How to Send Mass Email in Gmail: 4 Methods Explained

Whether you want to reach out to leads, send a newsletter, or follow up with a batch of clients, you've got several ways to do it — and each one works differently depending on your account type, list size, and how personalized each message needs to be.

There are four approaches: BCC, Gmail's built-in Mail Merge, third-party add-ons, and a dedicated Gmail CRM like NetHunt. This guide covers all four so you can pick the right approach for sending a mass email, and avoid the limits and spam traps that catch most first-timers.

Gmail daily limits: what to know before sending bulk email

Before you run any mass email campaign, understand the platform's daily caps. Exceed the limit and your remaining messages get queued or dropped entirely.

Gmail lets you send to multiple addresses per message, but every address in To, CC, and BCC counts as one email against your quota. Sending to 1,000 contacts counts as 1,000 emails — you can't send one email and have it count as one regardless of recipient count.

If you need to send many emails beyond the Workspace cap, or if you need to scale without worrying about the ceiling at all, a tool with its own sending infrastructure is the only real answer (covered in Method 4).

How to track emails in Gmail

4 ways to send mass emails from Gmail

Choosing the right method comes down to what you actually need:

• Mail Merge — to send targeted campaigns to your contact list using a Google Sheet and Workspace
• BCC — for quick, generic sends where contacts don't need to see each other
• Add-ons — for users who can't use mail merge natively or need advanced tracking
• NetHunt CRM — for sales teams running outreach campaigns that require automation

Method 1: Mail Merge — use the Mail Merge feature to send personalized emails to multiple recipients

Gmail's built-in Mail Merge lets you send a personalized mass email directly from your inbox, using data from a Google Sheet to customize each message. In other words, it lets you send personalized mass emails at scale — without leaving Gmail. Every person on your list receives a personalized message with their name, company, or any other field you specify — not a generic blast.

Requirement: Google Workspace or Workspace Individual account. To send email in gmail directly with Mail Merge, you need Workspace — if that's you, jump to Method 3.

Daily limit: Up to 1,500 recipients (Workspace) or 500 (Workspace Individual).

How to use mail merge in Gmail — step-by-step for multiple recipients

Step 1: Open Gmail and click Compose to start a new draft.

Step 2: Click the Use mail merge icon on the right side of the "To:" line — it looks like a small spreadsheet symbol.

Step 3: Toggle the Mail Merge switch to ON.

Step 4: Click Add from a spreadsheet and connect the Google Sheet containing your contact list. Each row = one recipient; columns should include at minimum an email address and a name.

Step 5: Select the columns that correspond to your email recipients' addresses and names.

Step 6: In your message body, type @ wherever you want to insert personalized data. Gmail will suggest available fields from your spreadsheet — select the tag that matches your column header (e.g., @firstname, @company). These are the merge tags that pull unique data into each message.

How to add merge fields and use merge tags in your emails

Write your full message in the body of your email. Use merge tags wherever personalization should appear — greeting lines, subject lines, or anywhere in the message body. Then write your subject line.

Before you click Send all, use Send preview to see exactly what one recipient will receive. It takes 30 seconds and catches broken merge tags before they reach your entire list.

Limitations of Gmail's built-in merge

The built-in tool is useful, but limited: no open or click tracking, limited merge tags in subject lines, and no follow-up automation. For anything beyond a one-time send, consider a third-party add-on or a CRM.

Method 2: Use BCC to send an email to multiple recipients

BCC (Blind Carbon Copy) is the fastest way to send a message to a large group without them seeing each other's contact information or email IDs. Every person receives the same message — there's no personalization — but for quick internal updates or one-off announcements, it's zero-setup.

How to send emails using BCC in Gmail

Step 1: Open Gmail and click Compose.

Step 2: Type your own email address in the To: field. This keeps the recipient list hidden and makes the email look cleaner to the people who receive the email.

Step 3: Click Bcc on the right side of the To line.

Step 4: Paste your list of addresses into the Bcc: field, separated by commas.

Step 5: Write your subject and message, then hit Send.

When you should send email to multiple recipients individually instead of BCC

BCC works for reaching your full list quickly, but it has hard limits:

• No personalization. Everyone on the list gets identical content. There's no way to include a first name or any individual detail.
• No tracking. You won't know who opened, clicked, or bounced. What happens after the send is invisible.
• Spam risk. Mass email from a standard Gmail address via BCC triggers spam filters fast, especially with large lists.

If you need to reach each contact with a separate, personalized version for each — BCC isn't the right tool. Use Method 1 or Method 3.

Method 3: Gmail add-ons — send bulk emails from Gmail for free

If you're on a free Gmail account and want to reach contacts with customized messages, or you need tracking and automation beyond what Gmail's native tools offer, third-party mail merge add-ons fill that gap.

Tools like YAMM, GMass, and Mailmeteor install directly into Gmail and let you run campaigns from a Google Sheet. When the built-in Gmail feature isn't available, these are the go-to options. All three offer a free email tier so you can test before committing to a paid plan.

Free tier: Most of these tools allow you to send up to 50 emails per day free — that's plenty to test your setup. Paid plans unlock higher volume.

