How to Send Bulk Emails in Gmail Without Getting Flagged: Step by Step Guide
Mass email, also called bulk email or an email blast, refers to sending promotional campaigns to a large group of recipients, including customers, subscribers, or leads.
Mass emailing is helpful for B2B or B2C businesses, teachers, teams, and anyone who needs to share news, updates, or offers with a large audience.
Examples of mass emailing include a company sending emails to all its customers about a sale, or a school sending updates to parents.
Gmail is one of the most popular email tools, which is used to send mass emails but Gmail has some limitations. You can only send a certain number of emails each day, and if you send too many emails, your account could get blocked.
Gmail is great for sending bulk emails to small or medium groups even with these limitations. In this guide, you will learn how to send mass emails step by step using Gmail.
We will also show you simple tools, and tips to avoid spam folders and make better marketing decisions if you send bulk emails to a large list of individuals.
What is a mass email?
A mass email is one message that is sent to many people at the same time. Businesses send an email to a big group all at once instead of sending the same email one by one.
Mass emails are used for B2B marketing, such as when a business wants to tell customers about a new product or sale. They are used for customer updates, newsletters, event invites, and other important announcements. Mass emailing helps save time and makes sure everyone gets the same information.
Gmail allows businesses to send mass emails, but it has some limits, such as how many emails they can send in a day. We will talk more about those limits later in this guide.
Is it possible to send mass emails in Gmail?
Yes, it is possible to send mass emails using Gmail. Gmail allows you to send one email to many people at the same time. You do this by using the BCC (blind carbon copy) feature BCC hides the email addresses so others can not see who else got the message.
Businesses also use Google Contacts to create a group of people and email them all at once which is helpful for small mailing lists. However, Gmail has limits on how many emails you can send per day.
You should use third-party tools such as Mailmeteor, GMass, or Mail Merge add-ons if you want to send emails to a larger group or want additional features such as tracking or templates. These third-party tools work with Gmail and make mass emailing easier and better.
How to send bulk emails from Gmail?

To send bulk email from Gmail, follow a few simple steps including creating an email list, adding your contacts, writing your message, and then sending or scheduling it.
The 4 steps to send bulk emails from Gmail are listed below.
- Step 1: Create an email list. Start by building a list of people you want to email. Businesses use Google Contacts to create a contact group or organize names and emails in Google Sheets which makes it easy to send messages to many people at once. It is a good marketing approach to group your contacts by categories such as customers, coworkers, or leads so you can send the right message to the right people, which is called segmentation. There are list-building services that help you find and organize contacts faster if you need help building a list.
- Step 2: Add contacts to Gmail. You should add the contacts to Gmail once your list is ready. One way is to go into Google Contacts and manually create or import your list which is good for small groups. It is easier to use tools such as GMass or Yet Another Mail Merge, which connect your Google Sheets list directly to Gmail for bigger lists. These tools save time and help send personalized emails to many people at once. You should learn how to build a B2B contact list for more targeted outreach if you are sending business emails.
- Step 3: Compose the Email. Start writing the email with a strong and clear subject line that gets attention. A good subject helps more people open your email. Next, use personalization which means using placeholders such as {First Name} so each email feels personal. Keep your message short, friendly, and easy to understand. Try not to use too many links or spammy words, as these trigger spam filters and stop your email from being seen.
- Step 4: Sending or scheduling the email. Businesses send their email instantly or use Gmail’s built-in “Schedule Send” feature to choose the best time. Sending at the right time helps more people see and read your message. Businesses also track if people open their emails or click on the links if they are using tools such as GMass or Mail Merge. You should try Google Groups if you are emailing a group of people. Make sure to follow email rules and check out these tips to avoid spam risks when sending bulk emails.
What are Gmail's limitations for mass emails?

