your email activities effectively, never to hit those limits.

Let's get started!

What is the Email Sending Limit?

Email sending limits are rules established by email service providers (ESPs) like Gmail and Office 365. The reason for implementing these limits is straightforward: to deter spammers from utilizing these platforms for mass outreach.

The aim is to stop spammers from using these platforms to send a large volume of unsolicited emails. Without such limits, anyone could sign up for an email account and send out a massive number of spam emails before potentially getting banned, causing disruption and reducing the quality of the service for other users.

These email sending limits are essential for safeguarding the email experience for all users, both for personal and business communication. While most people using email for legitimate purposes may not have to worry about these limits, there are situations—especially for businesses or agencies handling multiple clients—where understanding and adhering to these limits is essential for successful cold email campaigns.

Why is it Important to Know the Email Sending Limits of Different Providers?

Understanding your email provider's sending limits is a key factor many marketers overlook, only to wonder later, "Why are my emails going to spam?" These sending limits determine how many emails you can send each day and affect the frequency at which they can be sent.

Adhering to these limits increases the likelihood of your cold emails landing in recipients' inboxes rather than being diverted to spam folders. Email campaigns involve a lot more than just sending out an initial email.

There are various stages to consider, such as the warm-up phase, follow-up emails, and nurturing sequences. These combined factors can quickly put you over your provider's established email sending limit. Hence, it's essential to know details like the "Outlook email limit per day" or "how many emails can I send at once in Gmail" to plan your campaigns effectively.

Another aspect to consider is the content of your emails. The goal is to offer valuable content that doesn't include spam trigger words. If your email appears spam-like and lands in a prospect's inbox, there's a risk of being reported. Accumulate enough of these reports, and your email account could even get blacklisted.

To avoid these pitfalls, we have assembled a list of the sending limits for some of the most popular email service providers on the market. You can optimize your email strategies and safeguard your account from penalties by staying informed.
