So, if you’ve ever wondered, “What’s the best way to send bulk emails?”  This guide is for you.

Let’s get started.

How to Send Bulk Emails in 5 Different Ways?

This section covers all the possible (and legitimate) ways to send bulk emails in 2025. Make sure to follow them step by step so that you don’t encounter avoidable issues.

Also, don’t forget to check the “Best for” section in every method. I’ve explained which method works best for which use case, so you don’t end up picking the wrong one and wasting your time.

Method 1: Send Bulk Emails with the BCC Method

One of the easiest ways to send emails in bulk is through the BCC method.

It stands for blind carbon copy functionality, which is available in every email service provider, be it Gmail, Outlook, Yahoo, and others.

When you add your recipients in the BCC field instead of the To field, none of them will be able to see each other’s email addresses.

Now, depending on which platform you’re using, your sending limit may vary.

Here’s a quick overview of popular ESPs and their daily sending limits :

However, I will be showing you how to send bulk emails in Gmail using the BCC method. But the steps are the same for all the other email service providers.

Step 1: Create Multiple Email Accounts (Mandatory Step)
Step 2: Click on the Compose Button & Write Your Email Copy
Step 3: Add Your Recipients
Step 4: Hit Send

1. Create Multiple Email Accounts (Mandatory Step)

Gmail takes email sending rules seriously because it wants to protect its users from spam.
So even if you’re following the daily limit, sending a large number of emails every day can still get your account blocked.

To avoid that and keep your domain safe, it’s better to use multiple email accounts and send only 50 to 100 emails from each one per day.

2. Click on the Compose Button & Write the Email

Log in to your Gmail account> click on the “Compose” 🖊 icon and write your email.

Don’t forget to add all the relevant details in the email and keep it short under 100 words.

3. Add Your Recipients

Add your email in the “To” field and all your prospects in the “BCC” field. Make sure you add around 20-30 recipients in one email campaign.

4. Hit Send

Once you are satisfied with your email copy, hit the send button.

Method 2: Send Bulk Emails with Built-in Mail Merge in Gmail

Another way to send bulk emails is by using Gmail’s built-in mail merge feature.

Now, just a heads-up, you can only access this feature if you’re using a paid Gmail account (Google Workspace). 

Why is this method better than the BCC method?

Gmail will send one email to each person on your list.

Their email will show up in the “To” field, and they won’t see who else got the email.

This will help you to send bulk emails by hiding the recipients.

To send emails using mail merge in Gmail, you can either use the direct method or use a spreadsheet.

The spreadsheet method works kind of like Outlook mail merge, which I’ve explained in the next section.

Therefore, I will be explaining the process of adding recipients directly to your message !

Step 1: Get a Google Workspace Account
Step 2: Create Your Contact List
Step 3: Start a New Email and Enable Mail Merge
Step 4: Write Your Email
Step 5: Preview and Send

Let’s decode it in detail!

1. Get a Google Workspace Account

First of all, you need to buy the Standard or above pricing plan of Gmail.

 It’s only available with Google Workspace (Business Standard plan or above), which starts at around $14/month/user.

2. Create your Contact List

Now go to Google Contacts and click on “Create label”. Name it (e.g., “July Campaign” or “Client List”)

While you are adding contacts to the label, make sure that for each contact you have added:

• First and last name
• Email address

Or you can add any other fields you want to use for personalization.

P.S.: When adding information under the label, ensure the information is correct, as Gmail directly pulls it from that list to personalize.

3. Open a New Email and Click on the “Compose” Button on the Top Left

Now, click on the three dots and from the drop-down menu select “mail merge.”

In the “To” field, enter the label you created (e.g., “July Campaign”)

4. Write Your Email

In the email container, compose your email like email copy, subject line, and use placeholders for personalization.

5. Preview and Send

Click on the Preview button to check if the placeholders are working.

If everything looks good, press Send!

Method 3: Send Bulk Emails with Mail Merge in Outlook

Over 400M+ people use Outlook, and if you are also using it (I won’t judge you!), you’d be happy to know that you can send bulk emails in Outlook too!

Unlike Gmail, you don’t have to pay extra to access the mail merge feature. Outlook lets you use it for free.