Gmail’s limitations for mass emails include daily sending limits, simple email design, and risks of being marked as spam.
Gmail’s limitations for mass emails are listed below.
- Sending limits. Gmail puts a limit on how many emails you send each day. You are allowed to send up to 500 emails per day if you are using a free Gmail account. The limit goes up to 2,000 emails per day if you have a Google Workspace (business) account. Google stops your emails or even locks your account for a while if you send more than these limits. You can use SMTP relay services such as SendGrid or Mailgun to avoid this problem. These services connect with your Gmail and let you send a much larger number of emails safely. You should consider how many cold emails to send per day or check Google’s official email sending limits, if you are sending cold emails.
- Gmail’s basic email design restrictions. Gmail’s built-in email editor is very basic as it does not have fancy design tools such as templates, drag-and-drop builders, or detailed formatting options. This means your emails look plain when trying to create eye-catching marketing messages. You should use Google Docs to design your email with better formatting, and then copy it into Gmail. It is better to use an email marketing or sales prospecting tool if you want to create professional-looking emails. These third-party tools give you more design choices and help track how people respond to your emails.
What are the best practices for successful mass Emailing in Gmail?

The best practices for successful mass emailing in Gmail are avoiding spam filters, making your emails mobile-friendly, sending at the right time, using an email signature, and following up with your contacts.
The 5 best practices for successful mass emailing in Gmail are listed below.
- Avoiding spam filters. Spam filters block your emails from reaching the recipient's inboxes. Do not use too many links, large images, or spammy words such as “Buy now” or “Free.” to avoid this problem. Make sure your email list is clean by removing fake or unused addresses. You should use tools to verify email addresses without sending them. Always include an unsubscribe link, use a clear subject line, and send from a real email address to stay out of spam folders.
- Ensuring mobile friendliness. Many people read emails on their phones, so your email should look good on small screens. Use short paragraphs, large fonts, and simple formatting. Avoid wide tables or images that do not resize well. Test your email on a phone before sending it to make sure it is easy to read. A mobile-friendly email helps more people open, read, and click on your message.
- Scheduling Emails for optimal open rates. Timing is important when sending emails. Sending them at the wrong time causes your message to get lost in a crowded inbox. Use Gmail’s “Schedule Send” feature to send emails when people have a chance to check their inbox in the mornings or on weekdays. Testing different days and times also helps you find the best schedule for your audience. Better timing means more open rate and better results.
- Automating your Email signature. Adding an email signature saves time and makes your email look professional. You set it up once in Gmail, and it will appear in every email you send. A good signature includes your name, job title, company, and contact information. You can even add a logo or a link to your website. Automating your signature keeps your emails consistent and trustworthy.
- Following up for better engagement. Sometimes people miss your first email, so sending a follow-up is necessary. Wait a few days, then send a friendly reminder. Keep it short and refer to your first message. Tools such as GMass or Mail Merge help you schedule automatic follow-ups. Following up increases your chances of getting a reply and building a better connection. Use lead generation tools and a clean B2B contact database to reach the right people and get better results.
What are the common issues in sending Gmail mass emails?

The common issues in sending Gmail mass emails include bounced emails, and Gmail's suspicious activity alerts.
The 2 common issues in sending Gmail mass emails are listed below.
- Resolving bounced emails. A bounced email means the message did not reach the person you sent it to. Bounced email happens if the email address is wrong, the inbox is full, or the domain no longer exists. Too many bounces damage your sender's reputation and lower your chances of reaching other inboxes. Always use a clean and updated email list to avoid this problem. You can remove old or fake contacts and use tools to check if an email is real before sending it. Never depend on random free email lists, as they are outdated or full of invalid addresses.
- Navigating Gmail’s “suspicious activity” alerts. Gmail shows a “suspicious activity” warning if it gets a hint that you are sending too many emails or seeing something unusual. Gmail stops you from sending more emails for a while. This happens if you are sending emails too quickly, copying and pasting the same message, or using links that look unsafe. Send emails slowly in batches, personalize your messages, and use trusted links to avoid this issue. Stop sending emails for a few hours, review your list, and check your Gmail security settings to make sure your account is safe if you get an alert.
