Gmail, Outlook, and Yahoo don’t allow more than 500 cold emails per day. With a Google Workspace account, you can send up to 2000 emails. But that’s the limit.
To send 10,000 cold emails at once without landing in spam (and also make money with it), you need a strong cold email tool like Smartlead.
In addition, you need 68 secondary domains, 200 email accounts (3 email accounts per secondary domain) to send 10,000 email messages.
In this article, you’ll find:
Let’s dive in.
For this part, I am guessing you already have a primary domain and a few email addresses.
Example: our primary domain is Smartlead.ai, and its email addresses are firstname.lastname@example.org, email@example.com, etc.
If you don’t have a primary domain yet, buy one before going to the next part.
If you're thinking how to send bulk cold emails, the first thing you need is a cold emailing software, such as Smartlead. Smartlead lets you add unlimited email accounts, warm up, create cold email campaigns, set follow-ups, schedule bulk emails, etc.

Secondary domains are additional domain names that a business or individual gets to complement their main domain.
For example, our primary domain is smartlead.ai, but our secondary domains are
Secondary domains are vital in sending bulk cold emails for 2 reasons:
If you're thinking how to send 1000 cold emails or more, always split your bulk emails into batches—a max of 50 emails per address.
Let’s get into a little math to find the answer to this question.
You want to send 10,000 emails per day. If you can only send 50 emails per address, you will need 200 email addresses (simply 10,000 by 50) to send 10,000 emails.
Now, it’s recommended to create only 3 email addresses per secondary domain.
So, divide 200 by 3. You need 66 to 67 secondary domains. We always recommend buying one or two extra domains. So, buy around 68 secondary domains to send 10,000 mails.
Similarly, if you're wondering how to send 5000 cold emails, you will need 33 to 34 secondary domains and 100 email addresses.
To send 1000 cold emails, 6 to 7 secondary domains are enough with 20 email accounts.
Once you’ve the secondary domains and the 200 email accounts, add them to your cold email tool.

Warming up email accounts is a must to see success with cold emails, especially when you’re using new domains and sending 10,000 messages.
Warm up your new email accounts for at least 2 weeks before launching the campaign.
Here are resources to help you out with warm-ups:
For 10,000 messages, use a cold email tool with an AI-based warm-up feature.
Sending 10,000 cold emails is similar to sending 100 emails. The difference lies in the number of secondary domains, the lead list, and how you segment and schedule it.
Let’s dig in.
The easiest way to create a lead list is to get a cold email tool that comes with a contact list building feature.
For instance, with Smartlead, you can opt for this feature (Listkit integration) and create a targeted lead list with just a few clicks on the Smartlead app itself.
If you want to use a separate platform for creating an email list, you have the below options:
A database is a storehouse of info about potential customers. The information includes industry, contact details, company size, locations, and performance metrics. Using various filters, you can search these databases for potential customers that align with your ICP. Apollo.io is one of the most popular B2B databases. Here’s an article on How to use Apollo to create an effective email list
An email finder or scrapper is a tool designed to retrieve email addresses publicly posted on the internet. Popular email scrappers are Clay, GetProspect, Skrapp.io, Hunter.io, etc.
Here are a few more resources to come up with a lead list:
Note: Always verify the lists before launching campaigns. Use Usebouncer, Bulkemailchecker, and MillionVerifier to verify the contacts.
Organise the downloaded lead list on a Google sheet or Excel doc using various columns to segment it properly.
Now, log in to the Smartlead app and click on the ‘Email Campaign' section from the navigation menu.
On Smartlead, you can either upload the lead list as a CSV file or import it directly from your CRM.
Next, connect each CSV column to the right dropdown option. If you have extra fields, like "Custom First Line," choose "Custom" in the dropdown. This way, you can include specific info not covered by the standard fields, making your data more personalised.
Afterwards, you will see a pop-up with a summary of the contact list, as shown below.
This summary is extremely crucial for bulk email outreach. Go through it and see if anything needs your attention.
Once you click “Save & Next”, you will go to the next step—sequences.
This is where you write the email body, subject line, and set the follow-ups for your 10,000-leads cold email campaign.
When writing the email body, check out the “spam checker” section on Smartlead. It will show the words or terms that are likely to alert spam filters.
Go through the results and improve your email copy accordingly.
Even though you’re sending 10,000 messages, it’s important to follow up to get the best results.
Here’s how we follow up at Smartlead.
Don’t set more than three follow-up emails. Keep a healthy interval between each follow-up email.
Once done creating the email sequence, choose the email accounts you want to send from. In this case, you need 200 email accounts for sending 10,000 messages.
That’s it. You’ve launched a 10,000-leads campaign successfully. Now, sit back and check the analytics dashboard on your cold email tool.
Sending 10,000 cold mails is no different than sending 100 messages. The practices remain the same. If anything that changes is the number of secondary domains and email accounts used for that particular campaign.
If you’re a beginner, I recommend starting small. It will help you understand cold emailing as a process and provide a chance to gain a better understanding of your target audience.
For beginners, 10,000 might be an overwhelming volume. But, if you still want to give it a shot, go ahead.

Always verify lists using tools like Usebouncer and MillionVerifier before the campaign launches.

No, sending cold emails is not illegal. However, laws and regulations like the CAN-SPAM Act and GDPR regulate cold outreach, requiring accurate information, protection of recipients' data, and application of an unsubscribe link within emails to comply with its provisions.
The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.
A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!
Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