That said, I do want to highlight one thing — mail merge isn’t available on the Outlook web app. You’ll need to use the Outlook desktop app to access it.

Step 1: Prepare Your Email Copy
Step 2: Set Up Your Recipients List
Step 3: Link Your Recipients List to Your Email Message
Step 4: Add Personalized Content to Your Email
Step 5: Preview and Finish Mail Merge

Let’s explore the steps!

1. Prepare Your Email Copy

First, you need to go to Word, and on the tab click on “Mailings” > “Start Mail Merge” > “E-mail Messages.”

Now you can compose your email and add placeholders like {{Name}}, {{Company}}, etc., where you want to add your recipient’s details.

Once done, minimize the document tab (don’t save or close it). 

2. Set Up Your Recipients List

Alright, now head to MS Word and open a new workbook.

Fill in the important information, such as first name, last name, and email address, in the sheet.

Now, save it.

Pro tip: Double-check the information and make sure it is placed in the right columns because if something’s wrong, it won’t merge correctly!

3. Link Your Recipients List to Your Email Message

Click on “Select Recipients” > “Use an Existing List,” then choose your email list and upload it.

4. Add Personalized Content to Your Email

Now go to “Mailing Tab” and click on “Greeting Line” to add the personalized opening line.

After this, click on “Insert Merge Fields” to automatically add all the merge tags to the email.

And replace the placeholders with the correct merge tags in your email. 

If you skip this, your emails won’t be personalized correctly!

PS: If you want to change the font, size, or spacing of the merged content, select the merge field name and make the required changes.

5. Preview & Finish

Click on the “🔍” icon to preview your email. 

Once everything looks good, click on “Finish & Merge” > select “Send E-mail Messages.”

A pop-up will appear with the following options:

• In the Subject line box, write the subject line for your email.
• Under the Mail format section, you can choose how your email will look.
  You can select from:
  • HTML (which is the default and lets you add formatting like bold text, links, etc.)
  • Plain text if you want to keep the email simple with no styling
• Then, under Send records, you’ll see three options:
  • All records (Default setting) – This sends the email to everyone on your list.
  • Current record – This sends the email only to the person currently visible on your screen.
  • From and To – This lets you choose a specific range of people from your list (for example, from person 5 to person 20).

Choose “OK” to run mail merge.

How Much Does It Cost to Send Bulk Emails?

The cost of sending bulk emails depends on two major factors:

• Email Infrastructure Cost (sending domains & email accounts)
• Automation Platform Cost (if any)

1. Email Infrastructure Cost

As per most successful cold emailers, you should send 30-50 emails daily from an email account.

Now, it is also recommended to keep separate sending domains so that you don’t ruin the sender reputation of your primary domain.

Domain cost: $10-$15 per domain per year.
Email account cost: $3-$5 per account per month.

2. Automation Platform Cost

If you are planning to use an email automation platform (for marketing or emails), it will have different charges based on the monthly emails and active prospects.

• For sending bulk cold emails, it can cost around $60-$80 for sending 10,000 - 20,000 emails every month.
• For sending mass marketing emails, it can cost you around $20-$40 per month for every 10K emails.

Best Tips for Sending Bulk Emails

Follow these simple practices to send bulk emails the right way and avoid landing in spam folders or getting your domain blacklisted.

Tip 1: Comply With Regulations
Tip 2: Maintain Deliverability
Tip 3: Segment Your Leads for Targeted Personalization
Tip 4: Follow a Sending Pattern

Let's get into the details!

Tip 1: Comply With Regulations

Before sending bulk emails, ensure you adhere to relevant email rules, such as the CAN-SPAM Act in the U.S. and the GDPR in Europe.

Why?

Well, if you break these rules, you could face hefty fines in the tens of thousands per email under CAN‑SPAM, or even up to 4% of your annual revenue under GDPR. 

Tip 2: Maintain Deliverability

When sending bulk emails, ensure you maintain high deliverability rates. 

Because if your deliverability is poor, even the most perfectly written email won’t reach your audience. 

And it will not only end up wasting your efforts, but also hurt your domain reputation.