Steps to send email in Gmail using an add-on

Step 1: Install the add-on

Go to the Google Workspace Marketplace and search for a trusted mail merge tool. The main options:

• Yet Another Mail Merge (YAMM) — widely trusted and beginner-friendly; great for newsletters and non-sales sends
• GMass — most feature-rich option; supports cold email outreach, HTML email templates, A/B testing, and campaign analytics; the best option for sales campaigns with full tracking
• Mailmeteor — clean interface; good for personalized attachments; send separate files to each contact

Click Install and grant the necessary permissions.

Step 2: Prepare your Google Sheet

Create a new spreadsheet with your contacts. Each row = one recipient. Include email address, first name, and any other fields you want to use for personalization.

Step 3: Draft your email and insert personalization tags

Open a new Compose window in Gmail and write your message. Use the add-on's personalization syntax for merge fields — for YAMM, this looks like {{First Name}}; GMass uses similar tags pulled from your sheet columns. Place tags in the greeting, subject, or anywhere else in your message.

Step 4: Connect, preview, and send

Open the add-on from Gmail or Google Sheets. Select your draft and contact sheet, preview a few rows, then click Send — or schedule it for later.

Add-on sends: what to expect

Add-ons work within your Gmail account's standard daily limits. On a standard account, you can still only send emails up to the 500-per-day cap — the add-on doesn't bypass that. What it adds: proper mail merge campaigns, open and click tracking, and better deliverability management.

For campaigns at higher volume, you need a tool with its own email service infrastructure.

Method 4: NetHunt CRM — send unlimited mass emails inside Gmail

NetHunt CRM lives inside your Gmail interface and turns it into a full campaign platform. There's no separate app to learn — everything happens right there, with a CRM layer that handles contact management, email sending, and campaign tracking.

Limit: Unlimited. NetHunt uses its own SMTP, so Gmail's daily caps don't apply. You can reach tens of thousands of contacts without any ceiling.

How to run a personalized mass campaign in NetHunt

Step 1: Segment your contact list

Use NetHunt's filters to pull the exact group you want to reach — by deal stage, industry, last activity date, or any custom field. Want to reach only the leads who opened your last email but didn't reply? Filter for exactly that.

Step 2: Build your email template

Create your campaign template inside NetHunt with personalization macros: {{First Name}}, {{Company}}, {{Last Deal Date}} or any other from customer’s record. It uses mail merge to send a personalized version of each message automatically. The result: a campaign where every individual email feels like it was written for that specific person.

Step 3: Choose your sending method

NetHunt gives you three options: send via Gmail (uses your Gmail quota), via NetHunt's own SMTP server (unlimited email), or via a custom SMTP you bring yourself. For high-volume sends, the NetHunt SMTP removes the limit entirely.

Step 4: Preview and launch

Preview your campaign for individual contacts, send yourself a test, then click Send campaign. NetHunt delivers each message as a separate send to each address — each recipient won't see each other or know they're part of a campaign.

Send messages to track each individual email campaign result

Once your campaign is live, NetHunt's analytics show you exactly what happened:

• Open rate — who received the email and opened it
• Click rate — who clicked links in your email content
• Reply rate — who responded
• Bounce rate — which addresses failed to deliver
• Unsubscribe rate — who opted out

Filter your campaign contacts by status — Opened, Clicked, Bounced, Pending — and act immediately. Send a follow-up to everyone who opened but didn't reply. Remove bounced addresses from your email list. Update records in bulk based on campaign behavior.

This is what separates email tracking from a simple broadcast: every send becomes data you can act on.

Best practices for recipients in a mass email campaign

Regardless of which method you use, these habits protect your sender reputation and help you run more effective email campaigns.

Keep your list clean. Emailing stale or unverified addresses raises your bounce rate and damages deliverability on future sends. Verify your mailing list before any large campaign.

Always include an unsubscribe link. Required by law in most jurisdictions, and less damaging to your sender score than a spam report. Someone who unsubscribes is better than someone who marks you as spam.

Personalize beyond just the name. The best approach to effective campaigns is to make your email relevant to each person — not just swap in a first name. Reference their company, their industry, a specific problem they have.

Test your subject line. Keep it under 50 characters, avoid spam trigger words, and be specific about what's inside. A/B test two variants on a portion of your list before sending to everyone.

Warm up on new lists. If you're approaching a new domain or a contact list you haven't emailed before, don't go from zero to 2,000 in one day. Start small, build up gradually, and give your sending domain time to establish trust.

Preview before you send. Always compose an email to yourself as a test before sending to your full list. Ensure your email looks exactly right — check merge tag resolution, link behavior, mobile rendering, and subject line formatting.

Use custom domain tracking. If your tool tracks opens and clicks, set up tracking links under your own domain (e.g., links.yourcompany.com) instead of relying on the provider's shared default. Generic tracking domains get flagged by spam filters more often, and a custom domain keeps your branding consistent and your sender reputation tied to a domain you control.

Warm up your sending account before launching a mass campaign. Beyond warming up a new domain for a specific list, your mailbox itself needs a sending history. If you've recently created the account or it's been mostly inactive, send a smaller batch of emails over a few days first — replying to real threads, sending normal one-to-one emails — before you launch a full campaign. Mailbox providers watch for sudden jumps in volume from quiet accounts, and a proper warm-up period reduces the risk of your campaign landing in spam from day one.
