How Many Cold Emails Can You Send Per Day Before Going To Spam?

I recommend that you send 40 cold emails max per day per email address.

If you send more than 40, you risk “burning” your domain, which will cause all of your emails to go to the spam folder.

Some people argue that you can send more, even up to 100 cold emails per day per email address, but in my opinion, it’s a better long term strategy to be more conservative so that you always have great deliverability.

In this article, I will cover the following:

• What is the daily sending limit for cold emails set by ESPs?
• Can you avoid sending limits by using newsletter sending softwares?
• How many cold emails can you send in a day without getting flagged?

Disclaimer: To be clear, this article is specifically about cold emails (unsolicited emails). This article is not about sending marketing/newsletter emails to large email lists of opted-in recipients using services such as Mailchimp, AWeber or ConvertKit.

What is the daily sending limit for cold emails set by ESPs?

There are three main email service providers that people use to send cold emails:

• Google (Google Workspace / Gmail)
• Microsoft (Microsoft 365 / Outlook)
• Zoho (Zoho Mail)

If you have a paid Gmail email account, set up through Google Workspace, then you will be limited to 2,000 email sends per day.

If you have a paid Outlook email account, set up through Microsoft 365, then you will be limited to 1,000 email sends per day.

If you have a paid Zoho Mail email account, then you will be limited to 1,000 email sends per day.

Even though these email service providers have relatively high sending limits, I strongly advise you to not send more than 40 cold emails per day per email address.

There is a big difference between sending 1,000 emails per day to your company’s internal employee email accounts, and sending 1,000 cold emails in a single day to people that have not opted-in and are outside of your organization.

If you have a large list of leads that you want to send cold emails to, then you need to use a cold email sending software, such as Emailchaser. This will ensure that your emails avoid spam.

Cold email sending softwares (such as Emailchaser) allow you to connect your existing email accounts (Gmail, Outlook, Zoho etc) and then will send emails in a way that won’t get your emails marked as spam.

For example, if you have a list of 1,000 leads that you want to send cold emails to, you can create a “campaign” in Emailchaser, and then upload these leads to your campaign. Emailchaser will then email 40 leads per day until all 1,000 leads have been emailed. This keeps your daily email sending amount in the safe zone, so that you don’t get flagged by email service providers as spam.

You can scale your cold email campaigns by adding more than one email sender account to a single campaign. For example, in Emailchaser, you could add 10 email accounts to a single campaign, which would allow you to send 400 emails per day (assuming the max is 40 emails per day per email address).

Can you avoid sending limits by using newsletter sending softwares?

You cannot avoid Gmail, Outlook or Zoho sending limits by sending emails through a newsletter software (Mailchimp, AWeber, ConvertKit etc).

Even if you could, it would still be a terrible idea because all of your cold emails would go to spam. Do NOT send cold emails through services like Mailchimp or ConvertKit.

Newsletter softwares are built to send emails in bulk (typically in a single blast) to large lists of emails where the recipients opted-in to receive emails.

Cold email (unsolicited email) is the opposite, since the people that you are cold emailing have not opted-in to receive your emails.

The reason why this distinction is important is because it affects your deliverability.

Sending thousands of emails at the same time through a newsletter software to an already opted-in email list is fine. Email service providers can recognize that these emails are already-opted in, and can detect how the recipients react.

Blasting thousands of emails at the same time to a list that hasn’t opted-in will cause all of your emails to be sent to spam. The only safe way to send a high volume of cold emails without going to spam is to use a special cold email software such as Emailchaser.

How many cold emails can you send in a day without getting flagged?

You might be able to send 100 cold emails per day per email address without getting flagged as spam by email service providers.

However, I recommend that you only send 40 emails max per day per email address. This will ensure that you never end up on the wrong side of any email service providers.

If you are cautious, you can have an email address that sends 30 to 40 emails per day forever, and you will always land in the primary inbox.

If you are not cautious, and you try sending too many emails each day, then your domain and email account will eventually get “blacklisted” by email service providers, and you will then need to buy a brand new domain and start the process all over again.

I recommend that you send your cold email campaigns with Emailchaser because we designed the software to keep you out of spam.

Emailchaser automatically limits your campaigns to 40 emails sent per day per email address. But it allows you to scale infinitely because you can add an unlimited number of sender email accounts to a single campaign. So if you want to scale, simply connect more email accounts to your campaign. This allows you to send an unlimited number of emails without going over the 40 emails per day per email address limit.

Final thoughts

I recommend that you send 40 cold emails max per day per email address.

If you send more than this, you risk “burning” your email address and domain, which will cause all future emails to go to spam.

I also recommend that you only create one email account per domain. You can scale your cold email outreach campaigns by buying additional domains and creating a new email sending account on each domain. To learn how to do this, check out my article How To Safely Scale Up Your Cold Email Outreach.