Here is how you can achieve maximum email deliverability →

• Set up SPF, DKIM, and DMARC
• Warm up your domain 
• Avoid spammy content
• Stick to a steady sending schedule
• Include an unsubscribe link

Tip 3: Segment your Leads for Targeted Personalization

If you are sending bulk email campaigns for sales or outreach purposes, don't dump all your recipients into the same list.

Because it will not get your results!

Instead, segment your leads based on their pain points or use cases. 

Once you do that, use those insights to personalize your emails more meaningfully.

Why is targeted personalization important?

Well, it’s 2025, and personalization isn’t just about adding someone’s name or company anymore.

These days, if you want replies, you’ve got to go beyond the basics.

Targeted personalization makes your email feel relevant and shows the reader that you actually understand them and their challenges, not like some random stranger showing up in their inbox.

Tip 4: Follow a Sending Pattern

Timing is important when it comes to sending bulk emails!
And sticking to a proper sending pattern not only helps you to avoid spam filters but also gets more engagement. Therefore, here are some tips that you can keep in mind while creating a sending pattern for your bulk emailing campaigns.

• Don’t send all your emails at once; space them out in batches
• Choose fixed days and times instead of random blasts
• Maintain gaps between follow-ups so you don’t come off as spammy.

Pro Tip:

• Send bulk emails on Tuesdays, Wednesdays, and Thursdays between 10 AM to 1 PM
• Do not send emails late in the evening, during weekends, or early Monday mornings

Common Mistakes to Avoid While Sending Bulk Emails

Here are some common mistakes to avoid while sending bulk emails that can hurt your efforts:

• Buying Email Lists From Unreliable Sources
• Ignoring Bounce Rates
• Sending Bulk Emails from a New Account

Let's decode them!

1. Buying Email Lists From Unreliable Sources

I’m not saying buying email lists is wrong, but where you buy them matters a lot.

If you get your list from an unreliable source, there is a high chance that the emails in it will be outdated or fake. 

That means you’re not just wasting money, but you’re also putting your domain at risk.

2. Ignoring Bounce Rates

You should always keep an eye on the Bounce rates!

Because high bounce rates can seriously hurt your bulk email campaigns by causing things like:

• Email providers will see you as a spammer
• It will damage your sender's reputation
• Affect the deliverability of future emails

Therefore, to avoid high bounce rates, make sure you remove invalid emails from your list and make sure your list is always clean and up to date.

3. Sending Bulk Emails from a New Account

If your email account is new, don’t use it for bulk emailing right away. 

As email service providers can easily recognize new accounts that suddenly start sending hundreds of emails, which triggers their spam filters. 

So, what should you do instead?

Before using your email account for bulk emailing, warm it up. First, start by sending small volumes, as it will slowly build trust, and then increase the number of emails over time.

Choose the Right Method to Send Bulk Emails

Bulk emailing is still one of the most effective ways to communicate with a large group of people, be it for sales, updates, or announcements.

But it only works if you’re using the right method.

In this guide, I have shared all the ways to send bulk emails, along with their pros, cons, and when to use each one.

So, now it’s your turn to figure out which one fits your requirements.

Here’s what I suggest:

Don’t overthink it. Just pick one method and start with a small campaign, and figure out what works.

FAQs

1. Is it possible to send 10,000 emails at once?

10,000 emails is a big number, but it’s actually scalable if you use a cold emailing platform with all the email deliverability and personalization features so that you get replies from your emails.

You can use Saleshandy, which is a good and trusted cold emailing platform for businesses globally.

2. Will ESP mismatch cause issues while sending bulk emails?

Ideally, it should not create any issues, but in bulk emails, it is ideal to send emails from the same ESP as the recipient.

3. How do you send mass emails from Gmail for free?

If you don’t want to spend anything, then the only way to send mass emails for free is by directly sending them from Gmail.

But again, this method is laborious and there are high chances that your email will be flagged by Email Service Providers (ESPs).

4. How to make bulk email sender accounts?

It is actually pretty simple to create bulk email sender accounts; all you have to do is,

• Create multiple email accounts
• Warm them up (before sending your first cold email)
• Keep their reputation high while sending emails (by continuously warming up by setting a daily percentage of emails for warmups)
